I need to send 2 bytes over the I²c bus with a STM32L432 as slave and a Raspberry Pi as master. But the clockpulse of the SCL is to wide.

In the code below I send 2 bytes with my STM32 (I've chosen a number higher then 255 (340) so it needs to send the data in 2 bytes) but on the scope I cant find this data. I guess it's because of the wide clockpulse and the Rpi expect an ACK. Instead...

Im using the STM32L432 and I need to transmit data to a Raspberry Pi over I²c. In my project the STM32 is a slave and the Raspberry Pi is the master.

I am able to send & receive 1 integer over the I²c bus but I'm stuck how I can send more integers in 1 commando. Can someone help me please?#include "main.h" #include "string.h" #include "stdio.h"   I2C_HandleTypeDef hi2c1; UART_HandleTypeDef huart2;...

How do i send multiplye bytes with HAL_I2C_Slave_Transmit in 1 try?

Im working on a project where I use the STM32L432 as slave while a Raspberry Pi is the master. The dataprotocol is I²c and im using the HAL_I2C library. But I cant transmit or receive data. Can someone help me with this?

I think i correctly setted up the slave adress on 0x70 with the configuration window.Below my script on the Raspberry Pi. #include "main.h" #include "string.h" #include "stdio.h"       I2C_HandleTypeDef hi2c1;   UART_HandleTypeDef huart2;     void Sy...
