TS-7250-V3 LCD Header
The LCD header is a 0.1" pitch 2x7 header including GPIO. This is designed around compatibility with the HD44780 LCD controller which includes our LCD-LED. The LCD Data pins (7-14) are 5V tolerant. These will output up to 3.3V, and the remaining control IO and PWM are 3.3V tolerant.
- This pin is used to dynamically adjust contract on the LCD. This may need to be tuned depending on the environment or altitude where the display is used.
For example, this would write to the display:
lcdmesg "line 1" "line 2" # Messages can also be piped to lcdmesg: echo -e "line 1\nline 2\n" | lcdmesg
For example, running:
lcdmesg Technologic Systems
