I2C Clock Speed Portenta H7
Any idea how to reduce the I2C clock speed on a Portenta H7 to less than 100KHz?
The wire library allows me to do it on other devices, and I can increase the clock speed on the H7, however when I try to reduce it, it just stays at 100KHz, despite saying it can handle down to 10KHz.
Would really appreciate some help on this one.

Portenta H7 I2C clock speed
Hi all, Hardware (Portenta H7 Lite, mid carrier) Software (Win11, Arduino IDE 2.3.4, Wire library) We have working code for I2C communication which as default runs at the I2C clock speed of 100kHz. We want to be able to run at 40kHz, but if we try and use the setClock() function with 40000 it compiles, downloads then the H7 goes into SOS mode,...
