Hello!I have a new project with a STM32F407VET6 and a STM32F103xxx over a RJ45 Jack with I2C.i worked a lot of time with I2C EEPROMs and it works fine, but my communication between the 2 STM's are horrible, or i am too confused.i found the tutorial o...

Hello,I am not really new, but i have a courious problem.I have a STM32F103CBU6 device (new), and started a new C++ Project with STM32CubeIDE 1.13.2 and the STM32Cube FW_F1 V1.8.5 firmware package.I have a external crystal for both (HSE + LSE) and is...

Hello,I have a problem with my default code (generated by Stm32CubeIDE), I use a STM32F723ZG with Ethernet.I started a new project, with default settings, this works fine, now I enable ETH and LWIP with DCache, it works fine... now, I enable FreeRTOS...

Hey,my EEPROM works fine...I have the "standard" pull-ups with 4k7 on my circuit and 3.3V.. many poeples say thats to high for 3.3v?

Thank you, it's complicated with 7-Bit and 8-Bit Addresses...But now it works. 

Thanks,But the code doesn't work, or my slave is *** ?heres my master code:void i2c_function(void) { i2c_scanner(); uint8_t slave = 0x12; char *data = "Test"; if(HAL_I2C_Transmit_IT(&hi2c2, (uint8_t*) data, (uint16_t) slave<<1, sizeof(data)) ...

Hello,Thanks for the Tip with sizeof()...Hm, the Buffer has a size of 64, when buffer is full, the interrupt is fired, but the problem is, the IRQ Handler Runs in Error 0x08 (HAL_UART_ERROR_ORE).But why runs the IRQ handler in the overrun? my test m...
