STM32U585x UART Poll receive is happening only for first byte :
Dear CommunityI have a problem with the UART1 on the STM32U585x board. I try to read some bytes in polling mode using HAL_UART_Receive();And i set the size parameter to any number greater than 1 and i only receive 1 byte, even though i am sending mor...
Resolved! Interfacing STM32F429VIT6 with TFT LCD display without using external RAM
Hi ST community, Recently i am working on a project, home automation, and i would like to use STM32F429VIT6 MCU and 3.5 inch 320RGB x 480 LCD display on the project. The LCD display controller is ST7365P from Sitronix, with Frame Memory Size: 320 x 4...
Resolved! Bootloader and Read-while-write (RWW)
Hello,we are using a STM32F429.The bootloader is located in the first 64kB. The firmware in the remaining sectors.It erases the remaining sectors of the flash and writes the new firmware.Now, 3.6.5 Read-while-write (RWW) of the reference manual state...
USING A GPIO PIN TO TAKE INPUT OF A PWM SIGNAL FOR MEASURING DUTY CYCLE AND FREQUENCY
I have a stm32g031k8 board. I was trying to give a pwm input signal like a square wave, measuring the frequency and duty cycle and generate pwm signal of that frequency and duty cycle using another timer. I was also changing the frequency and duty cy...
HSE or LSE for my specific MCU application ?
Hi.I was searching for a crystal that meets the requiremets for the HSE of the MCU I´m using (STM32L4P5RGT6) at the beginning I tried to make the corresponding calcuations by myself but after researching I noticed that for some calculation I needed m...
Resolved! stm32f1 bootloader write memory command
Hello,i'm trying to implement firmware upgrade in my Windows application via USART for stm32f103 following AN3155. My issue is with the Write Command. More specifically:- if i send 1 byte of user data at time it works, it's just slow cause i have to ...
Timing of Hardware Semaphore
We're using a STM32H747IGT6 and using hardware semaphores to coordinate between the two cores.On the CM4 I've set up TIMER3 to run at full blast: LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM3); LL_TIM_SetPrescaler(TIM3, 0); // Count at sy...
BOOT0 on STM32U083
I have a custom board with an STM32U083KCU6 MCU - see schematics belowVBAT = +3.6VI have 2 boards:1. board: I flashed it via SWD but forgot to enable it in STM32CubeMX, which means that I'm not able to flash it again via SWD2. Board: This time, I rem...
On STM32H747IGT6, HSEM channel 0 is reserved?
Application note AN5361 "Setting up with ST-LINK GDB server" says "Set the Cortex®-M7 core running so that the HSEM semaphore is released and Cortex®-M4 wakes up from Stop mode" and this post implies that it's "HSEM 0" which I'm assuming is HSEM chan...
