Display resetting when using setFont #28
Comments
|
Matrix.begin needs to be set first to initialize the library.
eg
RGB64x32MatrixPanel_I2S_DMA matrix;
...
void setup(){
// If you experience ghosting, you will need to reduce the brightness level, not all RGB Matrix
// Panels are the same - some seem to display ghosting artefacts at lower brightness levels.
// In the setup() function do something like:
matrix.begin(R1, G1, BL1, R2, G2, BL2, CH_A, CH_B, CH_C, CH_D, CH_E, LAT, OE, CLK); // setup the LED matrix
matrix.setFont(&FreeSans9pt7b); // This command causes a reset
matrix.setPanelBrightness(10); // SETS THE BRIGHTNESS HERE. 60 OR LOWER IDEAL.
matrix.setTextColor(matrix.color444(255, 255, 255)); // r,g,b
matrix.setCursor(6, 7);
matrix.print("Leeds 4");
matrix.setTextColor(matrix.color444(255, 0, 0)); // r,g,b
matrix.setCursor(6, 17);
matrix.print("Man Utd 0");
}

Any help very much appreciated

Thanks csloz. @madnat - I've updated the README now to highlight this. |

Thanks! Regrettably the code still aborts with this change :( Again - if I comment out "matrix.setFont(&FreeSans9pt7b); // This command causes a reset" the code runs with default font (6x8) // Test the RGB64x32MatrixPanel_I2S_DMA setFont Function #include <Arduino.h> RGB64x32MatrixPanel_I2S_DMA matrix; //////////////////////////////////////////////////////////////////// // R1 | G1 #define R1 25 void setup(){ matrix.begin(R1, G1, BL1, R2, G2, BL2, CH_A, CH_B, CH_C, CH_D, CH_E, LAT, OE, CLK); // setup the LED matrix matrix.setFont(&FreeSans9pt7b); matrix.setPanelBrightness(50); // SETS THE BRIGHTNESS HERE. 60 OR LOWER IDEAL. } void loop() } |

Apologies. I broke something in the most recent release. Let me debug and report back with fix. |
|
Try again with the latest release 1.2.2 - download from github and try again. THanks |
|
That now works - thanks very much! |
|
Excellent. Closing this issue. |
If I comment out line 43 my project runs... when left as is - the display resets when the print function is called.
What am I missing?
