Posted on August 06, 2014 at 10:12 Hi, I'd like to implement a composite USB device with MSC + a custom class. I'm using a STM32428I-EVAL board and some code generated by STMCube. MSC alone is working (with bulk endpoint 0x8...
Posted on August 05, 2014 at 12:50I imported an example with RTOS (FatFs_uSD_RTOS) and I found some bug. In function HAL_Init() is called HAL_SYSTICK_Config() but SysTick_Handler() call xPortSysTickHandler() before osKernelStart() so we have an ...
Posted on July 30, 2014 at 15:16Hi, I'm trying to initialize a usart, and read some data on a Terminal. The terminal receives some data but not the good one. The problem seems to be a clock problem, and the usart register BRR looks wrong. Moreover, ...
