I2C_TIMINGR is configured for I2C bus speed of 400kHz. Is his configuration correct? PRESC[3:0] = 0010 (PRESC = 2) SCLDEL[3:0] = 0001 (SCLDEL = 1) SDADEL[3:0] = 0001 (SDADEL = 1) SCLL[7:0] = 00001010 (SCLL = 10) SCLH[7:0] = 00001010 (SCLH = 10) Is it correct or not?

I2C_TIMINGR is configured for I2C bus speed of 400kHz. Is his configuration correct?

PRESC[3:0] = 0010 (PRESC = 2)
SCLDEL[3:0] = 0001 (SCLDEL = 1)
SDADEL[3:0] = 0001 (SDADEL = 1)
SCLL[7:0] = 00001010 (SCLL = 10)
SCLH[7:0] = 00001010 (SCLH = 10)

Is it correct or not?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
