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...
Hello all-Working with the SPI peripheral on the STM32F411VET6, we need to connect to a device that sadly requires the CS line to toggle with every byte sent. Just about every example code runs along the logic of "write to the SPI data register and ...
Hello,I need to drive some power mosfets (STP55NF06) from open drain outputs.The gate and mcu output will be connected to a pull up resistor to 12VAre the TT and FT pin voltage limits applicable when used in open drain mode?If yes, I will amplify the...
Hi all,I was reading through the documentation of the STM32H723 to find out what clock speed I can configure the FMC to run at using an external SDRAM. Looking at older posts and videos there is mentioned 100 MHz, but when I look at the newer/revised...
I’m using CubeIDE + STM32G4 to configure DMA transfers and I’m a bit confused by the interrupt code it generates. Configuring DMA transfers on TIM8 defaults 'DMA1 Channel1 global interrupt' to enabled and generates a DMA1_Channel1_IRQ_Handler functi...
Hi, i want to connect two joysticks and some push buttons to my STM32F103C8T6 and make something like a Playstation controller, using USB HID to make my PC recognise it as a JOYSTICK Gamepad and then i can like play fifa with it or something.I saw a ...
Hello everyone, I am designing a PCB and I need a ST-Link connection for debug and programming. This is my first time in this kinda stuff so I need some help.Which one should I have to use for debug and programming?As I understand Serial Wire is for...
Hi,I need a DMA setup for 4 separate UARTs in an STM32G473 controller. The idea is to always be able to receive data through rxDMA, and only invoke txDMA when sending data. The data that I receive changes in size, is between 20 and 300 bytes, starts ...
Hello! My project is almost finished, but I had a little problem. On the dashboard, I can optionally read the speed and coolanz water temperature from the can bus or with sensors (vr sensor, ntc). In the case of the can bus, the display works proper...
Hello. I have few questions on UART half-duplex single-wire peripheral. I'm using stm32f303k8.In RM it states that TX and RX are internaly connected and TX is low (or whatever "released" can mean) when it's not transmitting. This means that when no t...
I am programming my custom board with STM32G491CEU6 and STM32CubeMX 6.5.0.The code is generated with STM32Cube_FW_G4 v1.5.1 firmware.Steps to reproduce:Select 'access to MCU selector' after opening STM32CubeMX.Select STM32G491CEU6 and create the proj...
