Problem: During HALL_Init(), when executing macro __HAL_RCC_SYSCFG_CLK_ENABLE() the interrupt vector table is overwriten w/ garbage.At first interrupt generated by TimeBase (SysTicks) debugger gets a SIGTRAP @ 0x1fff3744 outside of program code. Int...
STM32F407There are only two lines in the code that I wrote.HAL_TIM_PWM_Start(&htim4, TIM_CHANNEL_2);TIM4->CCR2=3;The pin is activated when the number in the CNT register and the CCR2 register match.The pin is deactivated at the end of counting in the...
Hello,I am trying to set up a CAN Data Frame receive interruption on a STM32F0-DISCOVERY board. The interruption seems to jump for all other IER register elements, but not for the RX. Stopping the processor execution on debug and checking the status ...
Hi!I am working on a project with stm32h757 and soon we will be switching to stm32h747. i need a way to know (using SW) on which processor i am working with.is there some type of register that holds this info?I saw the 96b UID but as i understad it ...
hey,i am new to stm, recently i was asked to transmit data from uart based on dma instead of using interrupts that uses the cpu resources.are there examples or instruction of how to do it? i am searching for 2 days and cant find somthing usefull.
Hello Everyone,For some reason my STM32F407 MCU with specific board has problematic issues in the start. If I connect 3 different cards to its UART channels, which utilizes DMA, it does not start directly and after a while (which corresponds to 1 sec...
I know TrueSTUDIO is tagged as obsolete, but I like to use it.The STM32H5 use Cortex-M33 core, then how to add M33 support?I already upgraded TrueSTUDIO to support GCC 10.3.1 and recent loaders and SVD files. It would be nice to use M33 cores with Tr...
Hello everybody,I am trying to bit-bang an I2S interface on an STM32F103 at 72MHz using TIM2.Am I way too optimistic to get a 3MHz "clock" out on a pin? The fastest I can seem to get it is at 90kHz.I have set the "prescaler" of TIM2 to "0" and "1".An...
Sir I am doing my final year project and got struck. My project aim is to receive data from the nrf24l01 module which connected with arduino for generating sinewaves this act as TX part. Now in RX part I am using nrf24l01 with STM32f411re and I want ...
