Interrupt communication between two boards using PIN connections
Im trying to develop a parallel implementation of a microcontroller that uses two boards FRDM K64F and im trying to send a signal from one to the other connecting them both, for the first board in the D2 and other board in the D3. I´ve tried using DigitalOut in one board using the write() and assigning a 0. Additionally, i used DigitalIn in the other one, but i didnt get any results and the function read() always returned 1. Also, i used InterruptIn implementing the funtion for rise when the signal changed, but the method was called sporadically, and not when expected. I hope some one can help me or give an example of how to do it correctly. Thanks.
