B4R Question Problem with rLedControl

[Eme Fibonacci]

I'm trying to use this library with Arduino:

https://www.b4x.com/android/forum/threads/spi-i2c.66420/#post-420609

The setChar method does not show the char properly. Only one column is shown.

Any idea?

Thank you.

The library code looks correct. Does SetDigit work properly?

No, but

led.SetLed 'Ok
led.SetColumn 'Ok
led.SetRow 'Ok

You need to test the native library with Arduino IDE and see whether it works properly or not. There is an example here: https://github.com/wayoda/LedControl/tree/master/examples/LCDemo7Segment

Does not work.

In arduino page: "LedControl a Arduino library for the MAX7221 and MAX7219" Works very well.

Sorry. I'm wrong. This library should be used for an matrix 5x8 my matrix is 8x8. I will write a code 100% B4R.
