I am using the MCP2221 to read analog values from an ADC MCP3424, and noticed a bug when reading bytes from the analog data register.
The problem only happens when reading i2c and the first bytes are 0x00, but even trying to read 5 bytes, it does not reply any further bytes that aren't 0x00.
Please see images below.
First received byte is 0x00:
First received byte is 01:
Do you have any workaround for this issue? I tried to download latest driver and DLL, but still no luck solving this.
Note: It works fine inside MCP3331 I2C/SMBus Terminal (see below)
