Posted on January 24, 2012 at 08:23Hi, I'm trying to communicate with Huawei 3G USB modem using STM32 Host and Device USB Library. Those modems require to be disconnected after some configuring to switch to CDC mode.Is there any way to force some U...
Posted on October 21, 2014 at 16:40 Hi, I was looking for an example about ADC with 2 input pin and I have found this code, from another old thread in this forum: #include < stdio.h > #include < stdlib.h > #include < string.h > #inclu...
Posted on October 24, 2014 at 11:59In some of the demos for FreeRTOS on cortex M0 MCUs configMINIMAL_STACK_SIZE is set to 60 while on some others it set to 70. Using the STM32Cube software it's set to 128.My question is what is actually the MINIMAL ...
Posted on October 23, 2014 at 10:51I am trying to figure out how the STM32 multiple channels ADC conversion works (regular group). Lets say I want to convert on two channels, channel 1 and channel 2, on ADC1 and the sampling rates are 1 Hz and 10 Hz...
Posted on February 21, 2013 at 15:46I meet difficulties to understand the RTC calibration protocoles presented in the UM1581, the RM0316 or the AN3371.Two distincts calibration procedures are discussed there in :- a coarse one, - a smooth one. For w...
Posted on April 22, 2014 at 08:37Hi, I am using STM32F429ZIT6 in my new design. I got a Rev.Y silicon from DIGIKEY. I found that the SDRAM cannot be used as stack or heap, and now I know there is a problem as stated ES0206 “2.8.7 FMC dynamic and sta...
Posted on October 23, 2014 at 19:20Good day,Is it possible to change system clock (PLL) during run mode.I tried to change it with this one, but does not worked:RCC->PLLCFGR = PLL_M | (PLL_N << 6) | (((PLL_P >> 1) -1) << 16) | (RCC_...

Posted on October 21, 2014 at 23:30 Hi, Its my first time here! I have a STM32F429I-DISCO, original from factory. I used the STM32CubeMX with STM32Cube_FW_F4_V1.3.0 to build a code. I selected ''new project\board selector\...
Posted on October 23, 2014 at 20:45Hello all, i want to build a function like current_time = time_now - last_time, more exactly i wanna get the time from two of the same event (reading some mems sensors) I'ved google`it a bit and found that most u...
