Using the Microchip MCP2221 I2C Terminal Program i am able to read 0x23 ( 35 ) bytes with no problem, so i'm pretty sure that my hardware is ok.
When I try to read 0x23 bytes with PYMy2221A I can not read any more than 8 bytes before it crashes, SCL remains low. ( it is the MCP2221 that is holding it down ).
mcp2221.I2C_Read(0x60,0x23)
Fails
I can read all teh data if i do make three reads of 8 bytes, and one of 3 bytes, and join them together later. However i have to put small pauses otherwise it crashes as well.
I am having an issue with Long I2C Reads.

This works
Is this by design, or is this a bug?
