Hello.I am considering a project to exchange a small amount of text data using only an STM32G0 microcontroller and a USB memory stick.As a candidate, I found the following microcontroller which supports USB2.0 FS device and host controller.STM32G0B0V...
I have stm32f407vgt6 from devebox. At first, I wanted to do led blink and it worked fine when I supplied it with external power via 5V pins. Then, when I tried to use UART pin (PA_9, PA_10) to print something to USB to TTL module, it did nothing. UAR...
Greetings,I'm struggling to get GPIO configuration to work without hitting the HardFault_Handler. If I configure a single GPIO, like this:__HAL_RCC_GPIOB_CLK_ENABLE();GPIO_InitStruct.Pin = GPIO_PIN_7;GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;GPIO_I...
Hi, I am having trouble getting the Timer to trigger a DMA -> SPI operation. Namely, I want to set the timer up to run,. Then, get every overflow event to trigger the DMA to move a byte into the SPI. The SPI should auto-send. Then, the cycle rep...
Hi all,I use STM32CubeIDE version 1.12.0 and STM32CubeMX Version: 6.8.0-RC4.The MCU used is STM32U585When i start my software in debug mode, some times a HardFault is detected on SysTick_Handler function.If i use the IWDG (with compilation option nam...
I've been writing apps using the STM HAL drivers for a while. I'd like to move to the low level drivers in order to have a better understanding of what's happening in my app. Comms over a UART with DMA is a critical part of most of my apps so I'm s...
Dumb question, can the DMA perform separate, parallel operations with the different channels? For example, could I use the DMA to transmit with the UART and the SPI devices at the same time without one interrupting the other? I'm unclear from readin...
I would use a b-l072z-lrwan1 to implement a lora gateway using ping pong example and send data to PC through serial, receiving data from serial and send response to other nodes that are still b-l072z-lrwan1
Posted on May 18, 2018 at 07:29 Hello everyone, I want to run 2 rotarty encoders on my STM32F I'm using cubemx. The first one is a 2000 step rotarty encoder like these: https://www.aliexpress.com/item/1pcs-E6B2-CWZ1X-2000P-R-encoder-for-Omron...
Hi All,I have two Questions,The first one is:I was trying to use one of the SPI examples provided by ST SDK, but the "STM32L476G-EVAL" target doesn't have an SPI example, so I used the NUCLEO-L476RG SPI_FullDuplex_ComDMA example as a reference.I was ...
