Posted on October 13, 2013 at 06:46Hi,I'm trying to understand what the ADC_SMPR register is used for.According to Reference Manual we have following control on the ADC conversion time:ADC_CR1 Register:Bits 25:24 RES[1:0]: ResolutionThese bits are w...
Posted on October 08, 2013 at 00:24Hi!how do I findthe number of the first isochronous frame-odd or even? tracing shows, the host can start transmitting with both even and odd frames unpredictable. however, the frame number must be programmed in STM...
Posted on October 07, 2013 at 21:54Hi, I am using the Discovery F3, I am trying to interface with an SPI port device which requires a 32 bit transfer and 8 bits for address, in the data sheet, the data size is between 4 and 16 bits. I would know if ...
Posted on October 06, 2013 at 03:28 I'm using a DIY development board for STM32F405RGT6, with an 8MHz HSE. I've used the clock configuration tool from ST to generate the system_stm32f4xx.c file such that the clock is configured to 168MHz using t...
Posted on February 22, 2012 at 17:14Dear All, I have two separate STM32F103's communicating to each other by SPI. I've configured one as a master & the other as a slave. I'm using DMA to automate the SPI transfer. I've used the ST Library (3.5.0) e...
Posted on October 12, 2013 at 18:48Hello, in fact I've been working on the STM32F3 Discovery Board and I could generate a PWM signal. But there is still something I couldn't understand, which is how to calculate the prescaler value according to the ...
Posted on October 12, 2013 at 18:10 I want to write function using timer 2 for have millisecond in STM32F103 I just don't know why this doesn't work! TIMER2 config: void config_TIM2() { NVIC_InitTypeDef NVIC_InitStructur...
Posted on October 11, 2013 at 20:44 hi, below is the code i wrote just to change the states of pins PA10, PA11, PA12 and PA even though pin PA10 and pin PA15 gives the correct output to the functionsGPIO_SetBits() andGPIO_ResetBits(); PA11...
Posted on October 11, 2013 at 18:12thank you Cliveand just another problemwhat about structures? how should I declare and use STRUCTURE in multiple .C files?
Posted on October 03, 2013 at 07:34Hi everyone, I am currently using mb950 revA board based on STM32w108cc on some WSN demos. I have noticed that, mcu resets itself after pressing pushbutton with a duration of 4-5 seconds. (except reset button) Hav...
