I am having a strange (to me) issues trying to program an STM32H743VI.I have had the PCB manufactured and assembled by a different supplier and all of a sudden I cannot program the STM32H743....I do not have the NRST pin back to the STLink-V2, only t...
I have a custom designed board using a STM32F429IET6 and LAN8742A.While attempting to bring-up ethernet and LWIP (fails w/o LWIP at the same spot) the code continuously fails in stm32f4xx_hal_eth.c in `HAL_ETH_Init` while waiting for the SW reset to ...
We are generating PWM using the STM32F429 TIM10 -- In this call-back function we counting the PWM pulses and , when counting pulse is equal to the total pulse then stop the PWM.But in this code counter are counting the properly counting the pulses bu...
I am using st-flash version of 1.8.0 to flash the binary into Nucleo H563ZI. In this process i have used erase command "st-flash --connect-under-reset erase" to check whether the hardware works or not. For the erase command i got below error"st-flash...
Hello I need to send a string via USART every 500ms. I tried to use DMA that seems to be easy to configure. USART transfer works but only without DMA (test in while main cycle). I do not see any problem in DMA configuration. Can you tell me it there ...
Hi , I tested example " I3C_Controller_Private_Command_IT " with Controller H503RB board and modified for JEDEC SMBUS for DDR5 ( JEDEC smbus is more simple than MIPI I3C ,No DynAddrAssign function , Initially I2C after CCC SetAASA , it ...
Greetings Everybody, I have Nucleo - F207ZG board. I have attached external 3.0 V coin battery to VBat and GND. I am configuring board for RTC peripheral. After configuring RTC time and again rechecking after 1 day the time starts to move ahead or ti...
I am using two quadrature encoders through the STM32F411CEU6 timer encoder mode. Here is the graph for one of their CNT values:As you can see, it takes about 400ms to update the value, but when it does, it seems accurate. How can I make it so that it...
Posted on April 26, 2018 at 09:34Hello all. My problem is as follows.I would like to set an event in the future, lets say 950ms, at one specific point in the code. Then I would like to set the STM32L432 in Stop2 mode, wake up the MCU near the event,...
Hello guys !I am new at the embedded systems and I am trying figure it out ! I am using STM32F446VET7.I connected my buzzer to an GPIO pin(PB12) which has no pwm speciliaties.But my buzzer is not working when I connected to the DC signal source like ...
