Posted on December 20, 2013 at 23:08Hi ;) I finally get all the material for build my little expansion board. I have now 16Mb External SDRAM and a Direct VGA output. We can use a 512k x 16Bits SRAM too but is not necessary , i think with a total of ...
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...
