I am asking a question of application rather than capabilities of MCU itself.I hope to build an handheld board that is powered by batteries and using this board update other board's settings, especially date/time configurations.This requires a parser...
Hi all,I am currently designing a board based around the STM32F303xC MCU, and had a few questions regarding information on the datasheet.- For boot modes, the data sheet states the following:"At startup, Boot0 pin and Boot1 option bit are used to sel...
We have a new board that uses the STM32H747 MCU and is based on an existing, proven design.Despite being schematically identical, the MCU on the new board cannot be detected by the STLINK-V3SET programmer and STM32Cube software. For whatever reason, ...
Hi everyone, I'm new to STM32. I'm trying to use the STM32C011x4's internal temperature sensor.I'm doing the same as the website below:https://deepbluembedded.com/stm32-internal-temperature-sensor-reading-example/#:~:text=The%20STM32%20microcontrolle...
Hello, I am configuring a PWM Timer and I would like it to by triggered by ETR, the PWM is a 99 period, 50 duty cycles, with auto reload enable. I would like to have the PWM to be restarted (resync in a sort) at each etr rising pulse. ETR Pulse does ...
Hello , am using stm32f411 nucleo board. uint32_t sin_table[2] = {150, 250, 100}HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *)sin_table, 3)HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_2, (uint32_t *)sin_table, 3);I am giving this value to t...
Hi.I use a trigger source to trigger SPI tx/rx linked-list DMA (not circular). But have no clues how to jude if the tx/rx DMA is done. I traced the IRQ handler, it calls, the code below: /** * @brief DMA SPI transmit receive process complete c...
Any suggestions as to why power down, then reconnect debugger (JLINK pro) is clearing the TAMP registers to 0?Device is STM32L4P5The clock source seems to be present, it doesn't enter the if statement if (LL_RCC_GetRTCClockSource() != LL_RCC_RTC...
I'm working with the STM32U575 and using all four i2c blocks. My i2c code is interrupt driven.I can't find the right way to check which i2c block trigered the interrupt, suggestions please? void HAL_I2C_AddrCallback(I2C_HandleTypeDef *hi2c, uint8_t d...
I followed this tutorial and I'm able to transmit UDP packets from my nucleo board to my computer. I've configured the code to use lwIP without freeRTOS. I'm trying to receive packets on my board over Ethernet by setting up a callback and it never en...
