Posted on August 08, 2013 at 12:28I need to adjust the STM32F303 ADC sample time to fit to the internal OpAmp. I can't find any specification of the OpAmps output impedance to take it in account as R AIN for the sampling time table #66 in the data s...
Posted on August 07, 2013 at 23:41I have a STM32 Discovery Kit. I have set up the IAR compiler. Succesfully compiled code. However when I try to download the the Discovery Board I get the following message... Wed Aug 07, 2013 14:21:48: Fatal erro...
Posted on August 07, 2013 at 10:12Can you help me a little bit?My thesis is about writing the code for image compression and decompression on STM32F103VET6. I have a RGB file and my tasks are writing 1 code to convert the RGB to a JPEG and writing 1...
Posted on August 08, 2013 at 16:42Hi,I've bought those two boards, but for about 20s DM-STF4BB was rotated 180 deg. so +5V and +3V3 goes somewhere where shouldn't. Do you think DM-STF4BB survived?Second question: from where I can download examples f...
Posted on August 05, 2013 at 12:10 Hello, I am trying to connect two boards using I2C. I have already configured one as master but whenever I send the start condition the I2C bus is busy. Maybe I am wrong in the initialization of the GPIO...
Posted on August 08, 2013 at 08:37 Hi , I want to add a new interrupt to the system , i know that the NVIC can support up to 256 interrupts , currently in my evaluation boad ( stm32f4g-eval) there are only 81 used . So i added a new on...
Posted on August 08, 2013 at 10:46Hi, i am using STM32F303 and I use ADC1 and ADC3, sometimes ADC3 doeset work Do I need to enable dual adc or is this recquired when ADC1 and ADC2 are used tnx
Posted on August 01, 2013 at 03:43Howdy, So I enabled DMA1, on STM32F103, copying two 32-bit words (set and clear PF.15) from flash to GPIOF->BSRR at 25kHz. I then run this code with all interrupts disabled while(1) { GPIOF->BSRR = 1 << 14;...
Posted on August 07, 2013 at 20:14Can someone please point me in the right direction to use TIM2 or TIM5 as just a free running 32-bit counter, ticking at 1us, that I can read anywhere in my pgm. No I/O or interrupts desired. None of the examples i...
Posted on August 07, 2013 at 07:12Im using usart2 and i know its sending data but will not receive im using :rx_data = USART_ReceiveData(USART2);to save the data then using a while(rx_data > 0 ) { do stuff}any suggestions about why its not receiving...
