Bernd Porr 75cc3ef8ba usbdux: usbduxsigma: fixed timing issues between ADC and DAC ... When sync ADC and the DAC was running at the same time the ADC showed spikes in the signal. This happened when just before the DRDY from the ADC was triggered a DAC interrupt was dealt with. ADC and DAC share the same SPI bus and priority is now given the ADC. The DAC values are now first stored in a buffer and are only send to the DAC once the ADC has finished converting all channels (start = 0) so that the SPI bus is definitely quiet for about 100us.
