Posted on November 15, 2017 at 11:38 HiWe are using Tianma’s - TM070RVHG01 (800X480 resolution) TFT in our design with STM32F429 processor working at 168 MHz frequency. We are using EmWin Library on RTX operating system with LTDC support. We are...
Posted on November 13, 2017 at 22:33I'm trying to do some calculations to held resolve some ADC issues and I am unable to locate the value Radc(max) for the L496. I am able to locate it for the F1 and F4 series but I can't find anything in any of t...
Posted on November 04, 2017 at 08:19Hi: Can STM32F401's PCM be set as the following formats ? PCM Slave , FS=8Khz ,BITS=16, Mono ( which means BCLK= 8khz * 16 = 128Khz) After some tests , i find the PCM can only be used as stereo mode (BCLK...
