COMMUNICATION PROTOCOL E8-V5 - SIC-Venim s.r.o.

•E6_TO_PC Code 'S' (0x53 in hexadecimal)
Data
Answer
= Name[0x0B] reserved[0x01] Kind[0x01]
= Name[0x0B] reserved[0x01] Kind[0x01] [File contents(n bytes)]
Name : file Name to look for, or 12 NULL char for every file
File name must be 12 bytes long, padding with NULL char to the right
File name must be in upper-case without space (char 0x20).
reserved : one reserved byte, must be NULL
Kind : 0 = all kinds 2 = marking file
4 = dot logo file 5 = scribbling logo file
File contents : all the bytes of the file
Example :
String to send :
[0x02][0x00][0x35][0x53][0x00][0x0D]
a b c d
e
[0x54][0x45][0x53][0x54][0x00][0x00][0x00][0x00][0x00][0x00][0x00][0x00][0x02][0x03]
f
g h i
Answer string:
- When the TEST file has been found
[0x02][0x00][0x35][0x53][0x02][0x22]
a b c d
e
[0x54][0x45][0x53][0x54][0x00][0x00][0x00][0x00][0x00][0x00][0x00][0x00][0x02][File contents(533)][0x03]
f g h j i
- When there is not TEST file
[0x02][0x00][0x35][0x53][0x00][0x00][0x01][0x03]
a b c d
e
a = Start of Text [STX]
c = Protocol version
e = Data size
g = reserved
i = End of text [ETX]
k = Error : file not found
b = Desable check-sum
d = Command code
f = File name
h = File kind
j = File contents
