Hi all,

     Can anybody provide/point to the datasheet/ connection details of GD-6363P LCD used on TWR-SLCD?

Thanks,

Pramod TM

Hi Mark,

     Thanks for the answer. I'm trying to code for TWRPI_SLCD on TWR-KL25, which doesnot have a built-in LCD controller. I'm referring to http://cache.freescale.com/files/microcontrollers/doc/app_note/AN3412.pdf, http://www.utasker.com/docs/uTasker/uTasker_SLCD.pdf and http://www.atmel.com/images/doc8103.pdf for understanding. From the waveform, i gather that Vdd/2 is necessary, and we need a resistor divider on backplanes to achieve that. But on TWR board/TWRPI-SLCD board, I dont see any such resistors.

     My question here is that "is there any other way to do so?" Otherwise, i don't see a rational explanation for providing TWRPI-SLCD on TWR kits with no LCD controllers/ resistor divider?

Thanks,

Pramod TM

PS:I can solder resistor network for each of the COM pins. Just being curious.

Hi

Since the SLCD requires many lines for its control, and each has to switch at a certain frequency (and multiplex) with different analogue levels it doesn't make a lot of sense to do this in software with a chip that doesn't include an SLCD controller.

The following Kinetis include SLCD which can be simply configured and used without an processor overhead so it would be wiser to choose a suitable device rather than starting a complicated hardware/software development which will them require much of the processor's power to handle it.

- K30

- K40

- K51

- K53

- KL43

- KL46

(maybe more)

Regards

Mark
