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...

Posted on August 05, 2013 at 18:16 I have an application that is working fine when I have a hardware reset (pulling NRST low) but when it is power cycled, or has a software reset (NVIC_SystemReset();) It gets hung up on the following functions: ...
Posted on March 15, 2013 at 17:50I have installed DfuSe Demo (v3.0.0) . On connecting a STM3200G-EVAL board & setting the boot options & then pressing reset, the program says I am in DFU mode and gives the Vendor Id 0483 and the Product ID DF11 and ...
Posted on August 05, 2013 at 15:02Hello, I am a new starter of STM32. I'm quite confused by the concepts of Channels and Streams while dealing with DMA. What is the difference between them? Any comments will be appreciated, cheers. #dma-stm32f4di...
