Re: SD card on ILI9341 display board??

@ag123

Thanks

I'm currently feeding 3.3 into its Vcc, and I also connected its Vcc to its LED (I soldered a strap on the back of the board)


I'm not sure if I can feed the backlight LED with 5V or not

Thanks

I presume it is defaulting to SPI1

Re: Connecting Nextion display to Nucleo L432KC

STlink for programming is not serial, its a different set of connections and a different protocol

Re: Analog pins definition

Thanks Daniel.
I looked at my Nucleo boards but I don't have either of those variants

Re: SD card on ILI9341 display board??

Thanks Chris

BTW. Did you connect the SD to SPI 2 or share with the display on SPI 1?

Re: OV7670, Generic STM32F103RC and ILI9341 display

First of all, I'm not sure why this is working, but I promise you it is ;-) I change my code, so that I byte swap and duplicate the pixels down the line, and also send the same line to the display twice uint8_t dispBuf[320*2]; uint8_t b1; uint8_t *tdBufEnd = dispBuf + 320*2; void sendLineToDisplay()...

Re: SD card on ILI9341 display board??

can i ask for before & after pics? srp Not sure what you mean. They are just small SMD resistors on the back of the display PCB. I think I can solder bridge them even without using a small piece of wire (probably) and if not, I'll just use a small strand of copper wire from puled out of the middle ...

Re: OV7670, Generic STM32F103RC and ILI9341 display

I tried compiling with -O2 instead of -Os and it didnt make the display any better, however the code speed must be a lot faster because I'm now only seeing 2 images vertically on the screen, instead of 4 Also, if I byteswap I do get better colours, but it looks like there is something strange going ...

Yes and some other provided with libraries.
Moreover, as I said Firmata need this.

That's why I try to fit Arduino naming.
Ah OK.

I see I need for it :-(

SD card on ILI9341 display board??

Guys Just a quick question.. Has anyone used the SD card on the ILI9341 display board. It looks like it has resistors in series with the data lines, which is possibly to make it compatible with 5V systems. I am going to short these on my board and give it a try, but I wondered if there were any othe...
