Hello guys!I am working on STM32F042K6T6 microcontroller So we are facing CAN communication problem in the above mentioned controller.The problem is that the data is not been able to receive though i am sending from other controller and the CAN trans...
Hello,i would like to roughly estimate the time the processor needs to execute some pieces of code.I know there is the DWT Cyclecounter, but the values it shows vary from one time to another at the same instruction. Also there is no information from ...
My program writes to flash but needs to know if it has been run before since the chip was re-programmed. I've set up a section in the flash memory that gets written to by the programFLASH2 (rx) : ORIGIN = 0x08100000, LENGTH = 1024K .option : ...
Hello,I need to count the number of (positive and negative) edges in a signal within certain time period. For that I use a timer on STM32L452. The AN4776 says that External Clock Mode 1 is able to update the counter on both edges (for the price of no...
Hi,In the cases below I try to read value of an SRAM address which is in TIM2_IRQHandler(), from main() function or user Program() function, but no result!anyone who is experienced or has idea?void Program(); void TIM2_IRQHandler() { if(__HAL_TIM_...
I just saw Power on reset feature in Pic (https://microchipdeveloper.com/8bit:por). It can hold mcu a little bit until the power is stable, before starting the hardware initialization. I would like to know if this feature is avalilable on stm32.I ha...
HelloI've been working on a project on an nucleo F411RE and everythings been going fine.I then had to port the project to nucleo H743ZI.As i am using the DMA i had to change the ram from DTCRAM to RAM_D1.Before the change to RAM_D1 i could have strin...
We are developing the TouchGFX project in STM32F746BGT6 and using resistive TouchscreenWe have created the project using ST CUBEMX for discovery board .the same project code has been used for our customized PCB.For this we need to interface the STMP...
I am testing EXTI interrupts on STM32F103 board. The device works properly when soft reset is given. Interrupts are triggered properly. But when I give hard rest to the device(Like power off & power on) , it fails to initialize STM32. Maybe it gets a...
