Assistance with Waveshare 3.2 inch v4 screen

[ravenousld3341]

1. Amazing work here. Thank you!
2. I don't know where else to go with this. Hopefully you can assist. All information I have follows.

Setup a Waveshare 3.2 with Raspberry Pi 2 B

I have a raspberry Pi 2 B, a monitor Wasveshare Spotpear 3.2 inch LCD v4 OS is Raspberry, Wheezy with NOOBS_v1_4.1

USE PASTE AND COPY

1) sudo nano /usr/share/X11/xorg.conf.d/99-fbturbo.conf Option “fbdev” “/dev/fb0″ and change the fb0 to fb1

2) Download the driver for the LCD sudo REPO_URI=https://github.com/notro/rpi-firmware rpi-update sudo reboot

3) Enable SPI via raspi-config sudo raspi-config find the “Advanced Options” line find the line that says “SPI ENABLE/DISABLE AUTOMATIC LOADING“ Click enter here Enter yes and reboot sudo reboot

4) Edit the /etc/modules sudo nano /etc/modules

Add the following code below the snd-bcm2835 line

spi-bcm2708 ads7846

fbtft_device rotate=270 name=waveshare32b gpios=dc:22,reset:27 speed=48000000

fb_ili9340 width=320 height=240 buswidth=8init=-1,0xCB,0x39,0x2C,0x00,0x34,0x02,-1,0xCF,0x00,0XC1,0X30, -1,0xE8,0x85,0x00,0x78,-1,0xEA,0x00,0x00,-1,0xED,0x64,0x03,0X12,0X81, -1,0xF7,0x20,-1,0xC0,0x23,-1,0xC1,0x10,-1,0xC5,0x3e,0x28,-1,0xC7,0x86, -1,0x36,0x28,-1,0x3A,0x55,-1,0xB1,0x00,0x18,-1,0xB6,0x08,0x82,0x27, -1,0xF2,0x00,-1,0x26,0x01,-1,0xE0,0x0F,0x31,0x2B,0x0C,0x0E,0x08,0x4E,0xF1, 0x37,0x07,0x10,0x03,0x0E,0x09,0x00,-1,0XE1,0x00,0x0E,0x14,0x03,0x11,0x07, 0x31,0xC1,0x48,0x08,0x0F,0x0C,0x31,0x36,0x0F,-1,0x11,-2,120,-1,0x29,-1,0x2c,-3 "FROM fb_ili9340 UNTIL -3 ALL IN ONE LINE !!!" Remark: rotate in the line fbtft_device rotates your desktop, you can change this (90, 180, 270)

5) Edit /boot/cmdline.txt: sudo nano /boot/cmdline.txt ENTER ALL BELOW IN ONE LINE!

dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p6 rootfstype=ext4 elevator=deadline rootwait fbtft_device.custom fbtft_device.name=waveshare32b fbtft_device.gpios=dc:22,reset:27 fbtft_device.bgr=1 fbtft_device.speed=48000000 fbcon=map:10 fbcon=font:ProFont6x11 logo.nologo dma.dmachans=0x7f35 console=tty1 consoleblank=0 fbtft_device.fps=50 fbtft_device.rotate=0

6) sudo reboot

7) Activating the touchscreen sudo nano /boot/config.txt "Insert this line on the end of config.txt" dtoverlay=ads7846,speed=500000,penirq=17,swapxy=1

8) Calibation Entry, keeps the monitor steady or install xinput_calibrator

sudo nano /usr/share/X11/xorg.conf.d/99-calibration.conf

Section "InputClass"
Identifier "calibration"
MatchProduct "ADS7846 Touchscreen"
Option "Calibration" "3900 240 3900 240"
EndSection

sudo reboot

9) Gimmick :-)

sudo apt-get install mplayer wget http://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_320x180.mp4

DON'T START THE GUI WITH STARTX, STAY IN THE CONSOLE! Enter in the console mplayer -vo fbdev2:/dev/fb1 -vf scale=320:-3 BigBuckBunny_320x180.mp4

Have a nice day

I followed these directions and My screen is still all white. I've been stuck on this for 3 days.

This looks OK, however my /dev/fb1 never appeared

pi@raspberrypi:~ $ ls /dev/fb*
/dev/fb0

And I have a single error

Found the source of the issue

How do i fix this?

OK... So i corrected the error by commenting out the config lines for my screen

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

i2c-dev
spi-bcm2708
ads7846

#fbtft_device name=waveshare32b gpios=dc:22,reset:27 speed=48000000

#fb_ili9340 width=320 height=240 buswidth=8 init=-1,0xCB,0x39,0x2C,0x00,0x34,0x02,-1,0xCF,0x00,0XC1,0X30,-1,0xE8,0$

I'll just wait for some pointers. It appears that I'm missing a module for my touch screen or the config line is wrong in /etc/modules

[ravenousld3341]

Would the following commands resolve this issue?

sudo modprobe spi-bcm2708
sudo modprobe fbtft_device name=waveshare32b
export FRAMEBUFFER=/dev/fb1

[ravenousld3341]

The commands listed above didn't seem to resolve anything

[notro]

notro/rpi-firmware is deprecated, use ordinary raspian kernel. You can probably use a Device Tree overlay from here: https://github.com/swkim01/waveshare-dtoverlays

[ravenousld3341]

I'm going to reimage my sd card tonight and start over. What process would you recommend?

[notro]

I don't know anything about the Waveshare displays, except that many people have problems with them.

[ravenousld3341]

Ahhh. I see. Thanks for your time. I've engaged another user over on swkim01's github for further assistance. Thanks again!
