Posted on December 29, 2013 at 18:57Hi, I'm fairly new to embedded system programming and I've just started experimenting with the 32f4 and 32f3 discovery boards. I'm working with a simple interrupt driven timer to flash one of the LEDs at 1Hz, but...
Posted on December 30, 2013 at 19:42Is it safe to drill the f4discovery board? For example around the SWD connector or the ST logo? I need to connect the discovery with a 10x10 expansion board I am designing. I am probably planning to have my board...
Posted on December 23, 2013 at 17:09 Hi everybody, I'm using the DAC1 output on my STM32F Up to a 12 bits values of around 1000, it works correctly, but after, the output voltage still be at 1.8V (whatever my value to be converted : 3000,...
Posted on December 24, 2013 at 08:25Hello all,Long time lurker, first time poster. I've spent the past couple days working on a board designed aroumd a STM32F100RB processor, attempting to use ADC1 to scan a group of channels via DMA. I've followed ...
Posted on December 30, 2013 at 11:32Hello! I have a STM32L151CB and I need to use the UART interface. At first it worked perfectly, but after I changed the system clock from HSI (16 MHz) to MSI (2 MHz) I only receive some characters. E.g. when I sen...

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); /...
