Posted on December 22, 2015 at 13:25 trying to use binary semaphore on STM32F4 discovery board with FreeRTOS gives some strange (even wrong) results. First and foremost, documentation for FreeRTOS says: SemaphoreHandle_t xSemaphoreCreateBin...
Posted on December 22, 2015 at 10:47Hello!I have already coded for CAN Loopback mode and it works. However, when I changed the mode to CAN Normal Mode, I am unable to hit Receive Handler, but I can hit transmit Handler.int main(void) { /* USER CODE...
Posted on January 27, 2015 at 21:17I have built a system using STM32CubeMX 4.5 and STM32Cube v1.1.0 for a F072 CPU. I just started implementing the UART parts. I want to run using DMA, but I can't get it to work. A call like HAL_UART_Transmit_DMA( &...
Posted on December 16, 2015 at 08:55Hi, I just noticed something strange using the RTC of STM32F407 with CUBE HAL Library. When calling HAL_RTC_SetTime(); I see no register writes are performed for the SecondFraction field of the RTC_TimeTypeDef str...

Posted on December 19, 2015 at 19:15 Hello, I tried to get working the uart with interrupt. I can send and receive data by polling with the function HAL_UART_Receive. First how I can do to check if a byte is in the data_register, because whe...
Posted on December 22, 2015 at 15:01Hello to all, I can set the ADC1 Vbat Channel für a STM32F2xx with HAL_ADC_ConfigChannel(). But how can I reset the bit in order to save the battery from leakage current? I could not find a cube function similar...
Posted on November 01, 2015 at 07:54Hi!Actually I'm new in STM32.I have a problem in creating pwm. while making pwm in 20KHz with timer1, the frequency suddenly changes during the run! it is programmed to be 20KHz but it jumps to 2 or 3KHz.i want to...
Posted on October 08, 2012 at 09:10Dear Friends,I read document AN4065 of ST. it told that use must configure 2 conditions for application code, I understand condition setting linker 0x08003000 for KEIL compiler.Does anyone help me explain condition...
Posted on September 07, 2015 at 11:34Hello, I have some problems with FMC when I try to port my code from SMT32F407(with FSMC interface) to new project based on STM32F746(with FMC). The only changes I've made are timings(adapted to 216 MHz clock) an...
