Hi MMBasic friends,

I recently bought an AS5600 rotary magnetic encoder.
Very pleased with it, easy to use (see my code)

As a man who's fitted an accelerometer to the catflap,
I'm always looking for like-minded souls.
( haha!.. think I've found a few in this shed ! )

Can we think of a good application for this module,
maybe a weathervane, or an inverted pendulum..

'---------------------------------------------
' AS5600 magnetic rotary encoder DPJ
' 3v3 4096 steps/360 deg
' agc ideally returning about 64
'---------------------------------------------

addr=&h36 'I2C address
Dim agc,rah,ral,ang As integer
'ie auto gain control, angle high byte,low byte,result angle
Pause 50 'power-up delay
I2C open 100,100,PU 'set up I2C..
'this is speed kHz,timeout ms, pullup

rdlp:

Pause 100
I2C write addr,0,1,&h1A 'select agc reg
I2C read addr,0,1,agc
I2C write addr,0,1,&h0C 'select raw ang reg
I2C read addr,0,1,rah
I2C read addr,0,1,ral
ang=(rah<<8)+ral
Print ang;" ";agc;" ";Chr$(13);

GoTo rdlp

Try swapping 2 and 3 over

You just gotta love someone with such dedication!

Neat device

For multi-turn, the MCU would need to keep track though, right?
