The Freematics 3.2″ TFT LCD Touch Display Shield is a freematics shield right?

I'm trying to figure out what pins are and are not used by this shield. The linked data sheets look like ones fro ITEAD. From what I can tell, they make the original screen but stanley made his own version with the built in sd card reader, I2C, and 2 UART inputs. I simply want to know what pins I ha...

Re: Best way to convert bmp to byte array

Sorry to edit this, I took a png, converted it to a raw file using this page (http://www.rinkydinkelectronics.com/t_i ... ter565.php) and loaded it from an external SD card.

Re: kit #3, OBD-2 "UNABLE TO CONNECT"

Why are some of these posts blank? Did this get resolved? I'm having the exact same issue with the exact same setup.

Actually I have the I2C adapter.

Re: Best way to convert bmp to byte array

I forget how I did it but the conversion was very time consuming and annoying. I wound up coding it so the bmp was read through an SD card so that conversion wasn't necessary. The file space on the Arduino itself is far too precious to be spent on bitmaps.

What's the difference between the uart V1 and V2 adapters?

The V1 (http://freematics.com/store/index.php?route=product/product&product_id=30) is $25 and the V2 (http://freematics.com/store/index.php?route=product/product&product_id=83) is $45. I don't quite get what the difference is other than the V2 is better. I have the V1 right now with my mega ...

Best way to convert bmp to byte array

I noticed the main background of the obd2 mega logger is a bmp converted to a char array. I'd like to know how to best convert a regular old bmp into this format without coding something from scratch. I can't find documentation anywhere.

Touch screen capability?

I'm using he MultiLCD library for the 3.2" touch screen LCD that comes with the OBD2 kit 3 package (http://freematics.com/store/index.php?route=product/product&product_id=70) and there doesn't seem to be touch screen capability in the library. I see documentation to use the UTFT_Button libr...
