PiScreen2 + Raspberry Pi3 display not working

[krish05]

Hi Mark,

I have received the PiScreen2 kit with ILI9486 from Tindie, and after enabling the “piscree2r” + reboot with backlight switch on the backlight is visible, but only a white background is shown.

I’m running the OS as followinf in config.txt

# For more options and information see
# http://www.raspberrypi.org/documentation/configuration/config-txt.md
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default “safe” mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display’s size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

# NOOBS Auto-generated Settings:
hdmi_force_hotplug=1
dtparam=spi=on
dtparam=i2c_arm=on
enable_uart=1
dtoverlay=piscreen2r

Following is the log after upgrading the OS and enabling the drivers:

I’m running this on a Raspberry Pi 3 with Raspbian:

root@raspberrypi:/# uname -a
Linux raspberrypi 4.4.13-v7+ #894 SMP Mon Jun 13 13:13:27 BST 2016
armv7l GNU/Linux

Looking in the forum here https://ozzmaker.com/forums/topic/piscreen-does-not-work/ i saw that the old driver mode used the following init sequence for the display:

flexfb width=320 height=480 regwidth=16 init=-1,0xb0,0x0,-1,0×11,-2,250,-1,0x3A,0x55,-1,0×36,0x28,-1,0xC2,0x44,-1,0xC5,0x00,0x00,0x0,0x0,-1,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-1,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0×11,-1,0X29,-3

I did not try to set this configuration (old driver mode) to avoid configuring in a bad state the display and breaking it apart.

While trying to debug the issue i added the following notes to that display initialization sequence that i’m sending you here:

What is the Brand/Model and Part Number of the Display ?
Do you have the Datasheet of the LCD/Touchscreen ?
Can you send it to me ?
If you don’t have it, who provided you the initialization codes ?

I can try to perfom some tests with differnt configurations but i need the full documentation that the manifacturer should provide.

Sorry for the question but did you test the display/piscreen kit before sending ?

Thank you very much,
Best Regards

Hi Chris, the IC for the TFT is ILI9488 and we corrected the description on the Tindie page a week ago. sorry for the confus
ion.
Here is the datasheet for the ILI4988;
https://ozzmaker.com/piscreen/ILI9488_Preliminary_DS_V090.pdf

You can see the init sequeince here in the overlay;
https://github.com/raspberrypi/linux/blob/rpi-4.4.y/arch/arm/boot/dts/overlays/piscreen2r-overlay.dts
Here it is for FBTFT;

sudo modprobe flexfb width=320 height=480 regwidth=16 init=\

sudo modprobe fbtft_device debug=3 rotate=90 name=flexfb speed=64000000 gpios=reset:25,dc:24,led:22

Every PiScreen is tested before we package up. We test the display and touch.

Can you disable SPI. In config.txt, place a # in font of
dtparam=spi=on

Add back the piscreen2 overlay;
dtoverlay=piscreen2r

If it still doesn’t work, please show me the output ofsudo vcdbg log msg

Hi Mark,

Thanks for replying so fast.

I tried:

1) disable dtparam=spi=on and dtoverlay=piscreen2r

2) reboot

3) enable dtoverlay=piscreen2r

4) reboot

5) send test image:

pi@raspberrypi ~ $ wget https://ozzmaker.com/piscreen/image-test.gif
pi@raspberrypi ~ $ sudo fbi -noverbose -T 1 -a -d /dev/fb1 image-test.gif

but nothing happens on the display, instead on the HDMI/TV i see the shell going fullscreen until the pression of a key then goes back normal.

Here is the log you requested after doing such tests:

Hi Chris
everything looks correct.
So it does indeed look faulty.Maybe something happened to your display in transit??

can you send your original receipt to sales@ozzmaker.com and we will send you out a new one.

Mark --OzzMaker.com --

[krish05]

Hi Mark,

Thanks for you support and excellent communication also when dealing with issues.

The kit from Ozzmaker is really nice, it includes the pens and the case that really looks good..
i’m looking forward to make the Piscreen work !

The box didn’t look like it was damaged during shipping, everything seemed also very nicely packed.

During some past tests i experienced a very fast single blinking on the screen when sending the test image, which happens to be random on a number of different tries.

The display also goes in sleep mode automatically by diminishing the light at the same time as the HDMI/TV screen.

I don’t know if those detailes are useful somehow.

In the end it looks like the LCD/Touch is not properly initialized or i don’t know what’s going on with it.

I forwarded the receipt mail from Tindie to the ozzmaker mail you indicated.

Let me know if i can do some other tests in the meantime, maybe having the LCD datasheet (not the ILITEK controller one which i already had) could help in debuggining any issues with the init_sequence for this specific LCD.

Thank you very much,
Best Regards

Chris

Hi….I remember running Ardurover on a vanilla raspbian jessie image some time ago. Ardurover does not need fast stabilization calculations, so it worked alright. I did this with a Navio+ and I do not know if the Navio2 needs further changes to support the RCIO chip.
