Hi,I am trying to connect raspberry Pi with STM32 via I2C.. for 2 weeks now.. going to the specifics: RPI3 is a master, STM32 is a slave, I use HAL library and CubeMX. All communication should be the simplest possible. I want to send / receive one by...

Hello,I am trying to connect RaspberryPi (master) with STM32 (slave) via I2C. STM has to "simulate" several devices (exactly 10) on the I2C bus. The problem is that I can set max 2 addresses (at least in Cube - HAL libraries). Ideally it would be lik...

Thank you, I did the same on NUCLEO-F401RE (based on your code) and it works like a charm.Both receiving and transmitting.When I try to do it identical on my board with STM32F105VCT I get that ..STM sends the address again instead of 0x44. The code i...

I wasn't aware of this, thank you very much. Fortunately, clock of uC is probably fast enough so I don't have to use stretching (after all MUXs/PLLs is 72 MHz). However, this still doesn't solve my problem. Most of the time I tried to solve it withou...

I spent some time on this yesterday and today. It seems that HW checks by itself if the addresses match and then generates an interrupt. I haven't found a place in code where I could manually check if the address is ok or not: / If the address doesn'...

Thank you for your answer. You're right, I didn't say which stm I use. It is: stm32f105vct6.Of course, I read all the datasheets I found. But unfortunately I didn't find a direct answer there. I thought it could be done at the HAL level, but I think ...
