Hello,I'm writing this post because I'm facing an issue with generating a PWM signal on TIM3 for a buzzer application using the STM32L476RET microcontroller. Based on the buzzer's datasheet, it requires a 4,000 Hz square wave with a 50% duty cycle. I...
Hello,I'm using STM32H743 to send and receive REST API. I'm using FreeRTOS, LWIP and mbedTLS to communicate with server. I have the same application working WELL using STM32F765 with MCAL layer of course modified to STM32F7 but using H7 I can see thi...
Dear,We using an ADC in our application at 1MspsThe ADC is always running in a circular DMA mode.To start the buffering of the samples we use the Analog watchdog 1. So when the input signal goes outside the analog watchdog thresholds the function "HA...
Hey I am trying to use CMSIS DSP library to perform FFT of i2s data from a mic but it is showing error after using the FFT functions but is compling if only library is added is there any thing I have missed this is the code: /* USER CODE END Header *...
I want to implement a firmware upgrade feature. Currently, I am doing it as follows: on the M4 core, I have a bootloader and an application; on the M7 core, there is also a bootloader and an application. The M4 application is located at address 0x081...
I'm using AL94 library on STM32H7 for USB Composite functionality. The MSC class driver appears practically identical to 'native' MSC Class provided by STM.However, I am having difficulties running even the simple RAM disk example - the drive is corr...
Hello everyone and thank you for your help, I am being using the STM32F746G-Discovery Board for a couple of months first time working on it and I am currently working on a project where I want to transfer firmware to board which have a SD card on it,...
Hi,I would like to know if I can emulate the STM32H5 (which is ARM cortex-M33) via Qemu. And if so, are there any limitations in emulating different drivers, especially the ADC and PWM within FreeRTOS Kind RegardsHani Akeila
Hello, I was trying to use RTC battery backup on a nucleo F446RET6.The problem was that the battery (CR2032) connected to VBAT tries (and can't) to power all the board.Looking to schematic diagram, I see that VBAT pin is connected to VDD thru SB45.Re...
Hi, I'm using a STM32H7S78-DK board along with stm32cudeide 1.16.0. I'm loading the example LTDC_ColorKeyring which work fine, here is the issue... I'm trying to implement uart4 connected to the onboard ST-link. If I init MX_UART4_Init() and use HAL_...
