Good dayI am using a NUCLEO-STMG0B1RE board and i am trying to handle a 4x3 matrix keypad inputs using interrupts to switch menus on an OLED screen. The keypad inputs worked when I used continuous polling for keypad inputs. The OLED needs to continuo...
i need to develop a custom HID device, where I can be able to control the LEDS using HID. the user can control using PYTHON OR GUI please provide me the code i am using NUCLEO-H723ZG
I want to connect my STM32H573I-DK to Azure IoT Hub via MQTT over websocket to avoid firewall complications.For that I am using STM32CubeExpansion_Cloud_AZURE_H5_V1.1.0 project (https://www.st.com/en/embedded-software/x-cube-azure-h5.html). I added N...
Hi, I am curious one thing when using the HAL libraries. Just as an basic exapmle i assign LED1 to PB12 pin of STM32F070CBT6 as an GPIO_output. And i want to use HAL_GPIO_WritePin(GPIOB, LED1, LED1_SET); instead of HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1...
Hi everyone,I'm new to embedded programming and trying to understand how SVC (Supervisor Call) works on ARM Cortex-M.I wrote a small program that triggers an SVC call, and in the SVC handler, I try to extract the SVC number by accessing the PC that w...
We are experiencing issues when using system bootloader on STM32H7 MCUs. Enter to the bootloader is correct - when BOOT0 pin is held high and reset is performed, MCU enters system bootloader. We use USB DFU for communication with bootloader and PC ca...
Hello all.Personal emotional outburst (just jump it if you don't work for stm):I can't understand how it's possibile, but every single time I trust STM and go for an update, everything stops working and I have to loose hours of my life trying to fix ...
Hi, My board consists of stm32h733 that interfaces SDRAM via FMC. I want to execute code from SDRAM. Code is loaded from external flash(OCTOSPI) to SDRAM at address 0xc0700000.But running the code from this region causes hard-fault disabling the Debu...
I'm using the internal temp sensor on a C011 chip *actually the STM32C0116 dev board) and trying to get an approximate reading in C, using __LL_ADC_CALC_TEMPERATURE_TYP_PARAMS macro.I understand that this won't be very accurate, but it seems that wh...
Hello :)I'm trying to get the mentioned display expansion board working with my NULCEO board. I already downloaded the X-DISPLAY examples and found a configured ioc file for an H723 so I replicated all the settings to match my H745 one.Unfortunately ...
