Posted on January 15, 2017 at 09:01Hello,I have been using the RTC of the Nucleo 144 F767 board with the onboard 32768kHz oscillator and I noticed that there is a large drift (~2 minute lag per day or ~1570ppm).Based on the datasheet, the crystal dr...

Posted on March 03, 2016 at 10:14Hello, I have been designing a controller for an interleaved power converter using the STM32F746 Discovery board. Since I need to have four pulses with different duty cycles and phase delays (which will be variable),...

Posted on January 17, 2017 at 20:42Thanks for your response. The digital calibration does not apply for this case, since, as I wrote above it can manage a maximum drift of Â±448ppm and I am observing a drift of 1570ppm. That's why I am obligated to ...

Posted on March 26, 2016 at 06:48Hello,in order to keep the USART_puts function as is (send 8bit characters), I propose you to create an intermediate function which will split the buffer of 32bit elements to a buffer of 8bit elements.A simple functi...
