• I want to put a GPIO pin in high impedance mode at boot up time

• After 1 second Then i want to pull this GPIO pin to ground so that value is 0 for atleast 2ms(slave device resets)

• Then i want to put it back in high impedance mode again

can some one tell me how i can achieve this can some one give me example code i am using Arduino ide and pin mode in Arduino ide has
INPUT,OUTPUT, INPUT_PULLUP.

Moved to the Arduino subforum as you seem to want a solution specifically to that SDK.

Are you using freeRTOS?

something like, if not using freeRTOS, set pin 1 or 0, delayMicroseconds(x), set pin 1 or 0?
