An Arduino library for MAX7219 and MAX7221 Led display drivers
I've added just a single pixel turn on method, it's not a beautiful code but it works at least for me.
Hello Wayoda Thanks for the great job. Ledcontrol library is incredibly useful (and I do love LED displays). Is the library still maintened ? I notice that interesting commits didn't...
I am an inking. I was lucky to learn Aduino, but I failed to find the file. I downloaded all versions but failed. I want to know why. I downloaded...
When I power up the device, Led matrix 32x8 shows undesired artifacts. Can't find a way to suppress this behavior.
In my project (imer for my enlarger) I use a MAX7219 controled through the LedControl library. In the sketch setup I have the follwing Lines: lc.shutdown(0,false); lc.setIntensity(0,10); lc.clearDisplay(0); DspLeft(Char_E, Char_Bl,...
Hi, I have changed just 2 rows of the LedControl.cpp so that the library can use the SPI protocol. I added 1. #include <SPI.h> as the first row, 2. SPI.transfer(spidata[i-1]);...
I would like to "daisychain" 10 7219 chips using ledcontrol.h but I am only successful with 8. Is this a software issue or a chip issue? Thanks
I was thinking about using a 5x5 led matrix and the LEDControl library for one of my projects. I need it to scroll text, and I need it to display...
For unknown reasons the library converts uppercase 'C' to lowercase 'c' if you use setChar. You may want to use uppercase one, most likely for temperature display but not only...
getDeviceCount() gets the highest adress not amount of devices.
