USART Not Receiving Data (Polling)

Posted on May 31, 2017 at 17:06Hi guys,So I'm using an STM32F1 and am trying to send data from a serial terminal (RealTerm) to USART3 via a FTDI USB-UART converter cable. I have written code to poll for data on the RX line but for some reason my USA...

Phase-shift PWM with STM32F407

Posted on February 27, 2017 at 15:10How can I create a phase-shifted pwm signal ? The frequency is fixed. The board is STM32F407 discovery board so I am not 100% sure if this is possible.If it is, how can I achieve this?#phase-shift #stm32f4-discove...

Emulation PCM Highway by SAI interface

Posted on June 01, 2017 at 03:47Hi, all,I have to interface PCM highway for SLIC thru MCU.Most VoIP chipset has PCM highway interface to be connected with SLIC directly.But, I want to use general MCU, not VoIP chipset.I am glancing the SAI interface...
