Hi there,
I've got a LaunchPadXL-TMS320F28069M and set up I2C communications with a small pressure sensor... no problems there. I used the dedicated I2C pins P32 and P33 as the SDA and SCL, respectively.
The issue I've got is that I have a development board that uses a TMS320F28069M from a Siemens TAPAS inverter board - a few years back Siemens held a promo to get people using these flexible inverters for various projects. I based a project on it using analogue sensors and it lost a lot of accuracy. I'd like to rerun results for this project using the new I2C-protocol sensor I have on the TAPAS board for comparisons... problem is that there doesn't seem to be anything dedicated for I2C on their schematics.
The question I have is as follows: is there a way of using non-dedicated GPIO pins for I2C protocol instead? Or can I somehow convert I2C to SPI...? Or is there another way around this?
I've had a long look at the forums and cannot find any relevant topics on this (I am aware that there probably will be some, but I am pretty naive to the subject. I may well have read through them and not even realised it was answering my question!)
Cheers,
Jon
