hiim using stm32g474vet6timer1 is trigger mode ,timer3 slavemode, both timer1 and 3 operate at 5khztimer1 will trigger timer3 and timer3 will trigger adc at every 5khz ,im using adc in multimode dma ,now the problem is when initally i start these con...
Hello teamI'm working on the LCD display parallel connection stm32f4 series.Please check the FSMC interface; I've included my schematic.
Hello, ST experts For some reason, PA12 of STM32U595VGT6 is set to GPIO at start up. But I can not find how to set PA12 to USB_DP again in any alternate function of AF1 to AF15. BRYang
Hi, I am experimenting with the STM32U5G9J-DK2 discovery kit and want to use one of the basic timers to regularly trigger a memory-to-peripheral DMA request to write different values into the GPIOD ODR register. I set up TIM7 to trigger about every 1...
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 ...
