Peťan: To je divný, mezi jednotlivými fonty není nějaký rozdíl v řízení. Prostě se jenom posune offset a z „tabulky“ to načítá jiné hodnoty. Není spíš špatný LED panel, že by svítily nějaké LEDky, které u jiných fontů nesvítí?

if (adr == 2 && systemState == 0 && (showMode == 1 || showMode == 2) && !showText) {
//date and temperature point
//if (i == 5) lc.setLed(adr, 5, 7, true);
//if (i == 6) lc.setLed(adr, 6, 7, true);
if (i == 7) lc.setLed(adr, 7, 7, true);
}
}

I guess the last thing that bothers me as a graphic designer is colon on tempertaure
it currently looks like this

I wanted to move it a point lower – and almost I even managed to do it, but the colons flashed and were almost invisible.

I’m still thinking about how to turn off the front zero within e.g. 01:21 or 09.00 °C
but I haven’t come up with anything yet, I wanted to set it as a condition somehow, but I have no ideas for now and I’m not that knowledgeable about code

BTW – I made 3 symbols

Peťan: You can change code in row 1058 (similar in row 1068 for date and 1080 for temperature) to this -> „if(hour > 9){DrawSymbol(3, (hour / 10) + (font * 10) + fontOffset – 10);}else{DrawSymbol(3, 0);}„. First zero will hide. If you agree I’m going to add your symbol to code on GitHub.

I analyzed the code a bit, but I can’t create a function only for 1 display , e.g. DrawSymbol2,
which will allow me to display only for 1 display a font moved one column to the right or left.

this is my font version „left of display“

Peťan: Hi, you can just add both fonts to the program – for example font#1 (left aligned) and font#2 (centered). Then in row 1163 change red-highlighted text to „(font + 1) * 10“ – see pic. https://www.mylms.cz/wp-content/uploads/2023/10/comment-9409.png That symbol will draw by font#2. Other symbols will draw by font#1

What are the reasons of these issues and how to overcome?

Peťan: Hi, I did not have this kind of issue. Maybe you have bad stability of dc power source… You can try add more time (change 10 to 1000) in line 410 – here https://github.com/mylms/Arduino-Matrix-Clock/blob/1.5/ArduinoMatrixClock/ArduinoMatrixClock.ino#L410

Po zadani ? pres seriovou komunikaci se mi nevypisuji nstavene parametry. Ostatni yadavani parametru funguje. Nevite, kde je problem?

Corrected but not working,

Tried this but not work for me. Double check and correct me if there are any mistake. Here is image of my pasted code. https://freeimage.host/i/sCJhEg

Peťan: You have mistake on line 147. You should write „byte second, minute, hour, dayOfWeek, dayOfMonth, month, year, lastMinute; //global variables for time„.
