Other Parts Discussed in Thread: USB2ANY, , MSP430G2553, TMP112, LP5024
I am trying to set up I2C communication with the LP5024EVM using an MSP430G2553. I have already checked that the board is working through the USB2ANY and am now trying to communicate with it with my MSP430. I have gotten communication running with another peripheral (TMP112) so I don't believe the problem is on the MSP430's side.
Are there any jumpers that need to be changed in order to use the EVM with I2C? I have an external 5V power supply and have noted all my current jumper connections below in red:
My specific issue that I am currently encountering is that when I don't have the EVM on the I2C lines, there is no problem. When I connect the SCL and SDA lines of the EVM to the rest of the system, the line is held high and all communication stops.
Thanks for your help,
