Hello everyone! I have a question about PS/2 keyboard.

1. Freescale MKL27 analog PS / 2 timing to the PS / 2 keyboard to send 0xFF, not 0xFA command; in accordance with the same principle, in STM32 can indeed achieve and PS / 2 keyboard communication.
2. In the boot self-test can not identify the PS / 2 device, but I use the same code in the 51 single chip can indeed be achieved.
I realized the function on other platforms, transplanted to Freescale did not succeed, I would like to ask PS / 2 timing in the end and what? How do I get PS / 2 keyboard boot check on Freescale MKL27, how do I receive PS / 2 keyboard data and send commands to the keyboard?

We don't have any demo application for PS/2 keyboard with Kinetis products.

Sorry for that.

I do a search for some software resource about how to communication with PS/2 keyboard:

Arduino Playground - PS2Keyboard

PS2Keyboard Library, Connect a keyboard for user input

GitHub - PaulStoffregen/PS2Keyboard: PS/2 Keyboard Library for Arduino

Using a PS/2 keyboard with a Raspberry Pi

Wish it helps.

Have a great day,
Ma Hui
