Hi,I'm attempting to write to an SD Card using a Riverdi STM32U5A9 display board. Since TouchGFX natively uses FreeRTOS, I'm attempting to keep it within FreeRTOS. Porting to ThreadX has caused it's own issues which I have in a separate thread. In...
I call HAL_UART_Init() with LPUART1 at 20Mbaud but when I activate assertion it fail at IS_UART_BAUDRATE().The IS_UART_BAUDRATE() is not correct for LPUART that can have a baudrate up to 53.3 Mbaud.Also for UART, the comparaison in IS_UART_BAUDRATE()...
Can somebody please help me. The code below is initializing the RTC. The clock works I can set and read time and date no problem. Somehow if I change these register: hrtc.Init.AsynchPrediv = 131; hrtc.Init.SynchPrediv = 10; It has no imp...
Hi, I am trying to configure my STM32G071GBU6 to enable reprogramming the flash throguh USART1. I check the datasheet of STM32G071x8/xB, reference manual RM0444, and application note AN2026. It says I am supposed to configure the PA9 (USART1_Tx) and...
We're using the following circuit to measure a battery voltage @ 20 kHz for use in motor control.We are having some issues though, where the ADC suddenly starts measuring 0 V (0 in the data register) and gets locked in this state. In this state, we a...
Hi,We have a weired problem with a custom N657 design.When using the Nucleo board, its possible to flash the program on the external flash, as long as BOOT1=1.The programmer resets the board and it flashes the firmware normally every time.On our boar...
Hello everyone, Some time ago I asked on this website information about jitter on a PWM : Solved: PWM jitter - STMicroelectronics CommunityThe problem was that when generating a PWM, it wasn't very stable. At the time changing the source clock to the...
I recently purchased some STMF303 boards for implementing a free pre-compiled HEX file.I received the boards with the STM32F303CCT6 chip, but the pre-compiled file was for the STM32F303CBT6 chip. The HEX loads but does not run on any 303CCT6.Are ther...
Hey!I will explain my setup and then paste the code. I have three different timers (TIM1, TIM2, TIM3) sending out PWMs to different parts of my board. All timers are set up the same way; the only difference is that TIM1 is an advanced timer.What I do...
Hello everyone,This is my first post on the platform, so please bear with me.I would like to write raw data to an SD card very quickly.After quite a bit of research, I decided to use SDMMC with MDMA, and I want to write directly to the SD card blocks...
