Parola Scrolling ESP8266 example

Other Hardware LEDs and Multiplexing

Can I use an Arduino Pro Mini + a ESP-01 ?

Or do I need an all-in-one module?

Also, what is the difference between the Parola_Scrolling_ESP8266 example sketch and the MD_MAX722XX_Message_ESP8266 example sketch ?

One uses the Parola library and the other does not.

As long as it works with the ESP8266WiFi library you can use whatever you like, but I have not tried your hardware combination.

Thanks.

What is the difference?
More sophisticated graphics?

What is an "all-in-one module"?

Combining a Pro Mini with an ESP-01 is a cumbersome business, as you have to arrange level conversion between the 3.3 V ESP-01 and the Pro Mini (unless you use a 3.3 V Pro Mini) and you have to arrange serial communication between the two. Why would you need a Pro Mini? :roll_eyes:

Presuming your intent is to use WiFi, it makes vastly more sense to simply use the ESP-01 to control your scrolling matrix display. That is what I do, though I have not yet actually implemented the WiFi update process. :grinning:

I use the ESP-01 together with its USB support module.

The Parola version would allow you to use any of the animations (with a code change). MD_MAX72xx version is just scrolling.

Which module do you use?

It was a while ago, but from memory it was an early NodeMCU unit.
