Nṣiṣẹ pẹlu Rasipibẹri Pi Hardware Asopọ

  1. Lo okun 15PIN FPC lati so wiwo DSI ti 8inch DSI LCD si wiwo DSI ti Rasipibẹri Pi.
  2. Fun irọrun ti lilo, o le so Rasipibẹri Pi si ẹhin 8-inch DSI LCD ti o wa titi pẹlu awọn skru, ati pejọ awọn ọwọn bàbà. (Ni wiwo Rasipibẹri Pi GPIO yoo ṣe agbara LCD nipasẹ pin pogo).

Software Eto

Fi awọn ila wọnyi kun si config.txt file ti o wa ninu iwe ilana root ti kaadi TF:

Agbara lori Rasipibẹri Pi ki o duro fun iṣẹju diẹ titi ti LCD yoo fi han deede. Iṣẹ ifọwọkan yẹ ki o tun ṣiṣẹ lẹhin ti eto bẹrẹ.

Backlight Iṣakoso

Imọlẹ ina ẹhin le jẹ iṣakoso nipasẹ titẹ awọn aṣẹ wọnyi sinu ebute naa:

echo X > /sys/class/backlight/10-0045/brightness

Ibi ti X tọkasi eyikeyi nọmba lati 0 to 255. 0 tumo si awọn backlight ni dudu julọ, ati 255 tumo si awọn backlight ni imọlẹ julọ.
Ni omiiran, o le ṣe igbasilẹ ati fi sori ẹrọ ohun elo Imọlẹ ti a pese nipasẹ Waveshare fun eto Rasipibẹri Pi OS:
