I wanted to use the STM32F439 timers, any of them but timer 8 seems to be the best one with my current peripherals, to act as a trigger source. Basically, the timer would drive a pin low, and at specific counts of the timer, drive the pin high for ~5...
HI, my application is a tcp echoserver which works perfectly but, only for 10-20 minutes, after don't ping anymore. I'm using STM32H723 with LWIP and RTOS and I think it's a memory configuration issue. This is my setup: void MPU_Config(void) { MPU...
I recently have purchased a BME280 I2C sensor, which measures pressure, temperature, and humidity. I wanted to create a library for it to measure those variables. the problem is that the result (at least, the temperature measurement) is wrong.it thro...
I'm using a NUCLEO-H563ZI and the STM32 HAL (generated by CubeMX) and there's no data (and no activity) on any of the SPI lines.I'm using SPI2 and it is configured as follows: static void MX_SPI2_Init(void) { /* USER CODE BEGIN SPI2_Init 0 */ ...
I am experiencing an issue with the Dual Boot Bank Swap Boot Loader on my STM32G474RE microcontroller. I am able to run code for GPIO led Toggle in both flash memory banks by swapping the banks using SwitchBank function (executed once), but neither b...
Hi, in my current audio processing set up I have a CODEC set as master connected to my STM32F446RE (slave). The current configuration utilizes I2S DMA interrupt callbacks to handle the input and processing of these samples received. The CODEC receive...
Hello,As I enter debug mode and start to run (code execution), nothing is updating in the debug window( the t1 variable at the bottom of the debug mode window just showed me zero or .0026)However, my program works fine on my STM32F10x MCU. When I sto...
This post was originally attached to this old, solved thread: https://community.st.com/t5/stm32-mcus-products/how-to-reset-counter-value/td-p/175202 Hi, in my case this technique has some drowback. It seems that using the macro __HAL_TIM_SET_CO...
Hello everyone,I am currently working on a bootloader project for the STM32H735, using the pre-configured ExtMem_Boot project provided by the STM32CubeIDE. However, I am encountering an issue when trying to write to the external flash memory at addre...
I'm considering using the internal PLL to generate a clock for a precision ADC. My sample rate is low, so it's possible this may work. I need less than 50 ps RMS phase period jitter.Looking in the datasheet at the specs for PLL1, I'm having difficult...
