Raspi TFT

[DylanM]

Hi,

I was wondering where I should get my pi 2.8 inch TFT from because adafruit is a bit iffy. And I think I saw paul with one but I'm not sure where he got it.

Thanks

Hi Dylan,

I purchased mine directly from Adafruit. Since then they have released 2.8" capacitance versions and a range of 3.5" screens at a higher price. You can now buy them from this Australian site:

http://raspberrypiaustralia.com.au/coll ... ts-add-ons

Depending on what you want to display, a cheaper option might be one of these:

http://www.dx.com/p/arduino-1-6-lcd-dis ... CnW41dVVek ; White background LED
http://www.dx.com/p/replacement-1-6-lcd ... CnW41dVVek ; blue background LED

the above LED's can do something like 5 lines of 16 characters, as well as simple graphics. They require a bit of soldering and to compile the driver, however, that might of changed since I last used them.

One last option, is the hdmipi screens. These plug into the HDMI port: http://hdmipi.com/ initially they are not coming with a touch screen, but the next version should.

There is also an official RPi display coming out later this year and should be cheaper (us$65?) than the hdmipi screen and should have a touch screen.

Apart from price, you have to look at how they connect to the RPi - SPI, I2C, UART, HDMI etc, and what kind of driver each display solution requires.

What shipping option did you use

What shipping option did you use

For what product or supplier? I use the cheapest shipping I can get. dx.com is free, but takes up to 6 weeks to arrive! Adafruit will take 2-3 weeks. The AU one might take a week or two?

I think I'll go with au

Hi Dylan,

which screen did you end up getting? If it's an Adafruit one, there is a tutorial here for it:

https://learn.adafruit.com/adafruit-pit ... spberry-pi
or
https://learn.adafruit.com/adafruit-2-8 ... tive-touch

otherwise we can chat about it on Sat. if your coming along. See the next email regarding the venue change.

Hi it's not an adafruit tft but it is resistive and the tutorial didn't help either.

Hi Dylan,

We need some more info on what you have. Do you have a link to where you bought it from or what it is? Do you know if other people have successfully added it onto a RPi?

[DylanM]

It is 2.8 inch resistive on here http://raspberrypiaustralia.com.au/coll ... ts-add-ons

Hi Dylan,

Have you got a B+ Pi ? I hear they need a tweak because of their different USB arrangement?

[parkview]

Hi Dylan,

so how far through the setup guide did you get: http://www.dfrobot.com/image/data/DFR02 ... US.1.0.pdf What errors do you have?

I see the tutorial link isn't working at the moment. Hopefully that will be fixed soon.

PS. did you try getting it going via your MAC laptop, or a Windows PC?

[DylanM]

Hi the screen is not usb instead it uses the GPIO pins. I have also contacted raspiaus for help but i have got no reply and there seems to be no instructions anywhere.

Hi Dylan,

I need more info on which product you purchased. You linked to a page with different products on it. Can you post a link to the actual product, as I think I am not looking at the correct one.

Are you getting any errors using the product? If so, you will need to post the errors, you can take a photo or post a screen shot of the error as they are all handy.

[DylanM]

http://raspberry.piaustralia.com.au/col ... tft-add-on This is the link to it. I am also going to try phoning them today.

Ah, that is clearer. You will need to load a driver for the touch screen and the LCD screen. I don't see any links to any software. The datasheet mentions this company: www.iteadstudio.com You might want to poke around there to see if you can find some links to some kernel drivers. Otherwise, yes, see if the local company knows of any drivers. You might have better luck calling during working hours?

With a bit more Googling, I found this Wiki: http://wiki.iteadstudio.com/RASPBERRY_PI_2.8_TFT_ADD-ON which leads onto this source for a driver: https://github.com/notro/fbtft

I don't think this is a beginners kind of LCD screen. You might be better of with something like the HDMIPi screen, or just wait for the official RPi touch screen to be released, but we have been waiting for that for 8 months or so already.

Hi Dylan,

this video blog by Eben, spends the first 4 minutes talking about the upcoming RPi Display: http://www.raspberrypi.org/the-raspberr ... nd-gordon/

Essentially, there was a delay while they got some other RPi models out the door, ie: RPi 2 and there has been a delay with different countries certification of the unit. He thinks it should be released by April.
