SAR ADC

[matthiasuhlmann]

Hi All,

I need to setup the ADC_16 to measure several input measurements.

Can somebody help me to set up a propper implementation?

- how can i set up a smaple sequence? (e.g. AD10,AD12,AD20)?

- how can i use DMA to prevent using IRQ's?

- Is there somewhere a code example available?

Thank you!

Matthias

Hi Matthias,

You can look in AN4583, where the SAR ADC is used for PFC implementation along with the DMA. This will solve all the above three queries. the link for the same is http://cache.freescale.com/files/microcontrollers/doc/app_note/AN4583.pdf?&Parent_nodeId=&Parent_pag...

You can also download the code from freescale web : RDPFCPMSMMC56F84789: Dual Sensorless PMSM FOC with PFC Reference Design: Dual Sensorless PMSM FOC wi...

Note: if the answer helps please mark it as helpful/correct.
