I am writing a bare-metal USB CDC device stack on the STM32F411 discovery board which has a STM32F411VET6U controller. During enumeration I can see that the DAD field is not responding in the DCFG register. In other words when the stack tries to writ...
I'm debugging an issue where my application is using device mode USB with CDC-ACM and when I come to transmit a data packet on a bulk IN endpoint that is either 64 or 128 bytes in length, the data is not received by the host until either a different ...
In the OTG USB implementation, in USB_DevInit(), the PFIVL field of OTG_FS_DCFG is supposed to be written, eg. here, in the following way: USBx_DEVICE->DCFG |= DCFG_FRAME_INTERVAL_80;the DCFG_FRAME_INTERVAL_xx constants are defined in the respective ...
Hello I just found out that the HAL_Delay() delay actually takes 1ms longer than the desired value. Why?STM CUBE IDE 1.9.0STM32F072RBT6
Hi I'm using STM32F429ZI Nucleo board to work on integrating C270 Logitech camera through USB host. I'm not getting any interrupt in the USB IRQ handler when the device is connected. And it is said that LD8 LED will be ON when the USB is in device or...
Can anyone confirm whether my understanding of the following behaviour is correct (and whether there's any way round it):When the built in bootloader has been entered by jumping to it from firmware (i.e. the BOOT0 pin is NOT pulled high), and the boo...
Does ST have list of STM32 MCU's with 10/100 Ethernet MII/RMII module? Also does ST have an MCU's with 10/100 Ethernet MII/RMII module in 64 pin package.I know for STM32F207xx series 100 pin package.
In my STM32 software code three canbus messages sent (extended). When i connect the PCAN Can-USB tranciever i see my messages on the PC clearly. But after a while the state of bus gets "BUSHEAVY" and sending messages stop. Is the problem related with...
Hi,I found two implementation examples of USB HOST HID (for keyboard and for mouse) the examples can be merged, and they seem quite stable.https://os.mbed.com/users/hudakz/code/STM32F407VET6_USBHostKeyboard/https://os.mbed.com/users/hudakz/code/STM32...
