// PinOutput represents a pin hardware abstraction layer for a pin that can output a digital signal.
|
|
// This is an alternative to drivers.PinOutput abstraction which is a function type. Pros and cons
|
|
// of both approaches have been discussed in the [relevant issue]. PinOutput should only be used
|
|
// to expose an initialization function of a driver that receives pins of this type. Ideally
|
|
// driver developers should also expose the initialization with drivers.Pin type:
|
|
//
|
|
// func New(p1, p2, p3 legacy.PinOutput) *Device {
|
|
// return NewWithPinfuncs(p1.Set, p2.Set, p3.Set)
|
|
// }
|
|
//
|
|
// func NewWithPinfuncs(p1, p2, p3 drivers.PinOutput) *Device {
|
|
// return &Device{p1:p1, p2:p2, p3:p3}
|
