Posted on April 08, 2015 at 13:07Hi all,I�m designing a STM32F107VCT based embedded system. Unfortunately I�ve several problems with this part. For example the part wasn�t program correctly (Verification failed), and when I removed and soldered anot...
Posted on April 03, 2015 at 20:02How to find out APB1 clock frequency? I want to know TIM2 clock, which is connected to APB1. I use STM32F103 and standard peripheral library.Thank you.
Posted on April 18, 2015 at 06:47Hello,I have read the datasheet of stm32f407 about the DAC output range. When buffer on, the min DAC_OUT is 0.2V and max DAC_OUT is VDDA-0.2V.However, I get 0.069V at 0x000 and 3.272V at 0xfff rather than 0.2V and 3....
Posted on April 18, 2015 at 10:08Hello,I'm running an Cube project with FreeRTOS, with iWDT enabled, on STM32L1 and debugging on IAR.iWDT is being cleared in its own thread, with the same priority as the other threads.No thread is a blocking thread....
