Unable to program STM32G031
Hello, I am not able to program STM32G031. I have Nucleo kit F401RE and STM32G031 connected to SWD. I have connected SWDIO, SWCLK, 3V3, GND and nRST.STM32CubeProgrammer can connect only in Hot Plug mode, but writting or errasing gives me: Error: Mass...
STM32H733 with HUB USB2514
Hi everyone,for my project I develop a board with MCU STM32H733VGT6. This project must to be have 4 USB peripheral ports.The MCU is configures as USB HOST, so i connected the USB pins (pin PA11 and PA12) as upstream.This nets goes to a usb HUB USB251...
STM32H723 SPI6 with BDMA doesn't work under Arduino Framework
Here's the definition of some functions that is used to allocate variable in D3 SRAM. typedef struct { uint16_t PackType; uint8_t Data[8]; uint8_t reserved[2]; }PinBasePack; #define sMemory(mem,type) ((type *)(sMem(&mem,sizeof(type)))) typede...
what is the cause of this hardfault ?
I execute my program on unmodified nucleo-u5a5zj-q , it reliably reach the "Default_Handler" from the default startup_STM32U5A5ZJTXQ.s.My understanding from the screenshot:It goes here because a hardfault occurs:SHCSR_S.HARDFAULTACT = 1HFSR_S.FORCED ...
Resolved! Is the stm system bootloader (trough CANBUS) just not woking when more than one device shares the bus?
Hi, i find myself wanting to use stm bootloader instead of having to code my own.:| My setup consists in 4 identical nodes hooked up to a 2m long canbus.I can boot and talk with the canbus bootloader only when a single node is powered on in the bus.(...
PWM generation error
I tried generating PWM on my stm32g070rb but when I connected my PA7 and GND to my oscilloscope, the output I got does not look like a pwm signal in any way, I have verified my connections and now I think the error is from my code.
STM32F105RBT6 INTERNAL RTC CLOCK SHIFT FROM LSE TO LSI
Hi ST Team, Currently i am using STM32F105RBT6 in our project. In this project i am using microcontroller internal RTC module to monitor the time with LSE clock for RTC run. When the LSE crystal(32.768) is not mounted in our PCB th...
STM32F411 Only running correctly in debug mode with debugger attached
We have a project running on the STM32F411 via the standard discovery board :https://www.st.com/en/evaluation-tools/32f411ediscovery.htmlIt has been verified that with the STLink port plugged in the BOOT0 pin is at GND and the NRST pin is at 3V. We ...
Resolved! STM32F3 USART1 in LIN mode, is it possible to use a DMA for outgoing messages, but RXNE interrupt/reading data register for incoming messages?
I acquired some code for an STM32F3 that performs LIN communication over USART1. Previously the code used DMA channels for both memory-to-peripheral and peripheral-to-memory transfers to/from USART1, but it had some problems that required restructur...
