Displays

Well, I was looking at displays.. I think I might bite the bullet and go with this

Sainsmart 9" TFT touch screen (1024x600 resolution)
Raspberry Pi 2B, 900mhz, 1gb ram, quad core.. 100mbit ethernet
OR
Banana pi M2 1ghz 1gb quad core, gigabit ethernet/wifi.. I'm torn!

1 case


So my idea is to mount the Pi box somewhere under the dash, by the stereo, and have the Arduino relay the information over serial port to it... The Pi will take care of all the displaying.. The reason I'm torn between the two models is that SATA would be awesome with a SSD... Store music, etc, My head unit has aux in, so now the Pi would take care of all that, and could even play warning sounds if something goes funky (EGT, turbine speed.. etc)  It has Wifi and ethernet. 

There is an expansion card that provides SATA, Wifi and a bunch of other stuff..

I could be all said and done for under $200.. plus another year of steep learnings curves to learn how to make it do what I want!

I'm like a kid at a candy store.. with $.25



edit Here's a link to a complete system.. Arduino Mega 2560 + 3.2" TFT display.. for $33.41.. I'd think that's a really good (cheap) start, and has the bonus of lots of IO's

This is what i wanted to do but with a smaller display

Rx7man

it's kinda what I was thinking (the smaller display), but if I want to be able to read gauges while driving easily, it's going to have to be a decent size.. and since the Pi is basically a full featured computer, capable of keyboard and mouse, I'll make full use of it and completely eliminate the need for a laptop... Even more cool factor than having a laptop is having a truck with one built in!

Hmmm..

*very* interesting to me... I used to be able to run BSD, Linux, etc, but I've forgotten it all.. it's been 10 years since I fiddled with it.. So a Pi running Windows 10? well.. I'd rather Win7, but I'll give it a shot, it means I can program in VB which I'm much much more skilled at and is the language I "think" in.. my C++ has to get translated, and a lot can get lost in translation as you know.  It would actually make it so I don't need to take my laptop into town to download stuff off the net..

Yeah, it's a whole bunch of gimmickry, especially considering this is a 'work truck'... With Remote Desktop Connection, I can do my programming on the truck from across the world.

Can't watch videos from here, but I'll try and look it up when I get a decent connection.

Windows IOT is kinda a waste, IMHO. It isn't what you think its strictly DEV

I'll have to look into it more I s'pose... Will be interesting anyhow.  I'm also going to compare the BeagleBone boards, and look into the NetDuino again and see which ones give me the best processing power and peripherals for the price.

I gotta say  the Raspberry Pi and Banana Pi with the X300 expansion boards don't leave very much to be desired!

I'm just asking a question on the Bpi boards about if the x300 expansion board (for r-pi) is compatible.. that would be the cat's meow.. 4 core is what the R-pi is missing

yeah you can get raspberrypie with win 10 iot on sd card. The part that surprised me is they have code on GitHub for arduino. to talk to iot. The iot is for maker builders.

I find Arduino's good for simple controls, and for most IoT, that's all that's needed... they lack the grunt to be able to compute fast enough to do displays, etc.. I mean 16mhz vs 4x1Ghz is a whole lot of difference.

On the ms3 forum guys are using teensy for there displays over can bus. They say the cost is comparable to Arduino with can bus shield.

Rx7man

It all depends on how nice a display you want, and what you want it to be able to do... full color graphic touch screens just need more oomph behind them.. The R-pi is actually pretty cheap, the 4x1ghz M2 is under $50... Add the expansion card and you have HDMI, audio, SATA, MicroSD, Camera inputs, etc... I think the CPU actually has 1 or 2 CAN bus channels, so you'd just need to hook the transceiver onto it... 
I think I'll get most of my arduino stuff settled before I go jumping into learning that... I am getting a small touchscreen display with an extra Mega 2560 I'm going to play with a little.. I know I can always find a use for the Mega, and it will help me since I can do all my programming on my desktop and have an identical copy of the program on the truck, and see how it performs.
