I am now working on an ADC module (ADS7823) with raspberry pi 3B+. The coding is in python3 and I imported the SMBUS. Till now it works very well.
There are three kinds of working mode for ADS7823 which are Standard mode(100Khz),Fast mode(400Khz) and High speed mode(3.4MHz).The speed here is thr speed of SCL. However, I found that the SMBUS only support 10kHz to 400kHz, it can not support 3.4Mhz, so could anyone tell me are there any python libraries which can support I2C high speed mode???
