cmsis_lpuart_edma_transfer
Keil Studio, µVision AC6CMSIS-Driver defines generic peripheral driver interfaces for middleware making it reusable across a wide range of supported microcontroller devices. The API connects microcontroller peripherals with middleware that implements for example communication stacks, file systems, or graphic user interfaces. More information and usage methord please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.The cmsis_uart_edma_transfer example shows how to use uart cmsis driver with EDMA:In this example, one uart instance connect to PC through uart, 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.

dac_basic
Keil Studio, µVision AC6The dac_basic example shows how to use DAC module simply as the general DAC converter.When the DAC's buffer feature is not enabled, the first item of the buffer is used as the DAC output data register.The converter would always output the value of the first item. In this example, it gets the value from terminal,outputs the DAC output voltage through DAC output pin.

dac_buffer_interrupt
Keil Studio, µVision AC6The dac_buffer_interrupt example shows how to use DAC buffer with interrupts.When the DAC's buffer feature is enabled, user can benefit from the automation of updating DAC output by hardware/software trigger. As we know, the DAC converter outputs the value of item pointed by current read pointer. Once the buffer is triggered by software or hardware, the buffer's read pointer would move automatically as the work mode is set,like normal (cycle) mode, swing mode, one-time-scan mode or FIFO mode.In this example, it captures the user's type-in operation from terminal and does the software trigger to the buffer.The terminal would also display the log that shows the current buffer pointer's position with buffer events.

dac_continuous_pdb_edma
Keil Studio, µVision AC6The demo shows how to use the PDB to generate a DAC trigger and use the DMA to transfer data into DAC buffer.In this example, DAC is first set to normal buffer mode. PDB is as DAC hardware trigger source and DMA would work when DAC read pointer is zero. When run the example, the DAC is triggered by PDB and the read pointer increases by one,every time the trigger occurs. When the read pointer reaches the upper limit, it goes to zero directly in the next trigger event.while read pointer goes to zero, DMA request will be triggered and transfer data into DAC buffer. The user should probethe DAC output with a oscilloscope to see the Half-sine signal.
