    UART DMA?

    tavonunez260_3626206

      Hi community, it's me again. I have had a very good time working on my project. I am developing an EMG Measuring device. My purpuse is to send  ADC signals through serial port

       

      I am using these modules

       

      ADC SAR --> FILTER --> VDAC --> ADC DELSIG --> UART.

       

      The signal filtered that comes back from the VDAC goes back to the ADC DELSIG. I haven't found a way to transmit directly from the filter to the UART through polling or DMA. I tried through DMA with the following register UART_TXDATA_PTR, but I get some random output in the serial port. Do you have any ideas? I would appreciate it.
