I2C demo

CMoran — Fri, 19 Nov 2021 17:30:03 GMT

Hello! I'm trying to learn more about i2c and have imported an SDK example to assisting in the learning process. Although I've run into some issues debugging/running the demo. The debug console will display some of what the demo is suppose to print on the Serial COM terminal I have opened but then it hangs and never makes it to the rest of the demo. I stepped through the demo and it is stuck on a while loop that is waiting for the slave to finish receiving (while(g_SlaveRxIndex < LPI2C_DATA_LENGTH)). It was the lpi2c interrupt demo, which didn't come with separate master/slave code so I assumed the demo would run on my board without any additional peripherals.

I'm new to embedded systems coding, any insight would be helpful.

Board is: MIMXRT1170-EVK

SDK is: SDK_2.x_MIMXRT1170-EVK (SDK Version 2.10.1)

Demo is: evkmimxrt1170_lpi2c_interrupt_cm7

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Before answering your question, I was wondering if you can share the printed result.
Further, I'd like to confirm that whether you set the MIMXRT1170-EVK as the readme.txt illustrates.
Have a great day,
TIC
