I would like read the gpio lines at fastest speed. As example it is possible to read first 4 ports by reading:uint16_t ports0123=GPIOC->IDR&0x000F; (it is very fast, takes 28 tics)It is possible to read ports GPIO_PIN_0-15 by connecting GPIOC->IDR to...
Hi everybody, Actually I start a new project with a ST7567 driver for LCD 128x64. I have create my project with CubeIDE . CubeIDE generate my code in the main.c like this : /* Private variables ----------------------------------------------------...
HI!I am trying to program a custom STM32F446 Board using the SWD connections on the board. When trying to flash the custom board I receive the following error on OpenOcd: xPack Open On-Chip Debugger 0.12.0+dev-01312-g18281b0c4-dirty (2023-09-04-22:...
Hi,I started working on STM32C011J4.Systick, PWM, ADC, GPIO works just fine. Set pin4 to NRST_MODE 2 via STM32CubeProgrammer (v2.15.0) as GPIO. MCU gets stuck at reset if pin4 is low at power on reset. After applying 1.4V or higher to it momentarily ...
Hi supporter,I'm developing STM32H573I-DK and trying HAL_ETH_ReadPHYRegister to check link status. But this API seems be changed.Previous prototype is:HAL_StatusTypeDef HAL_ETH_ReadPHYRegister(ETH_HandleTypeDef *heth, uint16_t PHYReg, uint32_t *RegVa...
I'm using the HAL drivers to configure ADC1 Channel 3 as Differential and Channel 4 as Single Ended.According to the reference manual (Figure 143) when ADC1 Channel 3 is differential, it is Channel 7 that becomes unavailable as it is used as INN3. T...
Hi, I'm working on a project for wildlife surveying, the project details are that we need to have a camera surveying an area where it will capture an image every 10s, then store data on an SD card. The system will be running for 2 weeks, and idle whe...
I want to output a static DC value from an STM32G473 DAC, but I’m seeing the output value has a noise tone on it that changes amplitude and frequency depending on various other settings. The behavior reproduces with all other peripherals disabled. H...
We have a design based on the STM32G0B1CET6 MCU.Recently we noticed some failing parts after power on/off testing. Symptoms: software is no longer running and the SWD port is not responding. We sent the broken parts to ST for analysis. The report (C2...
We have a custom board prototype with a STM32H730VBT6 (LQFP100 package) and a SPI NOR flash memory.Sadly, this not connected to the OCTOSPIM_P1 port, but to the SPI1_NSS, SPI1_SCK, SPI1_MISO, SPI1_MISO (PA4, PA5, PA6, PB5) port (so, ony 2 data lines ...
