Marco,
Thanks again for your reply and I fully agree that using Zones would be the best way forward and I intend to adopt the Parola Library and the zones technique in future projects as I can see it would be a lot more versatile.
Unfortunately at this point it would take a lot of Hardware and wiring changes, to re-arrange everything into One big String of Matracies with one connection to the Arduino.
For this project which now has very tight time constraints, I have simplified the design somewhat and added a separate set of 4 MAX7219 Modules, as a separate display for the secret code that is to be displayed when the game is solved.
I have made a lot of progress with the project now that I am not trying to rotate any of the text or use the same displays for the secret code as I am using for the Bar-graphs.
The only issue i have now, as you can see from the attached photographs is that when the game is solved, I can't seem to change the text on the Code Display (Lines 103 and 104) from "? ? ? ?" to the secret code "6 C 3 A".
I borrowed some code from your MD_MAX72xx_Print_Text Example, hope that was O.K. and configured the MD_MAX72xx Instances as follows.
// Define the number of devices we have in the strips and Code display and the hardware interface
#define HARDWARE_TYPE MD_MAX72XX::FC16_HW
#define MAX_DEVICES_BARGRAPHS 16
#define MAX_DEVICES_CODE 4
#define CLK_PIN 13 // or SCK
#define DATA_PIN 11 // or MOSI
#define CS_PIN 10 // or SS1
#define CS_PIN1 9 // or SS2
#define CS_PIN2 8 // or SS3
#define CS_PIN3 7 // or SS4
// SPI hardware interface
MD_MAX72XX mx0 = MD_MAX72XX(HARDWARE_TYPE, CS_PIN, MAX_DEVICES_BARGRAPHS); //Bargraph 1
MD_MAX72XX mx1 = MD_MAX72XX(HARDWARE_TYPE, CS_PIN1, MAX_DEVICES_BARGRAPHS); //Bargraph 2
MD_MAX72XX mx2 = MD_MAX72XX(HARDWARE_TYPE, CS_PIN2, MAX_DEVICES_BARGRAPHS); //Bargraph 3
MD_MAX72XX mx3 = MD_MAX72XX(HARDWARE_TYPE, CS_PIN3, MAX_DEVICES_CODE); // Used For Secret Code
MD_MAX72XX mx[] = {mx0, mx1, mx2, mx3};
I am using the code below
/**
Called when the puzzle is solved
*/void onSolve() {
#ifdef DEBUG
Serial.println("Puzzle has just been solved!");
#endif
//Set the Background Neopixle LEDS to Solid Green as Puzzle Has Been Solved
// use a loop to fill all Background Neopixel LEDS GREEN
for (int i = 0; i < numLedsBack; i++) {
// Set the i'th led to green
backleds[i] = CRGB(0, 255, 0);
FastLED.show();
message[BUF_SIZE] = "6 C 3 A";
printText(0, MAX_DEVICES_CODE - 1, message);
puzzleState = Solved;
}
}
to change the message but it doesn't seem to overwrite the original message "? ? ? ?" which is initially set in the void setup() section of the sketch.
I tried using
char message[BUF_SIZE] = "6 C 3 A
printText(0, MAX_DEVICES_CODE - 1, message);"
but this just screws ALL of the displays up ?
When the puzzle becomes un-solved the Code Display should return to "! ! ! !"
/**
Called when the puzzle (which previously had been solved) becomes unsolved
*/
void onUnsolve() {
#ifdef DEBUG
Serial.println("Puzzle has just become unsolved!");
#endif
//Set the Background Neopixle LEDS to Solid Red as Puzzle Has Been Un-Solved
for (int i = 0; i < numLedsBack; i++) {
// Set the i'th led to red
backleds[i] = CRGB(255, 0, 0);
// Show the leds
FastLED.show();
}
message[BUF_SIZE] = "! ! ! !";
printText(0, 4 - 1, message);
puzzleState = Running;
}
I have attached the full code in the hope you can point me in the right direction to why the "new message" isn't being sent to the Code display.
Regards,
Fimez.
