About using virtual com ports with STM32F767
Hello!Before I forget, I'm using STM32IDE 1.6.1 on Linux. The board is a custom design. In order to make the problem reproductible, I have reproduced the problem on a Nucleo 144 board with STM32F767.I have setup a VCOM port using USB cdc, and it work...
Resolved! SDRAM reverting to 0x0000 for all locations when halting with debugger STM32F429
Hi,I've run into a problem that's a bit puzzling for me: I'm trying to get SDRAM to work on my board. The Hardware is based on the STM32F429 Discovery-Board, but has the SDRAM connected to Bank 1, a NAND-Flash connected to Bank 2 and the ILI9341 LCD ...
Id hardware in OTP STM32f207
Hi everyone!I am using 1 piece of hardware that uses an STM32f207igh6 that has a registration number on it (serial). However, every time the STM32 f207 chip is damaged, it is necessary to replace the chip with a new one, so that the registration num...
Endian problem on STM32 reading Flash
I am reading 64bit values from flash uint64_t DATA_read = *(__IO uint64_t *)0x0801E010;Where THE FLASH ADDERSS 0x0801E010 contains 5A5A5A5A 00440040DATA_read value afer this read is 0x400044005a5a5a5aif I read uint64_t DATA_read = *(__IO uint64_t *)...
How to get data from a fixed address after startup？
I want to take out the data I need from a certain address after startup, I created an array inside tf-a ( char array [0x200] = {}) , and I read the address of the array printf("%p", (void*) &array), which seems to never be repeated after many...
F042 ADC DMA malfunction:?? I am using a Nucleo_F042k board but will target a F042F MCU later. I'm using DMA to set up 2 ADC channels + the 3 internal ADC values. Results : 1: 2146: 2: 1668: 3: 0: 4: 0: 5: 0. Only the first is verifiable.
I have probably missed something simple. I use CubeMx to Configure the A2D channels hadc.Instance = ADC1; hadc.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV1; hadc.Init.Resolution = ADC_RESOLUTION_12B; hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT; ...
about dominant error
Dear Guys I get the "bit dominant error" when programming for can with STM32F302. even i set CAN_MODE_SILENT_LOOPBACK mode , also get this error after exec the statement "SET_BIT(hcan->Instance->sTxMailBox[transmitmailbox].TIR, CAN_TI0R_TXRQ);" a...
How to DMA transfer ADC value to D-cache of STM32H7?
Regarding the title, please show me the initialization code. I have a NUCLEO-H723 and a Discovery H735G-DK. Thank you.
STM32(F4) Timers - many different varieties, with different features and functionality. Very hard to understand from the datasheet which to use for what, timing, pwm output, external pulse counter etc. Any clear guidance to be found?
I had an application that demanded input counter mode, and the four timers I picked (10, 11, 13, 14) turned out to be unable to perform this function.
