Holas Martin, este componente lo encontré en este post
Anteriormente en la versión FC8, se instalaba el componente en la carpeta de COMPONENTES, y este aparecía en el listado, pero ahora en la versión de FC10 lo instalo en la carpeta y no lo puedo ver en el listado de componentes
¿Como puedo hacer, para que el macro aparezca en el listado?
Hello Martin, I found this component in this post “Martin Fisher great component Max7219_v2 a question Solved”
Previously in the FC8 version, the component was installed in the COMPONENTS folder, and it appeared in the list, but now in the FC10 version I install it in the folder and I can't see it in the components list
How can I do so that the macro appears in the list? Ready to use it
Thanks / Gracias

Can you post the code you tried? I only looked at one MCU - but the 18f252 should have plenty of RAM. What issue are you getting. Won't compile, or it doesn't work on hardware?

Are you setting the pins in properties (including CS)

This should run through some demo routines...
I used the 18f252 but should work with others if they sufficient RAM - it uses 8 bytes for each of 16 displays (max allowed as far as I remember)
Note also that it doesn't do anything in simulation.
