Cl-K8055

About cl-k8055d

Interface for the Velleman K8055 USB kit through the K8055 linux driver. The driver library is included for x86-64 and ARM.

How To

Connect to the board/s.

(k8055:connect)

Read out or set some values to the inputs/outputs.

;; Inputs
(k8055:digital 0)
(k8055:analog 0)
(k8055:analogf 0)
(k8055:analogv 0)
;; Outputs
(setf (k8055:digital 1) T)
(setf (k8055:analog 0) 120)
(setf (k8055:analogf 0) 0.25)
(setf (k8055:analogv 0) 5.0)
;; Counters
(k8055:counter 0)
(k8055:reset-counter 0)

If the voltage mapping that is provided by default (4.7V for outputs, 10V for inputs) is not correct, you can adjust it with the voltage accessor.

Once you're done, you should probably disconnect again.

(k8055:disconnect)

accessor (

`ANALOG`

CHANNEL)

Accessor to the analog inputs and outputs.

The values should be integers, which will be truncated to
the range [0,255].
The channel must be an integer in [1,2].

accessor (

CHANNEL)

Accessor to the analog inputs and outputs.

The values should be voltage floats, truncated to the
respective input/output voltages.

See VOLTAGE
See ANALOGF

accessor (
