I just made a FS_USB_MSC project and I wanted to access the flash from my windows computer.when I use RAM space for the STORAGE_Read_FS and STORAGE_Write_FS I can Access the RAM without any problem. and also I can format the space in windows to be ab...
Hi,I had worked with stm32f407 using HAL libraries earlier but it is different UART peripheral from F4 a bit. I use again HAL_UART_Receive_IT() and HAL_UART_RxCpltCallback() for stm32L011 in the user file. I implemented the Callback function respec...
I am curious if the STM32G0x1 can manage a DRP and a UFP USB-C as a charge through application?The USBPDM1 doc mentions other IC's and possibly other breakout boards.Is there a timline on when the TCPP03-M20 and documentation will be available?Cheers...
Howdy everyone.I need my MCU to be selfaware of what FW version is currently flashed,so far im just manually typing the git commit hash inside a const string every time i change the FW version.It looks to me like a feature that should be supported so...
Hi. I'm having trouble managing a USB slave on STM32L4 using interrupt. I'm able to make it work using polling, and on a previous F3 project, had polling working.From RM, NVIC section, F3 has 3 USB lines: Wakeup, LP, and HP (HP and LP are shared with...
Just discovered that ARP request messages are padded with 18 bytes of trailing zero bytes, making them 60 bytes long instead of 42 bytes. A third party device doesn't like this and fails to respond to the ARP request message. I'm using a STM32F476 ...
Hello , I have STM32H750x MCU. I would like to know why the ETH DMAMR->SWR (software reset bit) is still ALWAYS SET?I know even the HAL driver is trying to do the SW reset on the ETH DMA and MAC. I know I should have an enabled and stable clock for t...
In the example while(HAL_I2C_Master_Transmit_DMA(&I2cHandle, (uint16_t)I2C_ADDRESS, (uint8_t*)aTxBuffer, TXBUFFERSIZE)!= HAL_OK) { /* Error_Handler() function is called when Timeout error occurs. When Acknowledge failure occurs (Slave d...
hello everyone, I am trying to generate a square wave at a desired frequency. I am supposed to use the TIM3 peripheral. I selected the "Output compare CH1" for channel 1 section and under this section it asks me for a pulse value (which I know is th...
If the H7 HAL_SPI driver function HAL_SPI_TransmitReceive(......) is called in my main(),It runs correctly, I can transmit and receive data correctly. But it is called in my EXTI9_5_IRQHandler() interrupt , It runs dead loop, and can't return.
