Posted on January 25, 2012 at 14:44I am learning how STM32 works. I looked at startup file and starup vector using simulator and example project. And I have question (STM32F105): 1. First dword location of vector is stack pointer and it is initializ...
Posted on January 24, 2012 at 12:00Hello I am looking for a TCP / IP stack that integrates affordable DCHPclient, ''FTP client'' and filesystem. Ported to a STM32F4xx. LwIP not implemented. NicheLITE requires additional packages. Price? Open-source...
Posted on January 23, 2012 at 11:02I need all four channels on TIM5 for input capture. According to the data sheet, TIM5_CH1 is available on PA0. On PH10, a signal called TIM5_CH1_ETR is available. Can I use this pin as a normal channel 1 input, or ...
Posted on January 23, 2012 at 17:49Hi,I am trying to get the usart to work on the olimex stm32-p107 board. I setup the GPIO ports and USART, but cannot seem to send, or receive any data. Has anyone has this problem? or any ideas? Here is my code: R...
Posted on May 01, 2011 at 19:54I am new to ARM. I got the STM32 Discovery board. (STM32F103RGT6 chip) I made a quick code that uses the serial port.(code I copied from Keil website that uses the serial port, and just modified very slightly so it al...
Posted on January 17, 2012 at 17:30I'm using the standard periphery library for this board. The DMA is working correctly in combination with DAC (memory to peripheral transfer) but I can't get the cpu to execute the interrupt handler for DMA1_Stream...
Posted on January 23, 2012 at 18:50I have an STM32F4 Discovery board; recently I just had uploaded some code pertaining to the PWM example where I made PD12-15 some PWM signal so I could see it working with the LEDs on board. The program uploaded an...
Posted on January 22, 2012 at 21:00I'd like to see some sample code (or a link to it) that utilizes a timer fed by an external clock, not the system clock, to generate an output pulse. All ST's sample code that I've seen so far uses the system cloc...
Posted on January 20, 2012 at 04:54I've seen figures quoting speeds of over 7.2 MSample/sec, when using triple ADC a 36MHz ADClock, and DMA. However, at those speeds (by my calculations) the effect of RADC on the input sample circuit means you lose ...
