+1 for the config file option. About the later, I think it would be nice if ebuildtester could run on different OS (eg: mac). So by switching to docker python...

That sounds like making UX worse. I think adding a config-file flag is nice in cases where the configuration is in unusual paths or for a specific configuration that is...

Thank you for the fast reply. Certainly, I was checking with a coworker and seems there is some bug with the board itself.

After fixing the hardware issue we checked that the I2C was working with a different I2C peripheral and then tried again with the MCP23017, but we still have timeouts. When...

@YanKE01 I have been debugging a bit more and seems that by default the MCP23017 is in sequential mode but the library seems to be accessing MCP23017 as if it...

We have the SCL and SDA pins soldered, can you share the source code to built it? We confirmed our hardware works properly and using a different library ( https://github.com/UncleRus/esp-idf-lib/tree/master/components/mcp23x17...

May it be that your local i2c_bus component is a different version or have uncommitted fixes that make it work?

(sorry, previously I got confused and thought the other issue was this one) I noticed that the writes seems to work but the reads didn't. It may be related with...

We acquired few days ago something similar for the purpose of testing this: an expand-click from Mikroe (https://www.mikroe.com/expand-click) The same I reported about the timeout can be reproduced using this...
