Posted on October 15, 2015 at 08:41 Hello, I 'm using a STM32F030C8 and I generate a tick of 1.136ms with the RTC with subseconds alarm. I calibrate the LSI with the HSI (=8Mhz) but I don't know how LSI and HSI frequencies change when temperat...
Posted on October 15, 2015 at 13:27Hi , I have an SPI program running successfully between two stm32f4 discovery boards using SPI_NSS as SPI_NSS_Soft. Some discussions on Stm32f4 SPI say that SPI_NSS_Soft has to be used when only one slave. Does th...
Posted on September 23, 2015 at 12:49Hello, there seems to be a serious problem with project re-generation with CubeMX. After regenerating a project, the linked files (for example HAL and configuration files, like main.c) point to the wrong directio...
