Hi,

I want to drive TN TFT display using MC9S12XET256. Can anyone of you suggest some TN TFT displays which can be driven by this controller?

Regards,

Arthi V

Hi Arthi,

In general, there are two types of displays:

1. Pure display with a lot of front and backplane signals

2. Displays with inbuilt driver

There is application note http://www.nxp.com/files/microcontrollers/doc/app_note/AN3219.pdf

http://www.nxp.com/webapp/sps/download/license.jsp?colCode=AN3219SW

which describes principles and contain example code for pure display driving.

Note: The S12H, S12HZ, S12XHZ, S12HY, S12XHY, S12ZVH, S12ZVHY, S12ZVFP families are targeted for user interface application like dashboard or HVAC front panel. They directly use hardware module for driving these LCD displays.

The displays with an inbuilt driver are driven by serial/parallel commands and driving protocol depends on the used driver.

In attachment is example code for driving 4x20 LCD display with HD44780 driver. The example code id for S12XDP512, but the LCD driving principle is the same as for S12XE.

The slightly updated version for S12Z derivatives may be found at:

https://community.nxp.com/docs/DOC-332682

Unfortunately, I am not aware of any public available example code for driving color TFT displays by S12XE.

I hope it helps you.

Have a great day,
Radek
