STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on November 18, 2013 at 07:36Hello, I am working with STM32F4 Discovery with FreeRTOS and summon arm tool chain.I am sending ADC data over serial Port using USB serial communication.I have write code to get ADC value in continuous conversion...
Posted on November 15, 2013 at 11:53Hi to everybody, doesn anyone knows if is it possible to read the pin's state when the GPIO is configured in output mode? I made a quick test, and seems not to be possible.
Posted on November 14, 2013 at 05:19Hello ForumI have some code to initialise my RTC, compiled with Keil. This code works on the MCBSTM32F400 Keil eval board, but is not working on my target hardware. The program fails on ''RTC_WaitForSynchro'' and ...
Posted on January 17, 2013 at 10:19I want to sample 1Mhz signal from stm32F4 discovery using ADC1 channel 7. I get 100Khz sample fine, but above it, sampling is not proper. how can I increase sampling rate or what can be the problem? #ampling-rat...

Posted on November 15, 2013 at 16:35I have a rather simple problem. Just trying to run the external interrupt on pin PA0 on stmf4-discovery without the library functions. It ran correctly on simulation trial using stm32f103 device. But I'm missing o...
Posted on November 17, 2013 at 15:14HiI am using an STM32 in a project as a Virtual Com Port, everything is working really well, however i would like the Virtual Com Port to appear with a custom Device Description in Windows device manager. Would an...
Posted on November 17, 2013 at 00:24Hello :)I want a timer to execute ISR all 4 ms but for academic reasons (interest) I want it as accurate as possible. So I chose TIM_Prescaler = 0 and TIM_ClockDivision = 0.Is there anything else that could increa...
Posted on November 16, 2013 at 19:21So far from the help here (mainly clive1) I got my timers running, GPIO initialized and some demo code running. The device I am trying to control is not recognizing the data I am trying to send to it so I dug a l...
