LP-MSPM0G3507: I2C target mode

Pakho

Tool/software:

To the TI Team:

I'm testing the i2c_target_rw_multibyte_fifo_interrupts sample code and encountered an issue when remapping the I2C pins. When I configure SDA as PA10 and SCL as PA11, the code fails to function. Other pin combinations work correctly, but pins marked in the red square (including PA10/PA11) consistently cause issues.

My questions:

Are there mandatory modifications I might have missed for these specific pins?
Is it possible to implement I2C using PA10 and PA11? If so, what changes are required?

Appreciate your guidance!

Hi,

Are you using the launchpad or yourself own board?

Hi Pakho,

Please be noted that there are two jumpers in the launchpad that you need to pay attention, and check whether you have moved the jumper to connect 2-3 and then using PA10 and PA11 in launchpad.
