    ADC SAR data acquisition, using DMA, buffer and then transmit UART.

    MaBo_3742841

      Hi, I'm in my first post in the community.

       

      I'm in a project where I finally want to transmit 4 analog signals via UART, now I get to the penultimate phase where I test 1 signal.

       

      I opted to use a buffer since when sending several samples (which is my goal), when receiving in Matlab it did not arrive well.

      I checked the ADC by sending to the SRAM of the PSoC and it arrives fine.

       

      My problem specifically is at the time where the DMA to save to the SRAM of the PSoC ends and I have to activate the DMA to send via UART.

      I already run out of ideas.

       

      Regards.
