REFERENCE INFORMATION

LBP16

ELBPCOM

ELBPCOM is a very simple demo program in Python (2.x) to allow simple checking

of LBP16 host communication to the 7I92. ELBPCOM accepts hexadecimal LBP16

commands and data and returns hexadecimal results. Note that the timeout value will need

to be increased to about 2 seconds to try flash sector erase commands.

import socket

s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM,0)

sip = "192.168.1.121"

sport = 27181

s.settimeout(.2)

while(2 >0):

sdata = raw_input ('>')

sdata = sdata.decode('hex')

s.sendto(sdata,(sip,sport))

try:

data,addr = s.recvfrom(1280)

print ('>'),data.encode('hex')

except socket.timeout:

print ('No answer')

Sample run:

>01420001 ; read hostmot2 cookie at 0x100

> fecaaa55 ; 7I92 returns 0x55AACAFE

>82492000 ; read EEPROM IP address at 0x0020

> 450a5863 ; 63:58:0A:45 = 99.88.10.69

;(for example)

>01D91A00025A82C920000100a8C0 ; write EEPROM IP address

;(at 0x0020) with

; C0:A8:0:1 = 192.168.0.1
