Tool/software:
Hello,
I am working with a chain of 11 TLC59711 IC's, my issue is when I turn on the pwm for 1 it is turning on the rest of them.
For example setPWM(1,65535) // FULL ON, will turn on 13, 25, etc (Which is the 1 for each chained IC)
Configuration
Arduino UNO SMD

#include <Arduino.h>
#include <Wire.h>
#include "Adafruit_TLC59711.h"
#include <SPI.h>
// How many boards do you have chained?
#define NUM_TLC59711 10
#define DELAY_TIME 2000
#define OFF 65535
#define data 10
#define clock 13
Adafruit_TLC59711 tlc = Adafruit_TLC59711(NUM_TLC59711, clock, data);
struct Command {
int index;
int value;
};
const int MAX_COMMANDS = 121; // Adjust the size as needed
Command commands[MAX_COMMANDS];
int commandCount = 0;
void ledOff() {
for (int i = 0; i < MAX_COMMANDS; i++) {
tlc.setPWM(i, OFF); // Set all channels to 65535 (off)
}
tlc.write(); // Update the TLC to reflect the changes
}
void setup() {
Serial.begin(1200);
//Serial.println("TLC59711 test");
pinMode(10, OUTPUT);
tlc.begin();
ledOff();
}
void ledSlider() {
for (int i = 0; i < commandCount; i++) {
int index = commands[i].index;
int value = commands[i].value;
if (value < 65535) {
tlc.setPWM(index, value); // Full power was 0 this defaults to 0 which is fully on LBJ
} else {
tlc.setPWM(index, OFF); // Turn off
}
}
tlc.write();
commandCount = 0; // Reset command count after processing
}
void readCommands() {
while (Serial.available() > 0 && commandCount < MAX_COMMANDS) {
String command = Serial.readStringUntil('\n'); // Read the entire command line
int commaIndex = command.indexOf(','); // Find the comma separating index and value
if (commaIndex != -1) {
int index = command.substring(0, commaIndex).toInt(); // Extract and convert index
int value = command.substring(commaIndex + 1).toInt(); // Extract and convert value
// Store the command in the array
commands[commandCount].index = index;
commands[commandCount].value = value;
commandCount++;
}
}
}
void loop() {
readCommands();
ledSlider();
