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 have STM32L431CB , I have interfaced SRAM with SPI to it. I am looking for effective solution for data compression ( like LZ77 ) for the same.Are there any integer data compression libraries ( like LempZiv , Huffman, etc ) available for STM32L4...
I have been trying to program the Op-Amps on STM32G474RE using the latest STM32CUBEG4 version 1.2 and my version of STM32CUBEMX is version 5.6.1. I am trying to get PGA mode to work. In STM32CUBEMX, I selected PGA connected. When I tried to bias one...
i'm trying to send data using SPI. i'm getting started with a simple example with is a loopback test. so when i used the HAL_transmitReceive(..) it worked pretty well but when i tried to use it in interrupt mode the last byte of the array that i'm se...
Hello everyone !I wanted to ask you please what type of document I can see for information on Cortex M3 / M4 / M7 processors, I would like to see the generic versus specific instruction sets, optimized execution, etc.Do you have an idea ?Thank you ve...
I am trying to implement I2C communication with L432KC (bare metal coding) to interface peripherals like port expander, eeprom. But I am having a hard time figuring out the TIMING register. I have several questions:tPRESC = (PRESC+1) x tI2CCLKThis is...
I have two external clocks connected to TIM1 and TIM2 of the stm32f746 (disco). I'm basically trying to implement a frequency counter of the clock connected to TIM2. The TIM1 clock will act as window (driven by a TCXO). In my test setup the TIM2 cloc...
Hi,I have a NUCLEO-F429ZI board and am trying to get ADC1 to convert one channel (channel 3) when triggered by TIM2 (every second).As I don't have an oscilloscope I wanted to measure the conversion time - to make sure everything is configured correct...
Hello,I am trying to communicate with the UART bootloader (NUCLEO64 F446E) using a second board (NUCLEO32 L432KC).I am using USART1 (PA_9, PA_10), on which I am trying to send the 0x7F frame to activate UART bootloader (after having activated bootloa...

We generated ADC code for STM32H755 using CubeMx. ADC1 is setup a single channel, one shot conversion. We are using internal Vref at 2.5V. We are reading 0.9V as a test and the DR keeps changing randomly. What are we doing wrong? Thanks!// adc.c gene...
