I've written a simple program which should write data through UART to a PuTTY terminal on my laptop. I have the L4R5ZI Nucleo board, connected to my laptop via USB. I'm only sending 'Hello World \r\n' however, I get 'H9Go]oG #' back every time. All o...
I tested the GPIO performance on both cores CM7 and CM4. To do this I used the following loop: /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ LL_GPIO_SetOutputPin(DBG_D...
I decided to run an experiment on my STM32F767ZI microcontroller. I turned on the cycle count register (DWT->CYCCNT) and decided to run the program step by step on Keil. I set the clock to the maximum amount possible with a PLL on this MCU, which is ...
I have designed a target board based on STM32G484VE and I am encountering a problem with GPIO outputs while powering on.The requirement is no output should get high status while powering on or during reset. So I have configured the IOs using CUBEMX ...
Hello,I'm currently using and working on B-U585I-IOT02A Discovery kit. Today, I supply the board with STLINK source via CN8 connector. But I want to be able to supply it with 12V voltage. So I will now supply the board via VIN pins and connect jumper...
I want to make robotic arm , CNC controller for this purpose which STM32 is capable to do DSP, arithmetic and floating point calculation Faster (less clock cycle for execution)without much execution code delay?So interpolation and trigonometric fu...
We make below code.The variable a is written from both main function and interrupt function.When accessing variable a with the main function to realize exclusive control, interrupt disable and enable (__disable_irq(), __enable_irq()) are used.How ...
I am working on this project and I want to have full control of the sent / received messages from my STM32F746G. Even when starting an empty project without ETH these messages are sent from the STM
