This The I2C standard supports such multi-master configurations, and I wrote software for the ATmega several years ago that does this. This function is interrupt based and therefore I should have no problem completing the I2C request. I have a good record of data in Slave. Why is this? Below I have written a simple code. **Problem:** - When the I2C is enabled, the part can hit the WWDG. Before you include and set up the library as below, the I2S hardware peripheral has to be configured STM32 HAL_I2C_Master_Transmit - Why we need to shift address? 1.

HAL APIs are available for all peripherals. However, when i am running with freeRTOS this function is always returning me HAL_TIMEOUT. The problem is that UM1785 Description of STM32F0 HAL and low-layer drivers is a bit vague on explanations. And the code gets stuck in the HAL_I2C_IsDeviceReady function. If I would call HAL_I2C_* again while HAL_I2C_Mem_Read_DMA isn't finished I would expect it would be HAL_BUSY, but after several attempts (when HAL_I2C_Mem_Read_DMA finaly finishes) it would succeed with HAL_OK. – Low-layer APIs (LL) offering a fast light-weight expert-oriented layer which is closer to the hardware than the HAL.
