Posted on January 19, 2016 at 20:22Hello. I'm testing STM32F7 discovery. The library is STemWin 5.28. I try to test WeatherForecast (the example form the Segger web site). The compiller gives a lot of errors concerning animation. Is it not included ...
Posted on January 21, 2016 at 01:03I have a problem with RTC_ALR behaviour. The RM0008 in 18.3.2 says:All system registers are asynchronously reset by a System Reset or Power Reset, except for RTC_PRL, RTC_ALR, RTC_CNT, and RTC_DIV. The RTC_PRL, RT...
Posted on January 20, 2016 at 01:53 Hello! I have configured my filter banks. However, the standard ID that the receive FIFO0 register is reading after controller transmits a response to my module is not what I expect. Hence, I suspect t...
