How does one generate an output signal?
I've been playing with the demo code for our new ind.io but can't get it to raise any pins to HIGH. I'm assuming that the CH1, CH2... labels correspond to pins 0, 1... I've stripped the code down to the bare minimum writing HIGH and LOW to all the available pins. But I don't see voltage on any of the channels. What am I missing? (Code below)
#include <Indio.h>
#include <Wire.h>
void setup() {
// put your setup code here, to run once:
pinMode(0, OUTPUT);
pinMode(1, OUTPUT);
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);
pinMode(12, OUTPUT);
pinMode(14, OUTPUT);
pinMode(15, OUTPUT);
pinMode(16, OUTPUT);
pinMode(17, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(0, LOW);
digitalWrite(1, HIGH);
digitalWrite(2, LOW);
digitalWrite(3, HIGH);
digitalWrite(4, LOW);
digitalWrite(5, HIGH);
digitalWrite(6, LOW);
digitalWrite(7, HIGH);
digitalWrite(8, LOW);
digitalWrite(9, HIGH);
digitalWrite(10, LOW);
digitalWrite(11, HIGH);
digitalWrite(12, LOW);
digitalWrite(14, HIGH);
digitalWrite(15, LOW);
digitalWrite(16, HIGH);
digitalWrite(17, LOW);
}
Hi Michael,
The IND.I/O uses an expander over I2C to drive the I/O so you need to use the Indio library to access the analog and digital pins. Detailed explanation on https://github.com/Industruino/libraries#indio
Only the pins on the 14-pin IDC connector (normally used for the Ethernet module) have direct access to the MCU; they can be controlled via standard commands as in your example.
