When user type in any key from the keyboard, the software trigger API is called to start the conversion. Then it polls the conversion sequence A's flag till the conversion is completed. When the conversion is completed, just print the conversion result to terminal.Project Information1.what are ADC conversion sequences? A conversion sequence is a single pass through a series of A/D conversions performed on a selected set of A/D channels. Software can set-up two independent conversion sequences, either of which can be triggered by software or by a transition on one of the hardware triggers. Each sequence can be triggered by a different hardware trigger. One of these conversion sequences is referred to as the A sequence and the other as the B sequence. It is not necessary to employ both sequences. An optional single-step mode allows advancing through the channels of a sequence one at a time on each successive occurrence of a trigger. The user can select whether a trigger on the B sequence can interrupt an already-in-progress A sequence. The B sequence, however, can never be interrupted by an A trigger. 2. How to use software-triggered conversion? There are two ways that software can trigger a conversion sequence: 1. Start Bit: The first way to software-trigger an sequence is by setting the START bit in the corresponding SEQn_CTRL register. The response to this is identical to occurrence of a hardware trigger on that sequence. Specifically, one cycle of conversions through that conversion sequence will be immediately triggered except as indicated above. (In this example, we use this way.) 2. Burst Mode: The other way to initiate conversions is to set the BURST bit in the SEQn_CTRL register. As long as this bit is 1 the designated conversion sequence will be continuously and repetitively cycled through. Any new software or hardware trigger on this sequence will be ignored. Program Flow1.This example demonstrates how to configure the A sequences with polling, assigning one channel with software trigger, you can configure channel via "DEMO_ADC_SAMPLE_CHANNEL_NUMBER". 2.Before configuration of the ADC begins, the ADC is put through a self-calibration cycle. 3.After ADC channels are assigned to each of the sequences, the software trigger is chosen. Setting SEQA_CTRL_START to '1' will trigger sequence A. 4.After ADC channels are assigned to each of the sequences, if the user enters any key via terminal, software trigger will start. 5.Read the corresponding DATAVALID field with polling to judge whether the conversion completes and the result is ready. If the result is ready, the example will printf result information to terminal. The lpc_adc_burst example shows how to use LPC ADC driver with the burst mode.In this example, the internal temperature sensor is used to created the input analog signal.When user type in any key from the keyboard, the burst mode is enabled. Then the conversion sequence A would be started automatically, till the burst would be disabled in conversion completed ISR. Project Information1.what are ADC conversion sequences?

(In this example, we use this way.) 3. What kinds of interrupt do ADC have? There are four interrupts that can be generated by the ADC: • Conversion-Complete or Sequence-Complete interrupts for sequences A and B • Threshold-Compare Out-of-Range Interrupt • Data Overrun Interrupt Any of these interrupt requests may be individually enabled or disabled in the INTEN register. Program Flow1.This example demonstrates how to configure the A sequences with burst mode, you can configure channel via "DEMO_ADC_SAMPLE_CHANNEL_NUMBER". 2.Before configuration of the ADC begins, the ADC is put through a self-calibration cycle. 3.Enable the Conversion-Complete or Sequence-Complete interrupt for sequences A. 4.After ADC channels are assigned to each of the sequences, if the user enters any key via terminal, burst mode will start. 5.When the first conversion completes, the interrupt would be triggered. The ISR will stop the burst mode and print conversion result to terminal. The lpc_adc_dma example shows how to use LPC ADC driver with DMA.In this example, the internal temperature sensor is used to created the input analog signal. When user type in any key from the keyboard, the software trigger API is called to start the conversion. When the ADC conversion is completed, it would trigger the DMA to move the ADC conversion result from ADC conversion data register to user indicated memory. Then the main loop waits for the transfer to be done and print the result to terminal.Project Information1.what are ADC conversion sequences?

How to use DMA to work with ADC? The sequence-A or sequence-B conversion/sequence-complete interrupts may also be used to generate a DMA trigger. To trigger a DMA transfer, the same conditions must be met as the conditions for generating an interrupt. Remark: If the DMA is used, the ADC interrupt must be disabled in the NVIC. Program Flow1.This example demonstrates how to configure the A sequences with interrupt, assigning one channel with software trigger, you can configure channel via "DEMO_ADC_SAMPLE_CHANNEL_NUMBER". 2.Before configuration of the ADC begins, the ADC is put through a self-calibration cycle. 3.Configure the DMA and DMAMUX to work with ADC sequences.4.Enable the Conversion-Complete or Sequence-Complete DMA for sequences A. 5.After ADC channels are assigned to each of the sequences, if the user enters any key via terminal, software trigger will start. 6.When the conversion completes, the DMA would be requested.7.When the DMA transfer completes, DMA will trigger a interrupt. ISR would set the "bDmaTransferDone" to 'true'. Then main function will print conversion result to terminal. The lpc_adc_interrupt example shows how to use interrupt with LPC ADC driver.In this example, the internal temperature sensor is used to created the input analog signal. When user type in any key from the keyboard, the software trigger API is called to start the conversion.

The power_manager_lpc application shows the usage of normal power mode control APIs for entering the three kinds of low power mode: Sleep mode, Deep Sleep mode and Sleep Power Down mode. When the application runs to each low power mode, the device would cut off the power for specific modules to save energy. The device can be also waken up by prepared wakeup source from external event. Tips: This demo is to show how the various power mode can switch to each other. However, in actual low power use case, to save energy and reduce the consumption even more, many things can be done including: - Disable the clock for unnecessary module during low power mode. That means, programmer can disable the clocks before entering the low power mode and re-enable them after exiting the low power mode when necessary. - Disable the function for unnecessary part of a module when other part would keep working in low power mode. At the most time, more powerful function means more power consumption. For example, disable the digital function for the unnecessary pin mux, and so on. - Set the proper pin state (direction and logic level) according to the actual application hardware. Otherwise, the pin cirrent would be activied unexpectedly waste some energy. - Other low power consideration based on the actual application hardware. - In order to meet typedef power consumption of DateSheet manual, Please configure MCU under the following conditions. 鈥?Configure all pins as GPIO with pull-up resistor disabled in the IOCON block. 鈥?Configure GPIO pins as outputs using the GPIO DIR register. 鈥?Write 1 to the GPIO CLR register to drive the outputs LOW. 鈥?All peripherals disabled.

The SHA Example project is a demonstration program that uses the KSDK software to generate SHA checksums. The Shell Demo application demonstrates to control Leds by commands. The spi_interrupt_b2b_master example shows how to use spi functional API to do interrupt transfer as a master:In this example, the spi instance as master. Master sends a piece of data to slave, receive data from slave,and checkif the data master received is correct. This example needs to work with spi_interrupt_b2b_slave example. The spi_interrupt_b2b_slave example shows how to use spi functional API to do interrupt transfer as a slave:In this example, the spi instance as slave. Slave receives data froma master and send a peiece of data to master,and check if the data slave received is correct. This example needs to work with spi_interrupt_b2b_master example. The spi_interrupt_board2board_master example shows how to use spi driver as master to do board to board transfer withinterrupt:In this example, one spi instance as master and another spi instance on othereboard as slave. Master sends a piece ofdata to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct. The spi_interrupt_board2board_slave example shows how to use spi driver as slave to do board to board transfer with interrupt:In this example, one spi instance as slave and another spi instance on other board as master. Master sends a piece ofdata to slave, and receive a piece of data from slave. This example checks if the data received from master is correct. The spi_polling_board2board_master example shows how to use spi driver as master to do board to board transfer with polling:In this example, one spi instance as master and another spi instance on othereboard as slave. Master sends a piece ofdata to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct. The spi_polling_board2board_slave example shows how to use spi driver as slave to do board to board transfer withpolling:Notice: The SPI slave of this example uses interrupt mode, as there is no polling mode for SPI slave.In this example, one spi instance as slave and another spi instance on other board as master. Master sends a piece ofdata to slave, and receive a piece of data from slave. This example checks if the data received from master is correct. The SPIFI DMA Example project is a demonstration program that uses the KSDK software to program external serialflash using DMA and read through AHB bus. The SPIFI Polling Example project is a demonstration program that uses the KSDK software to program external serialflash using polling and read through AHB bus. The touch_cursor demo shows how to use LCD hardware cursor and position it using touch panel.In this example, a 32x32 cursor is shown. The cursor's position is changed in reaction to detected touch. This example shows how to use the DMA driver to implement a double buffer receive scheme from the USARTThe example shows the double buffer constructed using two descriptors (g_pingpong_desc). These descriptors are cycled from one to the other.Things to note- The descriptors of the ping pong transfer need to be aligned to size 16- The inital transfer will perform the same job as first descriptor of ping pong, so the first linkeage is to go to g_pingpong_desc[1]- g_pingpong_desc[1] then chains the g_pingpong_desc[0] as the next descriptor- The properties are set up such that g_pingpong_desc[0] (and the initial configuration uses INTA to signal back to the callback)- g_pingpong_desc[1] uses INTB to signal to the callback- The scheduled callback uses this information to know which data was last writtenA note on PerformanceThe intent of this example is to illustrate how a double-buffer scheme can be implemented using the dma. The performance of this example will be limited to how quickly the echo printer can read-out the data from the ping pong buffer and display it. This means that the example will work well if characters are entered at a rate where the DMA callback to echo the string can keep up with the input stream. Connecting the USARTRX to a continuous fast speed will cause the DMA to fall behind. The usart_dma ring buffer example shows how to use usart driver with DMA:In this example, one usart instance connect to PC through usart, the board will send back all characters that PC send to the board. The usart_dma example shows how to use usart driver with DMA:In this example, one usart instance connect to PC through usart, the board willsend back all characters that PC send to the board.Note: The example echo every 8 characters, so input 8 characters every time.
