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...
