Odometer
Using the script box, it's possible to control the LCD without using the buttons above. Provided are some functions to send the LCD instructions and data so that it's easier to experiment with. These can be combined with JavaScript experssions if needed. Here are the functions: instr(instructionCode) // sends instruction data(caharacterCode) // sends data mcl(x_times) // move cusror left mcr(x_times) // move cursor right sdl(x_times) // shift display left sdr(x_times) // shift display right DDRadrs(address) // set DDRAM address CGRadrs(address) // set CGRAM address putstr('string') // print string There is also a script to define some custom characters. The odometer script runs only with Opera 5.12 on Windows. It may run on Netscape, but the browser may crash.
