Posted on November 17, 2015 at 09:58Hi guys I referred to the timer 3 channels remapped to port C for STM32F030R8. The datasheet DM00088500 version 2 page 30 did not mention there is a restriction for the mapping, while page 37 do carry a small (1) ...
Posted on November 17, 2015 at 18:55In document DM00108282.pdf(RM0377) page 143 it mentions V CORE domain clocks. What clocks are included in V Core domain? What clocks are included in Vdd domain?
Posted on May 20, 2013 at 10:56Please do this after every read of the date register ( get_date() function )(void) RTC->DR;this will unfreeze the date register so that it get updates on every read #rtc-date
Posted on November 16, 2015 at 11:38Hello everybody,I'm new on the forum and on ST microcontrollers.I'm trying to program the USART in assembly, but I have some issue to write on DR.What am I missing? Somebody can help me, please?*******************...
Posted on November 18, 2015 at 08:18Hi 1. Can a UART receive interrupt wake the STM32 MCU from Stop mode (RX line start bit) ? 2. Only a External Interrupt can wake the STM32 MCU from low power modes ? Regards #!stm32f4-disco #low-power-stop-mode
Posted on November 17, 2015 at 15:09Hello,It seems that the IRQ handler for the wakeup does not trigger even the RTC is running correctly, WUTIE is set in CR register and the ISR flag WUTF is set as expected. What could be the issue? The FW is build...
Posted on November 17, 2015 at 23:37Greetings,I'm wanting to shave every bit of power I can off of this board and was thinking of de-soldering the Boot0 and Boot1 bridges. Question is, will this adversely effect the bootloader in any way? Currentl...
Posted on November 11, 2015 at 20:08Hi, I don't know why this code doesn't work. I have following simple code to check USART and the code is running on STM32F072 discovery board. But when I check PA2 pin with scope, it shows nothing. I also connect ...
Posted on May 18, 2013 at 00:23Since 4 day I'm trying write code which will be able to count external pulses. I tried to use encoder mode but i supposed that this work only with 2 quadrature encoders. I have only one pulse signal and i have no idea ...
