Resolved! Tricky GPIO Input bug in Nucleo STM32F4 bare metal project
Hi, I at a high level I have designed a program to toggle the user LED on PA5 if a gpio input sees a high signal (shorter than 150ms) on PA0. The program works well most of the time except in some instances when it will miss an input pulse entire...
STLink to MIPI10 cable?
A web search tells me I have a problem! My STM32 target has a MIPI10 connection for SWD debugging which works great with my I-jet probe. I now need to use an STLink but none of the supplied cables are for a MIPI10 target. Where can I buy such a cable...
Smoke came out of the MPU and when I connect it to the computer, the power light is on, but the usb device is not recognized.
I connected the 5v input of usb-ttl to the 5v output of the MPU, while the mpu was plugged into the computer and suddenly smoke came out. Now I get 2.8V from the 5v output of the MPU, 2.5v from the 3v output. Also in the debug circuit, r4,r10,r11,r14...
Resolved! What is the white plastic debugger connector of STM32C0316-DK?
The white plastic clip on the board for ST-LINK3-MINIE debugger:https://www.st.com/en/evaluation-tools/stm32c0316-dk.htmlIs it available to order separately? For different board thickness?
Resolved! Unable to flash STM32G031 (8 pins) with STM32CubeProgrammer & ST-LINK/V2.
I've have a custom board with a STM32G031,from the board we have access to the following MCU pins:+3V3_BTNRSTBTSWDIOSWCLK_USARTTXI've connected this 4 pins to a ST-LINK/V2. Like this (left) mcu, (right) st-link.+3V3_BT --> VCCNRSTBT --> NRSTSWDIO -->...
Hello everyone, I'm having a problem with my 2 of STM32H745I-DISCO boards. Code could not come to main while(1).
I saw the problem when I use them for a basic LED Blink code. The Code got stuck in a while loop in SystemClock_Config() function. I tried lots of things.My __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1) will not return to SystemClock_...
The microcontroller (STM32G0 Series) does not work after FLASH read protection.
I am using stm32g030f6p9 microcontroller. I tried to make flash read protection: if ((FLASH->OPTR & FLASH_OPTR_RDP) != 0xbb) { FLASH->KEYR = 0x45670123; FLASH->KEYR = 0xCDEF89AB; while (FLASH->SR & FLASH_SR_BSY1); FLASH->...
Stlink V3 with Firmware V3J10 on Raspberry not working anymore. With V3J7 yes.
Hi there. I'm new here.I've a great Problem. I have a Raspberry 4 B and I've plugged inthe stlink v3 for flashing my STM32 Board. I've installed some missinglibraries and also pystlink with pyUSB and stlink. There was no problems.On the programmer I ...
Conformal Coating STM32L431CCY6TR
Hi TeamWe are currently working on ST MCU PN: STM32L431CCY6TR in our new project. Thus, I would like to check with ST whether this part is OK to be Conformal coated? The reason is, our PCB will need to be conformal coating after all the components ar...
