I'm running into an issue on two boards (an STM32H735 Discovery Kit) and a custom board with an H743. #include <stdio.h> #include <zephyr/kernel.h> int main(void) { while (1) { printf("Hello there, world!\n"); k_msleep(1000); } return 0; }If ...
Hello everyone, I’m using an STM32L412K8 microcontroller with an external 32.768 kHz LSE crystal to operate the RTC for real-time clock functionality. However, I'm facing two issues: Second jumps: the seconds skip multiple values out of order (for ex...
Hello.I am finishing a project where I measure voltage with an ADC using the STM32L431 and, for greater accuracy, I am using the OPAMP (PA0 = ADC1_IN0_VINP and PA3 = ADC1_IN_VOUT). For the STM32L431 on the STM32CubeMX, when activating the OPAMP in "F...
MCU: STM32H753XIH Tool: STM32CubeIDE v1.18.1 FW Pkg: FW_H7_V1.12.1 I have an in-house designed board that has an FPGA connected to the FMC bus. The FPGA uses a simple SRAM interface with Address (7:0), Data (31:0), Chip Select, Rea...
Any step-by-step guide on how to configure STM32CubeIDE to redirect `printf()` output to a virtual COM port using UART (serial communication), and then monitor that output using the STM32CubeIDE’s built-in Terminal view? I'm using a Nucleo-F411Re on...
Hello everyoneI am a begineer with stm32 MCUs. I studied through youtube videos and datasheets that we can program STM32H750 using STlink V3 and to do so the MCU should be put into bootloader first. To do so the boot pin must be pulled low for which...
Hello World;My Setup:Nucleo F767ZI BoardBOOT0 pulled highSCL/SDA on PB6/PB9 connected to Raspberry Pi I2C-1 and Saleae Logic Pro 8Nucleo board powered via USB from Raspberry PiGoal: Using ROM Bootloader over I2C for firmware updates (later on custom ...
Hello,I’m working on a custom board based on the STM32H753IITx and I'm trying to access a microSD card via USB_OTG_HS using the USB Mass Storage Class (MSC). I've read this post, which is close to my use case, but unfortunately, I haven’t been able t...
Hello,Using RS485 for modbus communication.It is observed that, if we disable STOP2 mode then RS485 communication works fine (no frame loss). but asa we keep STOP2 mode then at the time of wakeup I found some frame loss.#define RS485_TX_ENABLE() HA...
Hello everyone,I'm currently working on a UART communication protocol using STM32 USART in multiprocessor mode (MME / Address Mark) over RS485. My goal is to receive variable-length data frames only when the address matches, and use DMA + IDLE interr...
