Hi, all.
I working at ADC sampler implementation. ADCsamplerhas a next flow:
Timer 1 generate sample rate at 200kHz.At every Timer 1 CC2 interrupt ADC1,ADC2,ADC3 take a sample.DMA is used to transfer s...
Posted on August 21, 2014 at 14:56Any way, thank for your reply.Probably I'll make double layout (for USART and SPI) to receive the data. When data is received, I'll will search for ''010'' bit sequence that represents some kind of header.I'll see i...
Posted on April 25, 2013 at 09:32I have found the problem. I didn't enable DDS at ADC->CCR.After reading once again ADC manual : found at 11.8.1: - Requests can continue to be generated if the DDS bit is set to 1. This allows configuring the DMA in ...
Posted on April 25, 2013 at 07:02The buffer size is 30 (3 channels * 10 samplers at 50 usec). The reason why I want use is simple, I do not want to perform addition calculation of start and end frame indexes in a circular buffer. With double buffer...
