Looking for a specific recommendation for a dashboard display in a convertible... It's not the primary display but I am hoping for something that could be read in an open topped car - although perhaps in DIRECT sunlight might be a bit of an ask - although if possible (OLED?) then I'd love to get specific suggestions.

 

Sizewise it's probably needing to be 4:3 and perhaps 3.8 inches to 6 inches in size.

 

In a perfect world, I2C and simple programming would be great as well.

 

Hit me with suggestions... (Yes I am considering the 4Duino but it's probably more than I want to spend plus I have a pile of NodeMCUs I should use.

 

Cheers - N

I'm building a tyre and brake temp monitoring system (See terrible vertical video below) and now the tricky bit (making sure I could reprogram the I2C addresses on the sensors to have many on the bus) is done, I am looking at display options for use while racing.

[HAH! - Found the last time I just said Stuff It and pasted the link. That works for me]

Ultimately I'd like a graphical colour coded display as well as numbers (and logging to SD with time and GPS stamps) so I would like a graphical display large enough to read test, with good (enough) colour and brightness to be see in the open.

 

Cheers - N

You could have a look at the crystalfontz lcds. They're driven over serial or SPI. Not sure if they have i2c.
They show ASCII but you can store custom characters too.
They've got a zillion sizes and colours to choose from.

You just put the video id between the youtube tags and it works when I last did it?

Can't say i play with displays all that often, normally i pipe it to ELK stack to display.

 

 

 

Interesting project though, keen on following along  :)

Not sure if you've seen this guys OLEDiUNO products, but some of them sound similar to what you're trying to achieve.

 

 

 

His online store is quite often out of stock, luckily for my bank balance, but he makes a good number of custom setups for people as well.

Yep I have seen them and they look nice... As it happens I have bought a few different 20*4 LCD displays including one that's pretty large. I'm going to get the product working on a text display because it's so simple and then look at upgrading the screen later.

 

 

 

These might be suitable except they are individually so small that I'd have to put several together and that is more complex/expensive than I was hoping for.
