The question about SLCD of KL36

[小勇邹]

The driver method of the LCD is 1/4 BIAS. But the diver method of the KL36 is 1/3 BIAS. Can the KL36 be used to drive the LCD? What is the parameter “1/3 BIAS” used for?

Hi Robin,

well, there is not direct driver KL36. However, you can make an inspration from KSDK 2.0 for KL43, and look for slcd driver example:

...KSDK_2.0\boards\frdmkl43z\driver_examples\slcd\

the slcd module is pretty similar to KL36, so I guess it would not time lot of time to port it. However,, it really depends on LCD selection. We have support only for SLCD you can find on FRDM-KL43 or FRDM-KL46.

Hi

The SLCD's user's manual should show the basic configuration that is required and, once connected, it is best to play around with the settings to find the most suitable anyway.

The following documents explains operation and configuration of various SLCDs: http://www.utasker.com/docs/uTasker/uTasker_SLCD.pdf

Hello,

the bias represents how many voltage levels appears in LCD waveform generation, In 1/3 bias there are 0V, 1/3V, 2/3V, V voltage levels in LCD waveform.

So, I do not think it will work on 1/4 LCD.

Hi,

Thank you for your help.

I am working on KL36 and I need driver code for SLCD. Is there any SLCD driver code example for KL36.

thank you!
