need help hserin/hserout cmucam4
hi i need help to receive the data as a string then parse it.
im new to programming so please help me..
1. if i enter like HSEROUT ["AG 0",13] the cmucam4 will return either ACK\r or NCK\r
Code:
Dim B1 As Byte
test_ag:
HSerOut ["ag 0",13]
HSerIn [B1]
'if the data received is NCK\r it will repeat test_ag:
'while if its ACK\r it will move to the next part of the code
'or if possible to detect only ACK or NCK without the \r
2. if i enter HSEROUT ["TC",13] it will return
NCK\r
or
ACK\r
T mx my x1 y1 x2 y2 pixels confidence\r
dont know how it would look like
Code:
Dim B2 As Byte
Dim tc_mx As Byte
Dim tc_my As Byte
Dim tc_x1 As Byte
Dim tc_y1 As Byte
Dim tc_x2 As Byte
Dim tc_y2 As Byte
Dim tc_p0 As Byte
Dim tc_c0 As Byte
main:
HSerOut ["TC",13]
HSerIn [B2]
'if the data received is NCK\r it will repeat main:
'while i need to save the values of mx my pixels and confidence.
'mx to tc_mx
'my to tc_my
'pixels to p0
'confidence to c0
'all data recieved are numbers like this:
ACK\r
T 79 59 0 0 159 119 255 255\r
Re: need help hserin/hserout cmucam4
Many different way to skin a cat, but sometime, Hserin timeout feature can be handy.
HSERIN 500, main,[WAIT("ACK\r"), SKIP 1, tc_mx, tc_my,SKIP 4, p0, c0, SKIP 2]
OR something like this will also work
Packet VAR BYTE [11]
tc_mx VAR Packet[1]
tc_my VAR Packet[2]
p0 VAR Packet[7]
c0 VAR Packet[8]
HSERIN 500, main,[WAIT("ACK\r"), STR Packet\11]
may looks like a mess of variable, BUT...
Re: need help hserin/hserout cmucam4
so the code will look like:
Quote:
Dim tc_mx As Byte
Dim tc_my As Byte
Dim tc_x1 As Byte
Dim tc_y1 As Byte
Dim tc_x2 As Byte
Dim tc_y2 As Byte
Dim tc_p0 As Byte
Dim tc_c0 As Byte
main:
HSerOut ["TC",13]
HSerIn 500, main,[WAIT("ACK\r"), SKIP 1, tc_mx, tc_my, tc_x1, tc_y1, tc_x2, tc_y2, tc_p0, tc_c0, SKIP 2]
will it repeat main: if ACK\r doesnt appear?.. like when it recieves NCK\r
and how about #1?
if i enter like HSEROUT ["AG 0",13] the cmucam4 will return either ACK\r or NCK\r
Quote:
Dim B1 As Byte
test_ag:
HSerOut ["ag 0",13]
HSerIn [B1]
'if the data received is NCK\r it will repeat test_ag:
'while if its ACK\r it will move to the next part of the code

How about trying it and see what happen. Those are guideline, really more than enough to begin.
Serial signal sniffer comes handy in those situations.
