Hello,I am having difficulties trying to sample both channels of the LTC1865 ADC and was hoping someone could point out my mistakes. This is my function to sample the channels. I am using the STM32WB55 micro.unsigned int READ_External_ADC(int chann...

Hello,I am using an STM32WB55 and am trying to figure out how to get the current time including milliseconds using an RTC and display that time in 6 byte hex format. I would most likely call the GetTime() based of a millisecond timer if that is the ...

Hello,I am trying to trigger each DMA read of my SPI to happen on update event Trigger output of my Timer but I don't think I have it setup correctly.I've seen this done using the internal ADC, where you can set the external conversion trigger source...

Hello,I need to sample an ADC at 20ms using SPI. I setup a timer interrupt to do this, but I would like to fill a double buffer at SPI_RxHalfCplt and RXCplt.My timer seems to be working correctly, however the Rx Half Complete Callback is being Called...

Hello,I have a 246 x 3 matrix that I have filled with counter values in the below for loops. I for some reason cannot get the HAL_UART to output individual columns of this matrix. for(i=0; i<246; i++) { for(j=0;j<3;j++) { Audio_Data[i][j] = c...

So would I need DMA setup for the timer as well as the SPI? Would you happen to be able to show me the lines of code that would be needed for this?Thanks for the response

So if I want ping pong a double buffer of size 492 bytes, but want to sample the ADC at 20ms, would I set the timer up to trigger at 20ms * BUFFER_SIZE? Which would fill the whole buffer at my sample rate and trigger the DMA receive half complete an...

I only want to take one sample (16-bit) from the ADC each time the timer interrupt is triggered. However, I would like to know when the data buffer is half full and full in order to do a ping pong structure with the data. Is this possible?

what about if I wanted to copy a single column into a separate single dimension array using memcpy?
