Hi, I've recently retired from being an electronics design engineer for over 40 years. I wanted to have some fun playing around with micros to do some basic control. I have both the Nucleo-F030R8 and STM32F4 Discovery evaluation boards and have bee...
Hi,I have a board, with STM32f303. It generally works fine, but I am using the opamps and they are causing me trouble. I have set them up to have PGA of 16, and be internally connected to the ADC, and have test points on my board where I can measure ...
Dear experts,i try to use the float library with printf or vsnprintf. The option nano has been checked, the -u _printf_float too. The latest version of STM32cubeIDE, the proc is STM32F446RE. The value of floats are correctly displayed in debug but i...
I want to learn that Can we use 4x I2C communication protocol in STM32F407?
Hello,STM32F74xxx Reference manual (RM0385) 6.3.2 I / O pin alternate function multiplexer and mapping has the following description.After reset the multiplexer selection is alternate function 0 (AF0).I think that when AF0 is selected, it will be ass...
Hello everyone,I am currently working with the STM32G474QET6.Trying to measure Honeywell pressure sensors whose output voltage ranges from 0V to 3V.The problem is that the measurements have a much greater error than indicated in the data sheet.To rul...
Hi,I have a circuit board that uses STM32F401CEU6, and now I decided to replace it with STM32L433CCT6.I want to know the transplantation method from using STM32F401CEU6 to using STM32L433CCT6 in the program.Regards,Zhao
Hello! I can't experiment - I can't receive parcels with a CAN harness and special software. Here is a similar experiment https://www.programmersought.com/article/2185872275/.I have elements:1 stm32f103c8t6 board,2 Debugger st-link v2 (china),3 SN65H...
Hi all,I'm tying to use the ITM printf on my STM32H723 Nucleo board in my Keil project without success. I configured the HAL with CubeMX and add the initialization for the SWD_Init(). I enabled tracing in Keil but I do not get any output. I checked:S...
Hello i am using Nucleo F746ZG board. When i run simple LED blink code with below code its not showing LD5 (Over current) on.#include "mbed.h" // Blinking rate in milliseconds #define BLINKING_RATE 500ms int main() { // Initialise the digital pin...
