RE: Help with adding an I2C recovery pulse

Yes I found that function as I mentioned, but I had a hard time finding where the function nrfx_twim_bus_recover() that it calls lives. I looked again this morning and I found that it ultimately ends up calling nrfx_twi_twim_bus_recover in nrfx_twi_twim.c.

I did manage to get this to work, so I'll close this topic. A note to future post-finders, the code in nrfx_twi_twim_bus_recover checks to see if the SDA pin is high and it doesn't send the reset pulse if it is. I guess this procedure is only meant to release a stuck SDA line.

const struct TM065049_config *config = m_dev_copy->config;

i2c_recover_bus(config->i2c.bus);

I just opened NCS 2.6.1, and I could see that the

i2c_nrfx_twim_recover_bus() function is defined in i2c_nrfx_twim.c file
