I2C errors and interrupts

Hi there, I'm using the STM32H7 to talk to a CS2000 clock chip over I2C. I'm using interrupt mode.I'm just trying to read the chip's ID register for starters. Despite the CS2000 ACKing the first 'setup write' byte, it won't write the second byte (wit...

Hi everyone, I am fairly new to ST and I'm working on a project where i need 8 phase shifted pwm signals(each phase shifted by 45 degrees and same duty cycle)

i was thinking if there is a way i could generate 4 timers phase shifted by 90 degrees wrt each other so that i could use them to generate 2 pwm signals (on each timer using asymmetric mode) . can this be done? if not, is there any other way i could ...

Resolved! Can someone identify this IC?

I would have thought the text on it would prove to be meaningful but apparently according to every search I have tried it is not. Thanks for your help.

Temperature of the internal temperature sensor

Using STM32F0308C on a custom board. When I read the temperature sensor I am getting 1765 and the TS_CAL value is 1778.Supply voltage is 3.3V, VREF_INT is 1524 and I am reading 1525 on the internal reference. So I assume I must apply a 1524/1525 corr...
