I have two stm32 boards STM32F103ZE and STM32F103RC I am trying to use an ultrasonic sensor in a project, the code works on the STM32F103RC board and but doesn't work on the other, I changed configuration and pins but still nothing, what could cause this

Are we just guessing?

A bug in the code.

A hardware error.

A bad/counterfeit chip.

A more objective approach would be to look at what is "not working", determine why, and fix it.

Inability to communicate salient information?

Changed what to what? Assume forum members lack psychic skills.

Board level design differences? I2C? Pull-ups?

Pins involved?
