Posted on February 04, 2015 at 12:58I am using ULINK-PRO to debug a STM32F4. I have connected the target as per the Cortex Debug+ETM 20 pin. I have connected TRACE_D1 to nTRST as I believe these pins are multiplexed within the ULINK PRO. i.e. nTR...
Posted on February 04, 2015 at 07:47 Hello, we have a small software (bootloader) running on a STM32F103. In a new project, we selecte a ''smaller'' type the STM32F105 with less pins. In the bootloader we set a push pull port high. On the new contro...
Posted on February 04, 2015 at 14:06 hi i have an stm32f4 and i try to write and read flash value. #include < stm32f4xx_hal.h > #include < stm32f4xx.h > #include < stm32f4-hal /stm32f4xx_hal_flash.h> float dataflash1 = ...

Posted on February 04, 2015 at 01:24 Hi there. I can't get my head around this and was hoping someone could help ... despite having set a higher priority to the SysTick irq, it doesn't seem to decrement an integer variable when called fro...
Posted on February 03, 2015 at 02:20Hello, I am endeavoring (as with every hair-pulling experience with the STM32F4) to measure/capture LOW frequency pulses. For this, I'm assuming I need to use a 32 bit timer: TIM2 or TIM5. This is a bit of a dilem...
Posted on February 02, 2015 at 00:12 I'm testing ST's USB Virtual COM Port example code(fromSTM32_USB-FS-Device_Lib_V4.0.0) on STM32F103ZET6 board，and the binary that is produced could not enumetate when compiling with gcc(-O0 or -O2 or -O3)....
Posted on September 03, 2014 at 18:42Hello everyone, I was wondering how to turn of the UART Interrupt, I am using HAL_UART_Receive_IT to receive incoming characters on the serial port. periodically I want to take over the port and control it manua...
Posted on January 30, 2015 at 13:09 Hey Everyone, I'm using an STM32F405 on a custom board with the STM32CubeF4 library. Whenever I enable the TIM4 peripheral, the TIM4->DMAR register automatically changes from 0 to 1. This is causing th...
Posted on January 30, 2015 at 09:52 I would like to repeatedly enable/disable TIM1 CH1 and CH1x outputs. Here is my code. static u8 step = 1; switch(step) { case 1: TIM_SelectOCxM(TIM1, TIM_Channel_1, TIM_OCMode_PWM1); TIM_CCxCmd(TIM1...
