Hello,my CPU is a STM32H745. I want to flash data into both banks (bank 1, sector 2-7, complete bank 2, while the code runs from the first bank, sector 0+1.I'm using the given HAL-drivers stm32h7xx_hal_flash.c and stm32h7xx_hal_flash_ex.c and found a...
Hi! Hope everyone are doing well! I currently encounter a problem and can't solve it. I want to write some pieces of data into a file in a usb-disk and now the Appli_state is constantly idle even I connect the USB-Disk already.This is a test demo cod...
I am using a STM32L471 MCU in a design that may be flashed with new firmware in situ. I'm using SWD as the interface, so the two unneeded JTAG pins (JTDI and JTDO) are used for other purposes. According to the reference manual, JTAG is activated by d...
Hi everyone Question: suppose one sets up a DMA transfer from a Timer1 register to memory so that it gets executed when timer event is raised. What happens first:the peripheral to memory DMA transfer is executed ?or the Timer registers are updated?...
I am reaching out to seek your expertise regarding the DMA transfer issue on SPI that I encountered while using the STM32H743 microcontroller.When an EXTI LINE 0 event (data ready) occurs, attached to the code is a program in which 30 bytes of 0xFF ...
ILI9341 display connected to STM32F407VGT6The USB drive is connected to the STM32F407VGT6, this USB drive contains images, I need to send these images to the display. I already know how to send to the display an array that is located on a USB drive....
Hi everyone,I am using STM32F407 to read voltage and current values from INA232 and TCA9548.I have 8 INA232 so I used TCA9548 as I2C Switch.I have coded as follows:1. SET TCA9548 on Port 12. Read the voltage value on INA232 at port 1The result I get ...
STM32F407ZGT6STM32F407ZGT6JWhat does the J suffix stand for?No explanation was found in the datasheet
Hi , I am trying to calibrate ADC in STM32334R8. But the code is stoping at calibration phase itself. I will attach the initilization code below for your reference. LL_ADC_Disable(ADC1);LL_GPIO_ResetOutputPin(GPIOC,LL_GPIO_PIN_8);LL_ADC_EnableIntern...
Hi, I just decided to try mbed OS 6 for programming my NUCLEO-WB15CC. Compilation is successful, but when i try to flash the compiled .bin file, the operation fails saying that a device was not connected even though it was. I am guessing it is becaus...
