Other Parts Discussed in Thread: TMS320C6678, ADS131E08
1、After the SPI communication is normal, the register of ADS is configured as follows:CONFIG1=0x92, CONFIG2=0xE0, CONFIG3=0xC0, FAULT=0x00, CHnSET=0x10(n=1-8);
2、Then, EVM is used to measure the output of linear power supply (its output voltage is 1.778V measured by multimeter), and EVM channels 1, 2 and 3 are used to measure, and the other channels are not connected.
After measurement and conversion, it is found that sometimes the measurement data is wrong, may I ask what may cause this?
