I am building something with raspberry pi. I am using the 16x32 led matrix as well as the port expander (MCP23017). Both use the SDA and SCL pins. I am having trouble hooking it up. I realize this may be a rookie question - but is this possible?
I have my MCP23017 on a breadboard. Anytime I put in the SDA/SCL pin for the matrix into the appropriate row it makes it so the MCP is no longer detected. Any help would be appreciated. Thanks!
