How to transfer A/D conversion result using DTC

Posted: 08 Aug 2012     Print Version  Bookmark and Share

Keywords:DTC  A/D converter  RAM 

In this document, Renesas Electronics describes an example of using the DTC (in repeat mode) in conjunction with the A/D converter (in software trigger mode, scan mode, and one-shot conversion mode). Perform A/D conversion on analogue input voltage input to pins P20/ANI0 to P23/ANI3 while in scan mode, and use DTC transfer to store the A/D converted value to the RAM. Perform A/D conversion for individual pins successively. Every time A/D conversion for a pin is completed, store the converted result to the 10bit A/D conversion result register (ADCR), activate the DTC, and transfer the A/D converted result from the ADCR register to the RAM. When A/D conversion and DTC transfer for all of the above pins are completed, an A/D conversion end interrupt request is generated.
