Using STM32CubeMX (v6.12.1) with USB_OTG_HS enabled (as host) on an STM32F4.On our device, we have the only OTG_HS_VBUS pin connected to the USB VBUS, and it is working correctly as a USB host. I was investigating if I can repurpose this pin (I guess...
Hello,I need to use a nRST pin as MCO in my aplication and programm my STM with STlink v3-set. I set up a MCO to output 8MHz signal and set nRST pin to GPIO with code you can see bellow. Now I have a problem with booting - I cannot connect to STM, Cu...
We purchased 403pcs MCUs (STM32F401VBH3) with date code 314 from Mouser website, as shown in the picture below, they have been assembled on the board, When preparing to program them with ST-LINK utility and the programmer (ST-LINK/V2), I found that ...
I am using the B-L072Z-LRWAN1 and trying to code LPTIM with interrupts and no HAL. The code seems to be getting stuck in the Infinite_Loop section in the startup.s file. The comments around this loop say that an unexpected interrupt was triggered. If...
Hi,I have a question regarding the implementation of the Qt framework for the STM32H747I-DISCO board. While browsing the Qt website, I noticed an example for the similar STM32H750B-DK board, but I couldn’t find any information specific to the DISCO m...
Hal_Delay çalışmayı durdurdu ( STM32F030C6T6 )Forumda buna benzer birçok konu okudum ama bir çözüm bulamadım. Sanırım sorunun kaynağının bu olduğunu anlayalı 7-8 gün oldu. Hal_Delay() çalışmadığı için GetTick() fonksiyonunu da kullanamıyorum. Basit t...
Hello, I am trying to receive and transmit byte-to-byte on a STM32F429 Discovery, I will be using a STM32U5 Discovery soon. I used UART IT method but maybe there is a better solution...Objective & Issue:I want to continuously receive and send byte-to...
Hi,is there anyway to insert a delay between the start generation address byte transmission and the first data byte reception from the slave device? I have tried reading 0 bytes from the slave to prevent the reading of the first byte but that sets th...
Hi there,I want to clear the specified flash page's WRP by program, but I can only do it by clearing all the flash page's WRP,meanwhile, I also need to keep my data in option byte.my code is as follows(the project at HERE :(uint8_t data0 = HAL_FLASHE...
Hi there,There is a config option named "OB_STOP_RST" that exists in Option Bytes' USERconfig, I tested it with STOP mode, and it works well.But I can't understand when we should use it. After clearing this bit to OB_STOP_RST, the MCU will reset righ...
