Other Parts Discussed in Thread: ADS1202, AMC1304M25
Digital filtering is currently being attempted using DFSDM in STM32F7, with filter inputs supporting SPI, Manchester encoding, PDM, and parallel inputs.
Customer has the following questions about AMC1304:
1. What should the digital filter interface after AMC1304 be, is it the same SPI used as the ADS1202? If so, I need to read the data on the rising or falling edge.
2. Is the digital filter followed by a sin3 OSR 256? Can the processed values be read directly?
3. The datasheet says that the voltage value is calculated based on the ratio of 0 and 1 of the data stream, then does the range of this data stream refer to data over 128 cycles? Does it mean that I need to acquire values over 128 cycles and compare the ratio of 0 and 1 values?
