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...
Posted on August 04, 2013 at 18:52 I am trying to get ADC regular dual mode with external trigger on timer 1 to work. I have read a lot of posts on this forum about ADC dual mode and some on external triggering, but I still can't get it to work. ...
Posted on August 07, 2013 at 12:43Hello Is it possible to transmit and receive audio packet using ember pro stack with STM32w108cb RF micro-controller .? If yes then please tell me the process. Shakti.
Posted on August 07, 2013 at 10:35Hello, I equipped the Header of the STM32F100RB-VL Dicovery Board with some LEDs. But then I recognised that PB3 and PB4 are not working, because they have to be remapped. Since this remapping I`m not able to flash ...
Posted on August 05, 2013 at 09:43Hi,I am using the STM32F051x8,I want a timer which could interrupt every 1ms in the stop mode?But I have found the TIM can't work in the stop mode,and the RTC just happen interrupt every second. How can I do?Thanks?...
