First, I can use I2C with SCL on pin P1.11 and SDA on P1.12 with NRF54L15DK.
But then, when I try to change SCL to P0.03 and SDA to P0.02. I2C does not work anymore.
The log for logic analyzer shows that there is only 1 pulse on the SDA pin.
My project: simple_i2c_sender_nrf54L15DK.zip
Log from logic analyzer:
Please support me on this topic, If any further information is needed just let me know.
Thank you.
Hello,
To use GPIO port P0, you need to use TWIM30 as instance
You can try to Change your overlay to use TWIM30 for P0.03 and P0.02. Using TWIM21 with these pins is not supported on nRF54L15.
