RTOS/TM4C123GH6PM: QEI multiplexing

Part Number:TM4C123GH6PM

Tool/software: TI-RTOS

Dear all,

I'm using TM4C123GH6PM,CCSv8.1.0,TI-RTOS - 2.16.00.08

As per my project requirement I have to use 8 QEI's. But TM4C123GH6PM is capable of 2 QEI . Is there any possibility of making normal GPIO pins as QEI capable for remaining 6 QEI. If not how can I over come this problem. Please suggest me a solution in this.

I have tried with multiplexing 4 motor's Hall sensors to QEI0 and other 4 Motor's Hall sensors to QEI1.
But for some reason my multiplex is not working.

I'm trying for last 10 days to solve this problem but i haven't got desired solution .(Now thinking that I'm going in a wrong way).
Really your help is required to solve this.

Thanks in Advance

Regards,

Yashwanth Kumar Gandeti
