Posted on September 04, 2016 at 10:02Hi,I meet a problem with my project in which a STM32F373 MCU is used to collect singnal in single-ended mode.I short the pin with GND to test the board,the ADC values I get seems to fluctuate like saw-tooth.The g...
Posted on September 06, 2016 at 20:40There are examples counting clock pulses with the DWT_CYCCNT, but it will overflow in time. Counting pulses is easy if there is no overflow, but with overflow I am sure there nice way of doing it. I could do some...
Posted on September 06, 2016 at 21:37Is it possible to read the device type in user code? I would like to write some code that uses the crypto acceleration hardware if it is running on an STM32F415 and falls back to software implementations if it i...
Posted on September 06, 2016 at 18:47 This is more of a C problem than Arm problem, here too are some people who know their C. I am reading the value of DWT_CYCCNT; When print it via Uart, after a while it becomes negative. The most ...
Posted on September 04, 2016 at 10:31I'm trying output a sine wave on STM32F429I, the HCLK is 168MHz. I want my sine wave start just as I detect a rising edge on one GPIO. So, I use software trigger, call HAL_DAC_Start() in the ISR of a rising edge ...

Posted on September 05, 2016 at 17:54I am messing around with the SMT32F429 discovery EVK. I am trying to play with booting into the internal bootloader and may have blown it away. Using IAR workbench I look at the device's memory location 0x1fff000...
