Post subject:  T6963 and C-Control
Hi,

I' m trying to program a Toshiba t6963 controlled Display with a Conrad C- Control Microcontroller. I wrote the program with a description from Steve Lawther where step- by- step is shown how to build something like that. After the intialising (correct english?? :-)) the display shows random characters in random order. Nothing more and thats my problem. E.g. when the bit for the blinking cursor is set to one in the Display mode some characters on the Display are blinking and theres no cursor. maybe someone can help me.

thx

What size display do you have and have you set all initialization values and memory areas correctly for your display size ?

Hi Henry,

the size of the Display is 240x 64. I dont't know if that are right initialisation values for the Display. I wrote the programm with this http://www.grote.net/bascom/files/writing_software_to_control_t6963c_based_displays.pdf description. I tryed a range of values for display mode etc. but nothing happens.
the exact name for the display is Toshiba TLX- 711A. Could someone give me example- values for display-mode, text- and graphic- home and the register- settings? :?:

thx

Muddel

These values at the bottom of the page should work with TLX-711A as that was the display it was developed with:
