STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi,I am using STM32L07xxxI want to use USART4 and USART 5 So i generated code using STM32CUBEMXBelow is generated code for interruptvoid USART4_5_IRQHandler(void) { /* USER CODE BEGIN USART4_5_IRQn 0 */ /* USER CODE END USART4_5_IRQn 0 */ HAL...
Hi, everyone I have a weird problem, my stm32f103c8 chip goes to reset mode(nRST pin voltage goes below 1.5 v) after working for couple hours. The MCU is switching the GPIOB1(frequency is 500KHz). Do you have any suggestion about this issue? Is it a ...
I am trying to interface IC ADS1115(ADC) with STM32F401RE through I2C communication.I am not getting ACK from Slave after writing data to Config register.But getting ACK for device address(0x92) and also in I2C1->SR1 register AF-Acknowlege failure b...
So I'm trying to control 8 different PWM signals simultaneously using DMA (Nucleo-F429ZI connected with 8 lines of SK6812 LEDs).So save memory space I implemented the strategy described in this blog to save memory. Basically using half-transfer and f...
Hello, I would like to replace STM32L072CBT with STM32L4Q5 in my development. I found that there is: STM32L4Q5CGT6P and STM32L4Q5CGT6. Unfortunately I can't find a data sheet for STM32L4Q5CGT6P. In the CubeMX I see that PIN46 and PIN22 with VDD12 ar...

I have use STM32F0 microcontroller.I try to integrate the stm32 with OLED(SSD1306:128*64).It's an I2C communication. The issue is while clearing the display takes some seconds(like 2sec.).How can I make it faster?I have attached the issue portion ima...
Hello,I would like to send float numbers to UART and then check it in terminal using UART <-> USB converter. Could you provide any function which transmits float to UART? I am using STM32CubeIDE environment.Thank you.
I couldn't find documentation about FOC for high performance controller STM32H7, is there anything available? does anyone know useful resources for the implementation on this controller?Thanks in advance
Hi, I need your help, please:I'm using a STM32 and the STM32CubeIDE and I want to communicate the MCU and a FPS module R502 through LPUART (Low Power UART). When I send the correct packages, the FPS answers correctly (I check that reading via serie w...
