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...
Good day, I just brought a NUCLEO-STM32F404RE, I have trial several ways to upgrade the firmware but to no avail. Here are my board Info: ST-LINK SN : 0669FF373154333143092538ST-LINK FW : V2J33M25Board : NUCLEO-F401REHere are all the posts and advice...
Hello,I am hoping i can be pointed in the right direction.I would like to create, using an STM32H7, a device that has an ethernet port. The idea is simply to go to various sites and scrape info for processing later on. I guess this will require TCP/I...
HelloI am currently working on a microcontroller project I am building a GPS tachometer which transfers the NMEA data of the GNSS 4 Click Module from Mikroe via UART to my STM32L052K6T6 and outputs it to a displayI have so far UART initialized with t...
