Posted on December 30, 2013 at 14:15Guys, How can I read a button from GPIO PC0 ? I have created : RCC_APB2PeriphClockCmd( RCC_APB2Periph_GPIOB | RCC_APB2Periph_GPIOC | RCC_APB2Periph_GPIOE | RCC_APB2Periph_GPIOA, ENABLE); //initialize PC0 and...
Posted on December 29, 2013 at 17:13HiI want to use ADC-DMA to read 4 input of voltage. PA0, PA1, PA2 and PA4 on ADC3 IN0, IN1, IN2 and IN4.I try to modify the code samples founded in STM32F4xx-Discovery_FW_V1.0.0 for STM32F4-DISCOVERY or for STM32F...
Posted on December 30, 2013 at 05:41I think I found a serious pin conflict with the CPU being used on the STM32F429I-DISCO boards if you want use the TFT LCD and networking at the same time. The TFT LCD interface function conflicts with the only two...
Posted on December 22, 2014 at 17:00 For example: output = asinf(num1)*0/PI; //result = 60 output = output/2.0; //result = 30 output = output * PI /0; //result = 0.5235987 radians (30 degrees0 output = tanf(output); /...
Posted on December 28, 2014 at 14:44 Hello, I can't figure out why my code doesn't work! I've worked with TIM1 and everything works fine but when I change to TIM8, PC6 and PC7 are always on and the complementaries always off. Please help me out a...
Posted on December 24, 2014 at 06:38 Don't really know what else to say. I'm using uVision4.74 and RTX. Please don't suggest to switch to uVision 5 and CMSIS-RTOS RTX. This line is a part of a function that was called many times before, so it...
Posted on December 24, 2014 at 19:03According to the documentation and the release notes, it looks like I should be able to either download the binary or a rebuilt HEX file for the VirtualCOMPort project to the STM32L053 Nucleo board and then connec...
