Ah! now i understand… i hope!
I do this:
void OpenSprinkler::begin() {
pinMode(GPIO17, OUTPUT); // pump
digitalWrite(GPIO17, LOW);
pinMode(GPIO18, OUTPUT); // sprinkler 1
digitalWrite(GPIO18, LOW);
pinMode(GPIO22, OUTPUT); // sprinkler 2
digitalWrite(GPIO22, LOW);
pinMode(GPIO27, OUTPUT); // sprinkler 3
digitalWrite(GPIO27, LOW);
// shift register setup
// pinMode(PIN_SR_OE, OUTPUT);
// pull shift register OE high to disable output
// digitalWrite(PIN_SR_OE, HIGH);
// pinMode(PIN_SR_LATCH, OUTPUT);
// digitalWrite(PIN_SR_LATCH, HIGH);
// pinMode(PIN_SR_CLOCK, OUTPUT);
// pinMode(PIN_SR_DATA, OUTPUT);
// Reset all stations
clear_all_station_bits();
apply_all_station_bits();
// pull shift register OE low to enable output
// digitalWrite(PIN_SR_OE, LOW);
// Rain sensor port set up
pinMode(PIN_RAINSENSOR, INPUT);
#if defined(ARDUINO)
digitalWrite(PIN_RAINSENSOR, HIGH); // enabled internal pullup
…….. continue
and:
void OpenSprinkler::apply_all_station_bits() {
byte brd_bits = station_bits[0]; // brd_bits stores the status of the first 8 stations, i.e. those on the main controller
digitalWrite(GPIO17, brd_bits & 0x01); // assigns the status of the first station to GPIO17 for the pump
digitalWrite(GPIO18, (brd_bits >> 1) & 0x01); // first station to GPIO18
digitalWrite(GPIO22, (brd_bits >> 2) & 0x01); // second station to GPIO22
digitalWrite(GPIO27, (brd_bits >> 3) & 0x01); // third station to GPIO27
// digitalWrite(PIN_SR_LATCH, LOW);
// byte bid, s, sbits;
// Shift out all station bit values
// from the highest bit to the lowest
// for(bid=0;bid<=MAX_EXT_BOARDS;bid++) {
// if (status.enabled)
// sbits = station_bits[MAX_EXT_BOARDS-bid];
// else
// sbits = 0;
// for(s=0;s<8;s++) {
// digitalWrite(PIN_SR_CLOCK, LOW);
// digitalWrite(PIN_SR_DATA, (sbits & ((byte)1<<(7-s))) ? HIGH : LOW );
// digitalWrite(PIN_SR_CLOCK, HIGH);
// }
// }
// digitalWrite(PIN_SR_LATCH, HIGH);
}
But i have a lot of problems…
In first, all the relays of the relay board are partial activated (a low light led but the relay don’t active) before to start Opensprinkler….
After the start, i have the sprinkler 1 and 2 always active and the third intermittent any command on the web interface changes anything…
I think that i make some mistakes….
