interactive control LimeApiCmd

limeProc items

control limeApiCmd.exe via python uses subprocess , popen

python subprocess

import subprocess
from subprocess import Popen, PIPE
cmd = ['d:\\tools\\LimeApiCmd\\LimeApiCmd.exe']
p = Popen(cmd, text=True, stdin=PIPE, stdout=PIPE, stderr=PIPE)

print(p.poll())			None

p.stdout.readline()
..
.
p.stdout.readline()							'\tfreq    = 1575.419998 MHz  \t   gain = 20 dB\n'
p.stdout.readline()							'cmd_ok\n'

p.stdin.write('getchiptemperature(0)\n')	22
p.stdin.flush()

>>> p.stdout.readline()				'\t32.7333\n'
>>> p.stdout.readline()				'cmd_ok\n'

class LimeProc

interface :

• LimeProc(cmdPath) constructor
• alive() return True/False
• close() return True
• query(cmd,twait) return Tuple (True/False, res0, res1, ...)
• instId return deviceID

example:

"""Tests init lime """
limecmd = ['d:\\tools\\LimeApiCmd\\LimeApiCmd.exe']
lime = LimeProc(limecmd)

print(lime.instId)
print(lime.query('getchiptemperature(0)'))
print(lime.query('getsamplerate(tx,0)'))
lime.close()

output
