tft_touch_shield_v1's Issues

Mega PORT redo?

The direct ports for the Arduino MEGA 2560 may not be configured properly? I'm getting no signals on pins 2-7 ...

P.S. Sorry if this is a little late. I know this product is outdated.

String and Char Overflow Glitch

If you try to print a string or char using drawstring or drawchar, after printing them, the screen will be filled with the color used to print the last char or string. The bottom 1/2cm of the screen remains black. I believe the issue only happens when the string or char runs over the edge of the screen.

Wrong software for version 1 board?

I have 20-ish of the version 1.0 Seeed-Studio boards bought through radio shack. When I first ran a class several years back I was able to locate the libraries and make the boards work. Some of the Unos from that class are still programmed so I can test these displays.

Somehow they don't work with the libraries currently posted, March 2019, and the picture here is of a 2.0 version board.

I have several of the 2.0 revision and they work fine with the 2.0 drivers.

The 2.0 libraries do not work with the 1.0 boards, and the 1.0 libraries do not work with either board version.

I'm running MacOS and using the arduino IDE 1.0, 1.04 and 1.5, all of which work fine.

Can someone please find and post the correct 1.0 drivers?
