Kinetis K32 L3 supports LCD Interface for TFT LCD

[andy_kim]

Hello I would like to know if Kinetis K32 L3 supports LCD Interface for TFT LCD. When I check the MCU Selector Guide It does not seem that it supports LCD Interface. Thanks Andy

Hello,

With FlexIO you can drive TFT, it is not yet implemented in SDK but have a look at AN12685 to see an example.

Dear darknight,

Thanks for your comment,

If it is not implemented in SDK, we can not use FlexIO of K32 L3 for LCD I/F?

Thanks,

Hi, 

you can develop your own driver, or trying to use/adapt other driver : 

MCUXpresso SDK API Reference Manual: FlexIO MCU Interface LCD Driver (nxp.com)

you can find also a generic driver for sdk here :

mcux-sdk/drivers/flexio at main · NXPmicro/mcux-sdk · GitHub

Dear Darknight,

Thanks for your comment.

Can I ask you further questions for LCD segment?

As for K32 L2B,

They have Serial interface for LCD segment.

When it comes to K32 L3,

It can support LCD segment by Flex IO?

If so, what resolution of LCD segment can K32 L3 support?

Thank you ,

Andy

Hi

FlexIO supporting emulation of serial/parallel communication protocols
UART, I2C, SPI, I2S, Camera IF, LCD RGB,
PWM/Waveform generation

For LCD RGB you have possibility to transmit/receive 8 bits or 16 bits of data
