BCD or GRAY code to feed or spindle override

Hello,

Is there any hal component or source code to convert a bcd or gray code (4 input bits) to a float or unsigned integer output ?

I have a BCD (and a gray) rotary switch and i want to use it in the front panel to control the feed and speed override (connected to halui).
The conversion is not linear, is based on these tables:
Feed override table (4 bits): 1%, 2%, 5%, 10%, 20%, 40%, 50%, 60%, 80%, 90%, 95%, 100%, 105%, 110%, 120%. 130%
Speed override table: 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100%, 105%, 110%, 115%, 120%, 125%

Other solutions are welcome

Thanks you in advance,
VNR

The counter works great ! Thanks you .

But now i have a new problem.

Touchy do not follow halui.feed-override.value at all. This value is always 0, but the screen shows 100%. I want to use touchy because i have a touch screen monitor.

I tried with Axis, always starts with 100%, don't matter what the rotary encoder position is.
I have to move the switch one position and then Axis starts to follows halui.feed-override.value.

--- HAL FILE ---

loadusr -Wn arduino python arduino.py

loadrt mux16 names=sp_ov,f_ov

setp halui.feed-override.count-enable TRUE
setp halui.feed-override.direct-value TRUE
net feed-ov-connect f_ov.out-s => halui.feed-override.counts
#La escala en 1 es 100%
setp halui.feed-override.scale 0.01

--- HALTCL (with Axis) ---

haltcl: show pin halui.feed-override
Component Pins:
Owner Type Dir Value Name
7 bit IN TRUE halui.feed-override.count-enable
7 s32 IN 105 halui.feed-override.counts <== feed-ov-connect
7 bit IN FALSE halui.feed-override.decrease
7 bit IN TRUE halui.feed-override.direct-value
7 bit IN FALSE halui.feed-override.increase
7 float IN 0.01 halui.feed-override.scale
7 float OUT 1.05 halui.feed-override.value

I have to move the switch one position and then Axis starts to follows halui.feed-override.value.
setp halui.feed-override.count-enable TRUE
What happens with count-enable FALSE?

Procedure:
1) Start Axis with: setp halui.feed-override.count-enable FALSE in hal file
2) move the switch and halui.feed-override.value follows the switch, but Axis doesn't change (always 100% in screen)
3) haltcl: setp halui.feed-override.count-enable TRUE
5) Axis doesn't change to the current halui.feed-override.value value
6) Move the switch and Axis now follows the halui.feed-override.value value

My own thinking is that Axis waits for an initial change in halui.feed-override.value to actualize the initial value of 100%. May be was writen with an incremental encoder in mind not an a absolute encoder.


In the other hand, I put in touchy.hal : net feed-ov-connect => touchy.wheel-counts
Touchy is working but not correctly, something is not working between Touchy and Halui:

haltcl: show pin halui.feed
Component Pins:
Owner Type Dir Value Name
7 bit IN TRUE halui.feed-override.count-enable
7 s32 IN 50 halui.feed-override.counts <== feed-ov-counts
7 bit IN FALSE halui.feed-override.decrease
7 bit IN TRUE halui.feed-override.direct-value
7 bit IN FALSE halui.feed-override.increase
7 float IN 0.01 halui.feed-override.scale
7 float OUT 1.12 halui.feed-override.value
HALUI is Wrong, Touchy also shows in screen 112%

7 s32 IN 100 halui.feed-override.counts <== feed-ov-counts
7 float IN 0.01 halui.feed-override.scale
7 float OUT 1.25 halui.feed-override.value
HALUI is Wrong, Touchy also shows in screen 125%

7 s32 IN 110 halui.feed-override.counts <== feed-ov-counts
7 float IN 0.01 halui.feed-override.scale
7 float OUT 1.1 halui.feed-override.value
HALUI is OK, but Touchy shows in screen 127%

A workaround might be to connect up the BCD bit signals in the posgui HAL file instead. Axis is already up and running at that point, so should see the value change.

Doesn't work.

I will try to modify the touchy code to support this rotary encoders, it only support incremental encoders and don't read the halui parameter halui.feed-override.value.

Thanks you for your help !
