Posted on October 11, 2012 at 09:48Good morning, i'm working with a stm32F0-Discovery board (cortex M0), i need to change the PWM pin from PA8 (using TIM1) to PC8 (using TIM3), but there is a problem because it works wrong.In the following codes i h...
Posted on December 02, 2011 at 06:03Hi everyone,I'm starting with the stm32f100rb and trying to set up the communication with 28j60(SPI). As far as know the 28j60 only support the spi mode 0 and run at frequencies of at least 8 MHz.To compile with...
Posted on October 11, 2012 at 09:31Hi everyone!I'm new to the world of microcontrollers. After some research, I bought my first ARM based Microcontroller; the STM32F4 Discovery.Now, I have a few questions for the community, hopefully someone can ans...
Posted on September 22, 2012 at 03:30I'm familiar with using alternate function inputs on the STM32F1 series; the associated GPIO pin is set as an input (CNFx[1:0], MODEx[1:0] bits), AFIO clock is enabled, and the AFIO->MAPR register is set appropri...
Posted on October 05, 2012 at 11:28Hello, Did some more tests on my TIM + DMA issue with also atollic to verify it was not the compiler. I am now pretty sure it is a hardware bug in the STM32F051. I tried almost every configuration possible, but if ...
Posted on October 10, 2012 at 19:59Hi, I am trying to connect to the STM32F103VBT6 via JTAG. I am using TIAO JTAG controller (similar to OLIMEX) with OpenOCD. JTAG itself seems to work fine. It can read ID correctly. However I can not halt the core....
Posted on September 23, 2012 at 23:13Are there any examples or application notes about how to execute a Code from internal Ram , i need to do IAP , but when programming flash from a flash based code , the controller hangs and even debugger can't ...
Posted on October 11, 2012 at 09:59Hi,my stm32f205ze controller become write protected,when i am trying to program its flash option bytes i was written all sectors write protect command. now i am unable to load the program now.what i can do to remov...
Posted on October 10, 2012 at 13:12hi guys! i want to measure the time in microseconds (better would be nano if possible) since my programm started running.. well i would try it via building a delta T (elapsedTime-startTime). The whole problem is th...
Posted on October 08, 2012 at 05:20I can get PWM output to work with my F4 MCUs, but I can't get it to work with the F0. My code is below, any ideas? As you can see, I'm not using the STM libraries, I am only using their stm32f0xx.h header for regis...
