General purpose input output GPIO is same thing you find in any microcontroller like , avr etc. In port0,. Also this port has many alternate functions like In port1,.

Only P1. How to program ports? There are 4 resisters you need to understand to access these ports. The current state of the GPIO configured port pins can always be read from this register, regardless of pin direction.

Writing ones produces highs at the corresponding port pins. Writing zeroes has no effect. This register individually controls the direction of each port pin. Register controls the state of output pins. Writing ones produces lows at the. My development board has an LED at P0. Remember writing 0 to any bit of IOSET0 have no effect on port pin but writing 1 will produce high on corresponding port pin. Remember writing 0 to any bit of IOCLR0 have no effect on port pin but writing 1 will produce low on corresponding port pin.

This operator shifts the value on its left side to left by 1 bit by the value specified on its right side. Well there is register like P0 in ARM. My development board has a button on P0. Error: You don't have JavaScript enabled.
