Resolved! NUCLEO F446RE
About the board NUCLEO F446REIs it possie, with that board, and for learning purpose, to drive external devices such servomotors?If so, how are they connected to the board?Thanks

Resolved! STM32U5 - QSPI display
I'm planning a new device and wish to use an STM32U5 series processor.We would like to reuse an existing display. However, this has a QSPI interface (at 50MHz).Is it possible to use one of the Octal-SPI interfaces on the STM32U5 series for driving a...
STM32F407G discovery
i have an SPH18R1LM4H-1 audio sensor developed by Knowles company, you can also check this on their site and datasheet. it needs an clock frequency of 2.4Mhz. Means when we input the clock frequency , the audio sensor then generate an data according...
Resolved! How to Convert From ISP to CAN
HiI got this problem where I got an MCP2515 that wants an ISP type signal, and then converts it to CAN. I am only familier with the CAN protocol and the HAL library, so is there an easy way to make the STM32 convert the code from CAN to ISP?
Resolved! H-Series support for external program flash
The STM32 families typically use Quad-SPI for executable external flash, from my research (ref)But the only H-Series options with Quad-SPI are expensive! Are there any alternative methods to executable external program space?
STM32L010K8 on/off ADC Vrefint in low power run mode?
We have product that runs on two AAA batteries based on STM32L010K8 and according documentation this product should consume around 26uA when in low power run mode(32Khz clock source).Measurement showed that micro consumes around 90uA which is unaccep...
Driving ST7735 with a F4xx discovery board.
hello everyone, I have been trying to display even basic text on my TFT 1.8" Display and am yet to get anything but gibberish. I am using this library to interface with it. https://github.com/afiskon/stm32-st7735 I have followed plenty of tutorials...
what is HAL_OSPI_AutoPolling() ? how to fix it ?
After trying the sample code from STM32Cube_FW_L4_V1.18.0 for octo spi I getting stuck on HAL_OSPI_AutoPolling(hospi, &sConfig, HAL_OSPI_TIMEOUT_DEFAULT_VALUE); it is not working, after reading posts and STM32L4Rxxx and STM32L4Sxxx device errata I fo...
Waking up from STOP mode using UART
Posted on May 09, 2018 at 22:36I am using STM32L051 mcu. The mcu goes to STOP mode after initialization and only wakes up if there is any incoming byte at USART1. MCU wakes up with START_BIT_DETECTION on USART1 and goes back to sleep after it receiv...
Resolved! Broken device through optoin bytes
Hello, I am currently fiddling around with a STM32G491 in bare metal. I wanted to test the write protection. So I executed following code FLASH->KEYR = FLASH_KEY1; FLASH->KEYR = FLASH_KEY2; while(FLASH->CR&bit31); // wait for unlock...
