Posted on September 19, 2013 at 15:57Hi all,I have trouble with RTC on STM32VLDISCOVERY board.After initialization, when I'm calling RTC_WaitForLastTask() after RTC_SetCounter() function, the MCU falls into an infinite loop.I can't get what is wrong...
Posted on September 18, 2013 at 11:58Hello,I want to protect my ADCs from overvoltage and ESD, and limiting the input to 3.3V.This is my schematic:There is a voltage divisor to convert 5V > 3.3V. The top resistor is also used as the diode resistor...
Posted on September 19, 2013 at 11:43Simple question. Hard to find any information about this. In the data sheet there are tables where ART is disabled and where it is enabled. But no more information at all around the ART concept. Regards, rygelxvi
Posted on September 16, 2013 at 10:04HelloI am working on STM32F4 Discovery .I have write code for ADC for STM32F4 Discovery (with FreeRTOS) and load ,debug using GNU tool-chain.Now I have to get that ADC data on another USB (i.e USER_USB port on S...
Posted on September 19, 2013 at 07:19I am connecting a external terminal device which communicate with STM32f2. Sometimes device is shut off which remove poer from stm32 but termial device remained powered which gives high 3.3V on device, will it da...

Posted on September 16, 2013 at 12:18Hi, I recently purchased STM32F2 eval board for STM32F207IGH6. It comes with a preloaded demo firmware. There is no user manual and no cd containing the source code of example firmware. How can I get the demo fi...
Posted on September 18, 2013 at 08:36I'm using STM studio to debug a STM32VLDISCOVERY kit. I have based is on the systimer example project where every 1ms I read some adc values. When graphing the adc returns (which are scaled) in stm studio I will ...
Posted on June 23, 2011 at 13:58Hi, I convert two adc channels(1,2) and using DMA to transfer them to memory. ADC channel1 -> MemConvertedValue[0] ADC channel2 -> MemConvertedValue[1] Normaly it works OK, but while i am in debug mode and ocusenly pr...
Posted on September 16, 2013 at 08:40Dear All, I am working on SDIO interface of STM32F4_discovery board using mass storage class example (dated: 05-March-2012). By going through different posts (special thanks to clive1) i have now b...
