Mixing-and-Matching hardware platforms¶
In MPF it’s possible to mix-and-match your hardware platforms. For example, you could use a P-ROC for your coils and switches while using a FadeCandy for your LEDs. (Or, if you wanted to be crazy, you could use a FAST controller for your switches and a P-ROC for your coils and lamps.)
You can specify hardware platforms in three ways:
1. Machine-wide default platform¶
Whatever you set in the
hardware: platform: section of your machine-wide
config is the default platform for all types of mechanisms across all of MPF.
hardware: platform: p_roc driverboards: pdb
In the above config, the P-ROC platform will be the default for everything. (switches, coils, lights, LEDs, DMDs, servos, etc.)
2. Device-specific default platform¶
If you want to specify a default for a certain class of devices that is
different than the machine-wide default, you can also do that in the
hardware: section by adding an entry for the type of device you want to
specify the default for.
For example, if you want to use a P-ROC as the default for everything except for LEDs, which you want to be FadeCandy, you would do it like this:
hardware: platform: p_roc driverboards: pdb leds: fadecandy
You can enter a device-specific default for the following types of devices here:
3. Overriding the platform of individual devices¶
Finally, you can override the platform of an individual device by adding a
platform: setting to that device.
For example, if you’re using a FAST Pinball controller which can control up to 256 LEDs, but you also want to add some more LEDs that will be attached to a FadeCandy, you could set up your config like this:
hardware: platform: fast leds: led00: number: 0-0 led01: number: 0 platform: fadecandy
In this example, led00 will use the FAST platform (and the number 0-0 is a FAST configuration number), and led01 will use the FadeCandy platform (and the number 0 is a Fadecandy number).
You could also invert this, like so:
hardware: platform: fast leds: fadecandy leds: led00: number: 0-0 platform: fast led01: number: 0
In the example above, led00 is still a FAST LED and led01 is still a FadeCandy LED, but the difference is that while the default platform is FAST, the default platform for LEDs is FadeCandy. That means you don’t have to specify the platform for LEDs attached to the FadeCandy, but you do need to specify the platform for LEDs attached to the FAST controller.
