Posted on August 07, 2013 at 10:35Hello, I equipped the Header of the STM32F100RB-VL Dicovery Board with some LEDs. But then I recognised that PB3 and PB4 are not working, because they have to be remapped. Since this remapping I`m not able to flash ...
Posted on August 05, 2013 at 09:43Hi,I am using the STM32F051x8,I want a timer which could interrupt every 1ms in the stop mode?But I have found the TIM can't work in the stop mode,and the RTC just happen interrupt every second. How can I do?Thanks?...
Posted on August 07, 2013 at 07:29I would like to know that is there any minimum value of AHB if USB OTG is needed?The MCU that I'm using is STM32F105/7 which is in connectivity line series.When I set my SYSCLK to 48MHz or 72MHz and AHB prescaler is...
Posted on August 07, 2013 at 03:03Hi all.In the datasheet and reference manual, it mentioned STM32L1xxRx has 1 ADC module with 20 channels. I know that 12-bit resolution, the maximal sampling rate could be up to 1Msps.My question is, if I use 5 an...
Posted on August 06, 2013 at 21:14I have begun programming the stm32f4. I made a really simple program first. It added one to r0 and stored the result in r0. Then I used STM32 ST-LINK utility to confirm that r0 is increasing. It was. I though I...
Posted on August 06, 2013 at 17:24I can not find examples in C code of how to use the SRAM of STM32F205 as Backup (as EEPROM), someone could help me. I searched the ST site and Google
Posted on August 05, 2013 at 14:58Hello;am using UART communication between 2 boards contaning STM32F3, the first send the same frame every 320 ms, and the second just receive this and make autobaud.after 2 minutes of working my MCU go into HARD-FAU...
Posted on August 06, 2013 at 14:56 Hi, I am using STM32L151VBT6 controller. The problem which i am facing is only one wake up source can wake up my MCU from Standby mode, that is either RTC alarm or wake up pin. if i used the both sources, on...
