![]() In this tutorial we are using PIR sensor to detect motion and turn ON bulb using Raspberry Pi and Hexabitz. Motion Detection Automatic Light On/off With Hexabitz. The STM32H5 Nucleo-144 board comes with the STM32 comprehensive free software libraries and examples available with the STM32CubeH5 MCU Package. This project is about reading real-time temperature, humidity sensor data from STM32 Nucleo-144 using Bluetooth. Is there something under the mbed hood that is stepping on my register accesses? I see this behavior for both GPIOB and GPIOC, but GPIOD behaves as expected. The STM32H5 Nucleo-144 board does not require any separate probe as it integrates the STLINK-V3EC debugger/ programmer. ![]() If I use the already configured GPIOB->MODER for the register references, the extra processor time spend doing the redirection actually allows the register to revert before the first read completes, so I never see the written value stick. When I hard code the register address, the write takes effect, but after a short time, the register reverts back to it's reset value. It appears that the HAL headers are not he problem. It doesn't appear that any ports have their configuration locked. I get the same behavior on both an F746 Nucleo and an F446 Nucleo board that I tested. For now, I'm just going to make my own HAL header file for the GPIO registers, but this seems like it should be addressed(pun intended). In this tutorial, we explain step-by-step how to blink a LED on the NUCLEO-L476RG board, using the STM32CubeMX tool, HAL, and STM32CubeIDE. This leads me to believe something is amiss in the HAL stack.

If I remove HAL abstractions and "poke" the register directly in this way: In fact all of the other PORTB-> registers (OTYPER, OSPEEDR, PUPDR) all return 0x00000280, which is not correct. For example, setting PORTB->MODER has no effect and the value remains at 0x00000280(the reset value). I'm moving from the platform agnostic DigitalIN, DigitalOut, PortIn, PortOut to STMicro port specific references such as PORTB->MODER.įor some ports, my GPIO initialization and use of GPIOs works(Port D seems to work correctly), but PORTB and PORTC are not working with the HAL abstractions. I'm trying to remove MBED generalized HAL abstractions from my STMicro Nucleo-144 board based project and am getting strange behavior. Nucleo 144 boards and GPIO HAL - Not all ports work To start a new conversationĥ years, 8 months ago. Now select the COM port to which your Nucleo board is connected.Important changes to forums and questionsĪll forums and questions are now archived. This is mentioned as LD2 on the Nucleo board and it is connected with the PA5 pin of F103RB. The above code blinks an onboard LED of Nucleo-F103RB after every one second. ![]() the loop function runs over and over again foreverĭigitalWrite(LED_BUILTIN, HIGH) // turn the LED on (HIGH is the voltage level)ĭigitalWrite(LED_BUILTIN, LOW) // turn the LED off by making the voltage LOW initialize digital pin LED_BUILTIN as an output. the setup function runs once when you press reset or power the board This example code is in the public domain. Model, check the Technical Specs of your board at: If you want to know what pin the on-board LED is connected to on your Arduino The correct LED pin independent of which board is used. It is attached to digital pin 13, on MKR1000 on pin 6. Most Arduinos have an on-board LED you can control. STM32H743 Nucleo-144 STM32H7 ARM Cortex-M7 MCU 32-Bit Embedded Evaluation Board. Turns an LED on for one second, then off for one second, repeatedly.
