Hi Aravind palanisamy

Thank you for contacting us.

Is your project from our SDK or your developed by yourself?

if NXP demo code, where is link?

Anyway, please let me know how to reproduce it thus I can check it further.

Have a great day,

HAI 

plz let me know how many ports are available out of 29 pins in LPC824 CONTROLLER    

[ZhangJennie]

I guess you use LPC824 HVQFN33 package package.

this chip totally has 32pins. Vdd, Vrefp, Vrefn can't be used as GPIO.

Other 29 pins: in debug phase, SWDCLK and SWDIO are used as debug interface. if you need reset feature, PIO0_5/RESET is used as reset. others can all work for GPIO.

Have a great day,
Jun Zhang

LPC824 HVQFN33 only has one port. it's port0. there are 29 pins distributing to port0, PIO0_0 ~ PIO0_28.

plz let me know what is Hysteresis

[ZhangJennie]

GPIO feature hysteresis is to prevent spurious state changes.

Virtually all GPIO inputs use a principle called hysteresis to prevent spurious changes in state when an input value changes. “Hysteresis is the dependence of a system on not only its current environment but also on its past” (read more).

BTW, if you have new question. please open a new thread. Thanks.
