Posted on December 30, 2013 at 14:52I found a LCD with OTA5182A driver in SPI & RGB interface. However its RGB is serial RGB not parallel RGB in STM32F429. Is there a way to allow the LCD controller to work with STM32F429 inside lcd display? #int...
Posted on December 31, 2013 at 16:40I am trying to make USB works on Sony SmartWatch with STM32F205RG. I don't have scheme but I am 90% sure that watch uses PA11/12 for USB FS. I addopted ST's USB FS library and currently I have this : - watch is de...
Posted on November 30, 2012 at 13:21Hi , Is it possible to read a qr code through a cmos camera and subsequently decode it with stm32 ?I search through google and did not see any relevant links. Can any one provide a guide or a link ?Thanks
Posted on February 25, 2012 at 10:34hi, I am using STM32VL board.. In my application i am reading voltage for every 6.25micro sec. so i'm using timer TIM2 in interupt mode for that. can any one tell me what value i need to set fro prescaler and peri...
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...
