I'm in the process of building a USB composite CDC + MSC device on the STM32F4 Discovery board but am having trouble getting windows to recognise it. Using USBlyzer all the descriptor info seems ok but windows will only recognise the CDC (virtual com port). The port gets enumerated and ...

Beside the point from Soup ( the failing malloc caused by a heap that is only 0x200 by default) some Windows version have a problem with the line coding in the example. In the usbd_cdc_if.c you should add: /* USER CODE BEGIN PRIVATE_VARIABLES */ USBD_CDC_LineCodingTypeDef LineCodin...

I am basically trying to implement a USB device (CDC-ACM to be precise) that utilizes suspend/wakeup. I am usingthe ''STM32_USB-Host-Device_Lib_V2.1.0'' and looked into the HID example for help. Unfortunately there is no example that shows the USB HS with suspend/wakeup using an ...

Flash与 NANDFlash。 NORFlash数据总线和地址总线是分开的,所以可以按字节访问。但是NANDFlash数据总线和地址总线是共用的,所以只能按“块”来访问内存。 所以在功能上可以认为 NOR是一种断电后数据不丢失的RAM,但它的擦除单位与 RAM 有区别,且读写速度比 RAM 要慢得多 。
Since I started from the USB-CDC code example from ChibiOS which is GPLv3, I think I am forced to release this code under GPLv3 though I don't care what you do with the code. I asked Giovanni and he said "there is not much meat" in it anyways. Star 0 Fork 0 捐赠 0 人次...
