How to map 360 degree angle over 1024 counts

[breadcat248]

I am interfacing an absolute encoder to a RPi following this guides:

https://github.com/HareshMiriyala/Absolu...encoder.py

The counts from 0-1023 are able to be shown but i am stuck at how to map out the angles to the counts. I tried using int function to divide but keep on getting errors. Any advice would be greatly.

import time import RPi.GPIO as GPIO   GPIO.setmode(GPIO.BCM)   PIN_CLK = 2 PIN_DAT = [3,14] PIN_CS  = 4 delay = 0.0000005 ns = 1 # number of sensors attached # totally 10 bits to be extracted from SSI signal bitcount = 16   # pin setup done here try:     GPIO.setup(PIN_CLK,GPIO.OUT)     GPIO.setup(PIN_DAT[:],GPIO.IN)     GPIO.setup(PIN_CS,GPIO.OUT)                                                                                                        GPIO.output(PIN_CS,1)     GPIO.output(PIN_CLK,1) except:     print "ERROR. Unable to setup the configuration requested"                                       #wait some time to start time.sleep(0.5)   print "GPIO configuration enabled"   def clockup():     GPIO.output(PIN_CLK,1) def clockdown():     GPIO.output(PIN_CLK,0) def MSB():     # Most Significant Bit     clockdown()   def readpos():     GPIO.output(PIN_CS,0)     time.sleep(delay*2)     MSB()     data = [0]*ns           for i in range(0,bitcount):         if i<10:             #print i             clockup()             for j in range(0,ns):                 data[j]<<=1                  data[j]|=GPIO.input(PIN_DAT[j])             clockdown()         else:             for k in range(0,6):                 clockup()                 clockdown()     GPIO.output(PIN_CS,1)     return data   try:     while(1):         print readpos()         time.sleep(0.001)         #break           finally:     print "cleaning up GPIO"     GPIO.cleanup()

I didn't work with raspberry pi and embedded
python, but I suspect that PIN_DAT = [3,14] should be PIN_DAT = [3.14], if 3,14 stands for pi here...?!

1 2 3 4 5 6

def deg2count(angle, maxcount=1023):     """ 0 <= angle <= 360 """     return int(angle / 360.0 * maxcount)   def count2deg(count, maxcount=1023):     return int(count / maxcount * 360)

Since your code includes series of numbers 3,1,4 (pi approx 3.14), I suspect that
angles should be given in radians; in this case my code should be changed, e.g. 360 must be replaced with, e.g. 3.1415 * 2.

Thanks for the suggestion. Imma try out it and get back to you. Have a nice day.

Hi, i managed to solve the issue albeit with a different code.
Line 60 changed to:
print ([x*0.3519 for x in readpos()])

Nonetheless, i greatly appreciate your attention and advice!
