How to round division on STM32G0

I'm trying to implement an integer division with rounding. Obviously, by default integer division does floor and I was thinking I could use the remainder to determine if I should add 1 to my result.Processor cycles are at a premium in this solution (...

I need help selecting the microcontroller for the next project.

Based on operational requirements I narrowed down the selection to the STM32F413. The murky part is the field firmware update (customer side) capability. Is the STM32F413 capable of encrypted, customer side, firmware updates? I watched the Security r...

Where can I download the library "stm32f3xx_spi.h" and "stm32f3xx_gpio.h" ?

STM32L412: State of pin PB9 doesnt change, no matter the configuration

Hello,Thank you in advance for any answers and your time.I am using STM32L412CBT6P for my application. There are 2 custom boards with the same part and the following problem exists in both of the boards. Also attached is the connections diagram to th...

I want to develop a C program on the STM32F303 board that uses the SPI interface where the microcontroller is the master and the L3GD20 gyroscope is the slave: I want to perform a transmission to ask the gyroscope to provide me with the x, y, z coordinate

Considering that the gyroscope's chip select is the PE3 pin, how should I do this? The program below doesn't work#include <stm32f30x.h>void GPIO_Config();void SPI_Config();uint8_t L3GD20_Read(uint8_t reg);void L3GD20_Write(uint8_t reg, uint8_t data);...

STM32F767ZI : I2C2 hangs after few cycles of operation (With FreeRTOS)

I'm using I2C2 engine of the STM32F767ZI MCU on PF0 & PF1 pins as master to communicate with 4 slaves at 75khz. The operation is not using Interrupt on tx/rx or DMA and with FreeRTOS environmentSCL and SDA are pulled up on board with 4.99K.The pollin...

STM32U5 ADC1 bulb sampling multiple channels

Hello,I am using ADC1 on STM32U5 to sample two channels periodically using the DMA and a TIM6 trigger. I am doing this in bulb mode since I would like for the ADC capacitor to charge for the entire duration.I had thought that the ADC would sample th...

I can't debug the file I want, how can I make the file I select debug without there being another file?

Hello, I have had a problem and it is that I make a simple program, in this case the blinking of the led of the "NUCLEO-F401RE" board and I use the gpio that comes by default. The point is that when I try to debug main.c, another file is opened (whic...
