OrangePi PC+ and 7inch HDMI LCD (C) from Waveshare

Hi all,

I have the Orange Pi PC+ with installed latest armbian. system installed on eMMC.

When I connect the LCD 7" ( http://www.waveshare.com/wiki/7inch_HDMI_LCD_(C) ) via hdmi to Orange Pi PC+ I only have a white screen. I do not know where I could change the settings in Armbian so that I can see the normal image on this display just like on a computer monitor. For RPi3 I knew what to do and where because it is described on wiki page for this display.  Unfortunately I do not know linux well.

Hello, I've tried anything but finally found a solution in this topic.

 

1. find your device at /boot/bin directory

2. install Sunxi-tools http://linux-sunxi.org/Sunxi-tools

3. convert binary configuration to fex format (bin2fex /boot/bin/yourdevice.bin /boot/bin/yourdevice.fex)

4. change display resolution in following sections: 

[disp_init]
disp_init_enable = 1
disp_mode = 0
screen0_output_type = 3
screen0_output_mode = 5
screen1_output_type = 3
screen1_output_mode = 5
fb0_width = 800
fb0_height = 480
fb1_width = 800
fb1_height = 480
 
[hdmi_para]
hdmi_used = 1
hdmi_x = 800
hdmi_y = 480
hdmi_power = "vcc-hdmi-18"
hdmi_cts_compatibility = 1

5. convert fex to binary format to apply the changes (fex2bin /boot/bin/yourdevice.fex /boot/bin/yourdevice.bin)

 

Boot&Enjoy!

Hello,

 

Sorry for my bad English.

 

I have Orange Pi PC+ and Waveshare 7" Touch Screen (C) like Wojtek.

 

I run latest ARMBIAN 5.30 stable Ubuntu 16.04.2 LTS 3.4.113-sun8i

 

When I use screen with RPi 3 (latest Raspbian), it fit. But when I connect screen to OPi PC+ I get only display (with tiptop's solution 1024*600).

 

I was research how to enable touch and I found lsusb command. When I use lsusb command I got this :

 

root@orangepipcplus/:# lsusb
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 

I cant find this Bus 006 Device 002: ID 0eef:0005 D-WAV Scientific Co., Ltd Vendor ID and Device ID in hid-multitouch (or etc. didnt remember) files.

 

And evtest command :

Doesnt give any output when I touch screen.

 

I can only see output with

Also in this topic shahidali55's solution doesnt work for me.

I really did a lot of thing but I didnt get any solution.

 

Can anyone know how to enable touch for Waveshare 7" Touch Screen (C) ?

I'm having the same issue as you.

 

with dmesg i get the following output:

  8.031945] hid-multitouch 0003:0EEF:0005.0001: input,hidraw0: USB HID v1.11 Device [WaveShare WaveShare Touchscreen] on usb-sunxi-ohci-1/input0

 

and I can see touch-inputs when using: xxd -c 11 /dev/hidraw0:

 

00000000: 0101 0003 2900 fb00 aa33 01

                                                        some kind of counter, increases when i hold/touch the screen

 

each byte-double is increasing its position like this: ff02 -> 0003

 

some things i found out:

 

0101 0003 2900 fb00 aa33 01  ....)....3.

touch-start/hold

 

0100 0003 2900 fb00 aa33 01  ....)....3.

touch doesn't work in normal use.

 

I'm a noob when it comes to drivers, does someone know which files I need to modify to get it working or should I emulate mouseclicks reading the outputs from: xxd -c 11 /dev/hidraw0 ?
