Gerhard Reithofer 2010-05-28 The LCD-Editor simulates the display unit EA T123-I2C (http://www.lcd-module.de ) used in the microcontrollerboard halvedDISC , see: https://www.tech-edv.co.at/00_Home/20_Software/50_Freie~20Software/en/free.php
This can be useful for creating screenshots and documentation.
The TCL-Source package contains also the LCD-font bitmap definitions and the Bitmap Editor (by Keith Vetter) which has been improved by some additional functions. With this program the existing dot-matrix definitions can be changed or extended.
Sorry lvirden, but I've overwritten your original page by accident :-(

JOB Thank you gerhard. With the following snippet appended to your code, you can emulate a clock.
proc _show_time {} {
global EData Canvas
# set fmt "%d.%b,%H:%M:%S"
set fmt "%d.%b %H:%M:%S"
# ----------------------------
set tm_str [clock format [clock seconds] -format "%A,%d.%m.%Y,%H:%M:%S"]
# puts $tm_str
set tmp [split $tm_str ","]
set day [lindex $tmp 0]
set dt [lindex $tmp 1]
set tm [lindex $tmp 2]
# puts "$tm - $dt - $day"
set EData(a,0) " $tm "
set EData(c,0) {1 1 1 1 1 1 1 1 1 1 1 1}
set EData(a,1) $dt
set EData(c,1) {1 1 1 0 1 1 1 1 1 1 1 1}
set EData(a,2) " $day "
set EData(c,2) {1 1 1 1 1 1 1 1 1 1 1 1}
display_TXT $Canvas
# keep it running ...
after 1000 {_show_time}
}
_show_time
Output looks like:
