We for testing CEC client device require emulate master. In normal device code we set hcec.Init.OwnAddress = CEC_OWN_ADDRESS_x but for TV master how is right choice? hcec.Init.OwnAddress = CEC_OWN_ADDRESS_NONE; or hcec.Init.OwnAddress = CEC_OWN_ADDR...
Hi I am using CAN in STM32F303RDT6.I am using HAL_CAN_AddTxMessage for CAN transmission.This function will send the data and return HAL_OK if the sending mailbox is free.However, although HAL_CAN_AddTxMessage returns HAL_OK, no message may actually b...
Hey together,I discovered a super strange a critical behaviour of the STM32H750 chip. Maybe you can help me to prove this issue. We have a firmware which is split into 2 parts (bootloader, application). Both BL and APP are using the UARTs to communic...
Hello,We are migrating to zephyr, the board which is supported by zephyr is nucleo_g0b1re, but out actual controller is stm32g0c1ret3. Both are of same family, have same memory and all. I have just made changes in the overlay file for my application,...
We are trying to do SPI communication in the GPIO interrupt handler.We are not sure about the following two points. Can someone please give me an answer?1, If another GPIO interrupt occurs while the GPIO interrupt handler is running (with the same pr...
We are developing a software application that uses GPIO interrupts.We want to set interrupts on the same pins (PE8, PG8), but only one of them can be set to external interrupt mode in the ioc.Is it not possible to set external interrupt mode for two ...
Hello All,I am using USART peripheral to transfer a block of bytes. I am trying to do it using DMA. Because I want all bytes of USART frame should be dispatched without any gaps between them and my system has few interrupts that could bring gaps bet...
Hi, We want to implement a USB-C functionality to our customized board (based on a STM32U5G9). The software uses FreeRTOS environnement. Is there an existing USB (Device) example, tutorial or library that could be compatible with our project?regard...
In MX, at first, I changed the sample rate to 8 bits to double the baudrate. The code was successfully generated, compiled and downloaded. The communication still exists, but the baudrate is still the same as before, with a bit duration of 1.08us.The...
Hi I am having some issues where my MCU ( stm32f030C8T6 ) seems to get stuck in a while loop when using I2C1 and a AS5600 IC.I will paste the code below but give some more detail on the issue here.In the function named "void I2C1_Write_DMA(uint8_t sl...
