hi,
I want to control daisy chained polkadot51s. Can any one suggest me to write the code for it ?
The following code can control one polkadot51
int datapin = 10; // DI
int latchpin = 11; // LI
int enablepin = 12; // EI
int clockpin = 13; // CI
unsigned long SB_CommandPacket;
int SB_CommandMode;
int SB_BlueCommand;
int SB_RedCommand;
int SB_GreenCommand;
void setup() {
pinMode(datapin, OUTPUT);
pinMode(latchpin, OUTPUT);
pinMode(enablepin, OUTPUT);
pinMode(clockpin, OUTPUT);
digitalWrite(latchpin, LOW);
digitalWrite(enablepin, LOW);
}
void SB_SendPacket() {
SB_CommandPacket = SB_CommandMode & B11;
SB_CommandPacket = (SB_CommandPacket << 10) | (SB_BlueCommand & 1023);
SB_CommandPacket = (SB_CommandPacket << 10) | (SB_RedCommand & 1023);
SB_CommandPacket = (SB_CommandPacket << 10) | (SB_GreenCommand & 1023);
shiftOut(datapin, clockpin, MSBFIRST, SB_CommandPacket >> 24);
shiftOut(datapin, clockpin, MSBFIRST, SB_CommandPacket >> 16);
shiftOut(datapin, clockpin, MSBFIRST, SB_CommandPacket >> 8);
shiftOut(datapin, clockpin, MSBFIRST, SB_CommandPacket);
delay(1); // adjustment may be necessary depending on chain length
digitalWrite(latchpin,HIGH); // latch data into registers
delay(1); // adjustment may be necessary depending on chain length
digitalWrite(latchpin,LOW);
}
void loop() {
SB_CommandMode = B01; // Write to current control registers
SB_RedCommand = 127; // Full current
SB_GreenCommand = 127; // Full current
SB_BlueCommand = 127; // Full current
SB_SendPacket();
SB_CommandMode = B00; // Write to PWM control registers
SB_RedCommand = 1023; // Maximum red
SB_GreenCommand = 0; // Minimum green
SB_BlueCommand = 0; // Minimum blue
SB_SendPacket();
delay(250);
SB_CommandMode = B00; // Write to PWM control registers
SB_RedCommand = 0; // Minimum red
SB_GreenCommand = 1023; // Maximum green
SB_BlueCommand = 0; // Minimum blue
SB_SendPacket();
delay(250);
SB_CommandMode = B00; // Write to PWM control registers
SB_RedCommand = 0; // Minimum red
SB_GreenCommand = 0; // Minimum green
SB_BlueCommand = 1023; // Maximum blue
SB_SendPacket();
delay(250);
}
