Here's the 7seg redone on one board with all wires in place.
I'm sure we can keep improving it, but I'm still at a loss for what could possibly be prohibiting at least some expected behavior.
Current behavior is that it goes on for a second, then off forever.
Here's the current code:
byte data = 11;
byte clk = 13;
byte latch = 10;
byte status = 13;
byte max_noop = 0x00;
byte max_d0 = 0x01;
byte max_d1 = 0x02;
byte max_d2 = 0x03;
byte max_d3 = 0x04;
byte max_d4 = 0x05;
byte max_d5 = 0x06;
byte max_d6 = 0x07;
byte max_d7 = 0x08;
byte max_decode_mode = 0x09;
byte max_intensity = 0x0A;
byte max_scan_limit = 0x0B;
byte max_shutdown = 0x0C;
byte max_test = 0x0F;
void output(byte address, byte data) {
digitalWrite(clk, LOW);
shiftOut(data, clk, MSBFIRST, address);
shiftOut(data, clk, MSBFIRST, data);
digitalWrite(latch, HIGH);
digitalWrite(latch, LOW);
}
void setup() {
Serial.begin(9600);
pinMode(data, OUTPUT);
pinMode(clk, OUTPUT);
pinMode(latch, OUTPUT);
pinMode(status, OUTPUT);
digitalWrite(data, LOW);
digitalWrite(clk, LOW);
digitalWrite(latch, LOW);
output(max_shutdown, 0x01);
output(max_decode_mode, 0x00);
output(max_scan_limit, 0x01);
}
void loop() {
output(max_d0, HIGH);
delay(1000);
output(max_d0, LOW);
delay(1000);
}
