Posted on May 30, 2014 at 11:24Hello, I'm planning to use a STM32F072 for a USB device. When I browsed its datasheet, I found that PA13 can output USB_NOE as alternate funtion. There is no functional explanation of this pin in the reference manual, ...
Posted on May 30, 2014 at 03:43The STM32CubeF4 __HAL_UART_CLEAR_FLAG( ) macro is incorrect because it does a read-modify-write. If a status bit becomes set in the USART_SR register by the hardware between the read and the write, that change will be ...
Posted on May 26, 2014 at 23:29In the STM32CubeF4 FreeRTOS Application examples, any HAL functions that internally use the HAL_GetTick() function for timeout operations will not work correctly because the SysTick ISR has been assigned to the FreeRTO...
Posted on February 05, 2014 at 11:37Hi all,I a using an STM32F407 device with ST standard library and USB lib.In Handle_USBAsynchXfer() function in usbd_cdc_core.c file:There is a potential bug when roll-back occurs.Two pointers are used:APP_Rx_ptr_...
Posted on May 22, 2014 at 20:21 After much digging, I discovered that while the reference manual for STM32F4xx says you can have 3 IN endpoints, it fails to prominently specify that these can only be the endpoints numbered 1, 2 or 3. The H...
Posted on May 25, 2014 at 05:11On the NUCLEO-F401RE, using the SystemClock_Config() funtion from the STM32F4xx-Nucleo template from the following file: STM32Cube_FW_F4_V1.1.0\Projects\STM32F4xx-Nucleo\Templates\Src\main.c I cannot get the HSI cali...
Posted on May 24, 2014 at 21:27Hi All, Using the USB-FS HID device example , STM32_USB-Host-Device_Lib_V2.1.0. Using the FS/Internal PHY with DM DP and VBUS connected to USB Cable. Using a basic custom board with just a STM32F205, power, JTAG, seria...
Posted on February 28, 2014 at 13:10Hi,I'm trying to port a Java SIP stack (http://www.mjsip.org/mjsipME.html) to the stm3240g board. MJSIP already did a port of their sip stack to cldc1.1 so I thought I could go straight ahead.It seems that the cld...
Posted on May 21, 2014 at 03:28In version 1.1.0 of STM32CubeF4, the BSP for the Nucleo boards has an LED control bug - the functions operate in reverse. That is, BSP_LED_On() turns off the Nucleo LED and BSP_LED_Off() turns on the LED. These functio...
Posted on May 21, 2014 at 15:54I am trying to make DFU work on STM32F205ZF. At the moment it is recognized by the host PC. I can upload flash to PC, verify it, but ''DfuSe Demo'' stucks when it comes to updating a flash. It manages to erase just sec...
