I2C Interrupts

[JGóme.1]

Hello everyone!

I would like to know what requirements are needed to work with sensors in a STM32 core F401RE using I2C Interrupts, and if that is possible.

Thanks.

I was searching in Internet but I don't find nothing.

There is quite a lot of information within the HAL source.

https://github.com/STMicroelectronics/STM32CubeF4/blob/master/Drivers/STM32F4xx_HAL_Driver/Src/stm32f4xx_hal_i2c.c#L64

As well as many examples in the CubeMX repository.

I have already tried with the repository examples, however it only shows examples of communication between two cards, which I have not been able to make work either.

I also want to know if something in particular is needed to read the data from a sensor, specifically a DLHR-F50D pressure sensor

Doesn't bode well for interfacing with another sensor then.

Just an I2C or SPI interface, power, appropriate hardware and wiring, and a workable code.

CAN YOU HELP ME WITH AN EXAMPLE

Hi @Julian Gómez​ ,

Have a look at this FAQ STM32 I2C does not work, describes few tips related to I2C peripheral on STM32 devices.
