Part Number: LAUNCHXL2-RM57L

Hi I am building a project for access control system. RM57l launchpad as hearth of Door controller device.

I build a demo but i need extra gpio and interrupt pins.I am using 2 GPIO_B pin,1 GPIO_A pin,8 HET1 pin, and 5 HET2 pin as a interrupt,there are 3 HET2 pin, 6 GPIO_B pin, and 7 GPIO_A pin but i cannot use them because they are shared by same physical pin.And also there are same pin connected different physical connection.Can i choose physical pin for HET or GPIO pins ?

and i need 56 gpio ports. Hercules has too many ports.Can i done this project just hercules board? 

Thanks.

Regards.

    Hello,

    You can configure NHET, MibSPI, SPI, etc Pins as GPIO too. The Launchpad has more than 10 regular headers which contain most of the peripheral signals. You can use all the GIOA[7:0] (GIOA_3/4 on J0/J10, others on J[8:1]) and 4 GIOB[3:0].
