yiancar 1acafc94f4 Correct ARM STM32 I2C frequency. (#7080)
It was beleaved that this setting result in a 400Khz I2C bus.

This was incorrect, actual frequency measure with a logic analyzer was around 150Khz.

This is derived from the excel sheet linked in the .h file.
Also confirmed with the ST IDE.
