Hello,after programming the code via the OnBoard ST-Link and connecting/disconencting USB on the Device side in order to find out if the works, I can no longer access the microcontroller.I have no idea what the rootcause is, 3.3V is fine. Could it be...
So the Blue Pill guy checks almost all the boxes for a new project I'm working on soon. 3 UARTS, M3, 72MHz, USB device, cheap, powerful *but* I'm not clear on the "fix" for being able to re-enumerate my device on USB. I must be able to change device ...
I want to use the bootloader feature (via UART) of the STM32L071RB. I have read the AN2606 and AN3155.If I'm right, the STM32L071RB has a V11.x bootloader and can be updated via UARTx, SPIx,and I2Cx.Is is possible to configure, which pins are used by...
Hi,My software sends a CDC bootload flag that asks the MCU to do a bootloader jump. The jumps works fine and I have no problem detecting the device change, in "control printers" on my PC (CDC to DFU). But on my collegue's PC his Windows does not see ...
I followed the custom hid example and finally got it to work, I can send 64 byte packets back and forth. The only issue now is that the device shows up as a mouse in the windows devices dialog.How can I change it to show up as a generic deviec?
i am using stm32l072XX I am using USB msc modefound below functions to detect connection and disconnection of usb in file usbd_core.cusbd_LL_suspend(***)usbd_LL_resume(***)they work properly when i insert or remove usb cable(i have added print statem...
I am using STM32f3 discovery kit with STM32 cube ide to interface the kit as USB HID mouse. I am trying to change the resolution of the mouse. The default resolution given in the Report descriptor is 400 dpi . (0x15, 0x81, // LOGICAL_MINIMUM (-...
So I'm back to getting the FATFS-SDMMC-FreeRTOS combo working on my board. I've got a simple project working without FreeRTOS and it uses the HAL_SD in polled mode. Stepping through my FreeRTOS project I see that this project calls HAL_SD_ReadBlocks_...
I can generate code from all the USB classes and it all works expect for one.custom hid class results in a "Driver Failed" message in windows.In device manager is says: This device cannot start. (Code 10)I have no clue what is causing this. I did not...
This proto board has a inventek system - ism43662-m3g wifi module. Using the at commands I was setting it to direct mode (at AD command). When entering this command then the communication from the wifi to the stm32 doesnot work. When in normal wifi,...
