Posted on August 31, 2014 at 16:42 Hi folks, I debugged an issue with my own USB Full-Speed host stack where transmission stops at random. Chip: STM32F407@168MHz, USB_FS core, internal PHY In my test scenario I am using using...
Posted on March 25, 2015 at 11:06Is it possible to make USB HID Keyboard & Mouse with STM32L151? STM32F series have some demonstration source code for usb hid keyboard and mouse but STM32L151 has no demonstration source code. If STM32L151 make USB H...
Posted on March 25, 2015 at 09:15Greetings,I'm developing an application using STM32L053 micro. I use usb device (composite hid, msc). When I configure the system clock with HSI16, NO PLL all DIVS to 1 everything works fine. Now I need to change t...
Posted on March 25, 2015 at 02:45I've read just about all the existing posts regarding jumping from one code section to another and still I cannot jump without triggering a hard fault. I'm adhering to advice given such as always jump to an address w...
Posted on October 19, 2012 at 13:18I'm developing some software for multiple STM32 devices. One of the features it needs is a USB Virtual COM port.I've developed a version that works with USB VCP on the STM32F103 using this library:stm32_usb-fs-devi...
Posted on March 24, 2015 at 02:58 I'm looking intoSTM32F0x2_USB-FS-Device_Lib V1.0.0 particularly on STM32F072C8T6 with HID_CDC composite example. The first thing I observed, in usbd_cdc_vcp.c, void EVAL_COM_IRQHandler(void) { if (...
Posted on March 18, 2015 at 12:06Hi, I have a product which works as a USB composite device (CDC + MSD). This same product was previously designed to work only as a MSD device, without composite functionality. The device with composite funtionality...
Posted on January 16, 2015 at 06:58Hello, I am using an stm32f4-discovery board with MCU stm32F407. My intention is create a project using the STM32CubeMX c generator using both RTOS and USB Middlewares. I want to be able to see in my Device Manager...
Posted on March 03, 2015 at 11:24 Hello. I don't understand this code : /* Get tick */ tickstart = HAL_GetTick(); /* wait until command is send */ while(HAL_IS_BIT_SET(Device->SDSR, FMC_SDSR_BUSY)) { /* Check for the Timeout */ if(Ti...
Posted on March 13, 2015 at 18:41So I know ST doesn't expose viewing of the ULPI Register Array, but has anyone implemented code to access them ''blindly''? I need to tweak a few registers to try and pass USB 2.0 compliance but am having trouble fig...
