Op-Amp on STM32G474RE

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...

Hello guys, so i have this project that require using interrupts that i'm not familiar with. could you help me?

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...

Arm Cortex

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...

Use timers to measure external clock frequency

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...

Is there a specific manipulation to do to communicate with UART bootloader using a second microcontroller as host ?

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...

Im trying to learn how to use the STM32 Discovery kits, the STM32F469NI DISCO, by the IAR 8.50.1 . I added a code from the internet that should make the leds blink, but i got some errors

Fatal Error[Pe035]: #error directive: "Please select first the target STM32F4xx device used in your application (in stm32f4xx.h file)" C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.4\arm\src\flashloader\ST\FlashSTM32F4xx\inc\stm32f4xx.h 80 ...

STM32H77 ADC1 random readings

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...

Does ST offer an SDK for Apple MFi? We are developing a device that talks over USB and need an SDK similar to that offered by NXP. https://www.nxp.com/..../.../mfi-made-for-iphone-ipad-ipod-accessory-software-development-kit-sdk Please advise
