I’m working on a project that uses an STM32H745IIK6. Occasionally, 32-bit SPI read data was invalid. This happened in about one out of every two hundred reads. To track down the cause, I added a few lines of code to toggle a GPIO pin as a scope trigg...
I encountered this error when configuring I2C2 on H7A3 board, fast mode, i2c enabled, and code auto generated from ioc. anyone can kindly advise? MX_I2C2_Init used but never define
Using STM32CubeIDE (1.13.1) and STM32L476RG Nucleo board.The MainApp code has modified start address 0x08008000 via linker file and system_stm32l4xx.c file so VTOC point to interrupt vector from 0x08008000 with start code from 0x08008190. Under the d...
I am currently working on a project where I need to create a C++ program for my PC that simplifies the firmware update process for an STM32F722 microcontroller. I have successfully placed the microcontroller in bootloader mode, which comes preloaded ...
Hello, I am doing UART communication with DMA in my project. When the communication first starts, there is no problem, but after about 10 minutes, the receive process ends. Can you check my codes?volatile uint8_t txdata[8];char rxdata[8]={'*','*','*'...
Hello! I am using the RTC of a STM32L412 with 32kHz LSI to wake the MCU from STOP2 mode after a specified time in seconds. Now I´m having two issues:1) I cannot program the MCU using a ST-Link V2 with current Firmware, when the STOP2 mode is active. ...
Hello team,We are looking to generate a sine function of 50 Hz frequency using the STM Cordic.Can you please share the theta range in this case. While we are giving 0 to 1 or 0 to 2pi (normal theta range), the resulting sine wave is not as per expect...
I'm fairly new to low-power and sleep-mode applications of STM32H7 microcontrollers. I've been trying to read through the documentation, but I'm having trouble getting a whole picture idea of how this works, and connecting all the information from th...
I'm using an STM32G473 on a custom board. The board is connected to battery pack and once assembled the MCU is permanently connected to 3V3. We're using STANDBY to put the MCU in a low power consumption state while the system is turned off. My proble...
I'm working on an application that requires a very fast UART speed. The STM32H7 allows a UART speed of 17 Mbps, which is just barely enough, but should work. However, other than the fast UART speed, I don't need to do a lot of processing. I would hav...
