Hey Everyone, I am having an issue with the stm32h755 dual debugging. Im trying to run cm4 by itself without cm7. But the issue im having is, whenever I reset the MCU and check the SPI lines, I see a clock running. When I debug just cm4, I do not se...
It is not recognized as a USB device. What did I do wrong or miss?IC: STM32F103CBT6 1. Is the distance between USB D+ and PA12 (Pin 33) and USB D- and PA11 (Pin 32) long?The distance from USB D+ to PA12 and USB D- to PA11 is approximately 35 mm (1,38...
Hi,i am trying to investigate the behaviour of the ADC when measuring a value, where the ADC is triggered from a timer source.In the manual it states, that when the ADC is clocked from SYSCLK or PLL "P", then it would be faster, but when clocked from...
Hello,Hope you all doing well..!! I am using two microcontrollers i.e., for transmitting data I have to use STM32F407VET6 and for receiving I have to use STM32F407VGT6 also I have to connect MCP2551 CAN Transceiver. I am transmitting data from one bo...
Salut la communauté, J'ai créé une carte électronique permettant de visualiser l'état de la batterie d'un ULM. J'ai utilisé le microcontrôleur STM32F401CD, et j'avais initialement prévu d'utiliser uniquement l'horloge interne HSI du MCU, donc je n'ai...
Hello everyone,I have been using for a long time the stm32L496ZGT6 in a customized PCB with an uSD card module. Never had any problem interfacing the card. Due to the shortage of supply during the pandemic situation I bought a couple of stm32L552ZET6...
I am starting some test with this modulehttps://it.aliexpress.com/item/1005002482177244.htmlwith 7” lcdI have found only one example that run but with TouchgfxI have got the same ioc from this example to generate a new code and insert the functions t...
Hello!I'm using Comparator 1 in the STM32f071rbt6 uC. The Comp is properly configured, and sends an interrupt once triggered on PA1 referenced to PA4(DAC_OUT_1).it happened that the PA1 GPIO accidentally was not configured. Yet the comparator functi...
I bought a NUCLEO H755ZI board, but I can't make the LED connected to GPIOB pin 14 blink, neither with CMSIS nor with HAL, I saw some tutorials and questions here, but nothing solved it, thank you in advance for your help.
