Posted on April 02, 2018 at 23:30Hi everyone,I'm working on a board based on STM32F4XX. We plan to support USB Host on it for communication(CDC). I found there are 'USB On-The-Go Host' and 'USB Host' libraries. I'm not sure which one to use.First, I...
Posted on April 04, 2018 at 17:30HelloI have a STM32L4 MCU in my coming product. I'm running a master timer at 500Hz. The master timer triggers four other timers. All of these timers drive PWM at 500Hz at different phase. (Cannot be done using singl...
Posted on April 04, 2018 at 17:08Is it possible to use the I2S_CKIN external clock source for SPI rather than come off the peripheral clock? From the reference manual it appears that this external clock is available as a source only when the SPI is ...
Posted on December 29, 2016 at 11:21Hello,Currently, there is a possibility to generate C projects for different IDEs including SW4STM32, which uses gcc for compilation. But one can also use C++ code with g++ compiler supporting cool c++11/14 featur...
Posted on April 02, 2018 at 08:32I'm going to using AES feature in STM32F733ZE but the the datasheet doesn't have much information regarding AES .Do you know how much speed of AES in the STM32F733ZE ? And do we have any any demonstration evaluatio...

Posted on April 20, 2017 at 13:46Hi,Trying to calibrate the RTC, Using a LSE with 32768kHz xtal, which is running at a frequency of 32985.6Hz.// with 32768Hz LSE, with AsynchPre=0x7f(128), // CALIBOUT = 257.7Hz (measured on a scope)// 32768/128 = 25...
Posted on March 22, 2018 at 09:24hi to everyone I'm trying to use the library 21 sd_card demo by https://l.facebook.com/l.php?u=http%3A%2F%2Fstm32f4-discovery.net%2F&h=ATOUXBT8q6rvTUZYyodpiuulouhtO_tRdlKijHgKlwn4SBm-gCr7eZyZCTKuEFeoVBuX3WGl-hW51PLrn...
Posted on April 03, 2018 at 11:34Is there any possibility that STM32F7/H7 chip can drive an LCD-TFT 1600x480 display, or the XGA resolution is unbreakable limit for the controllers? Maybe someone tried something similar before and can share with his...
