RE: anyone know how to program LCD with KS0070B controller

Hi,

You might want to see the data sheet on the KS0070B driver chip at

http://www.asamicros.com/pub/project_source/ks0070b.pdf

The commands for programming start at page 12 of the pdf file. Its a matter of sending the correct sequence of binary 1's (+5v) to the controller.
As an example 00000001 will clear the display
and 00000010 will return the cursor to the home position.

Any help ?, yes no let me know.

Regards

thnak you for the help Laffalot, i managed to do it but one thing is the screen of the lcd while displaying the chracters kept on flickering or keep on refreshing ...and it is rather significant ...do anyone know why and how to solve this problem...?

RE: anyone know how to program LCD with KS0070B controller

Hi,

1. It could be your program. Are you sending the characters over & over. You only need send them the once and they should get stored in the LCD RAM.

2. It could be a faulty LCD module. Have you tried any others.

Any help ?, yes no let me know.

Regards

A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
