Just to be sure...the camera is really TTL level and not RS-232 right?
And you do know for certain that it is sending something to the mote?
I interpret your "comunicate via RS-232 (MIB-510) using minicom" to
mean that comm between the mote and the host over over the serial
line works fine. Are you sure the camera is working correctly and
doesn't require some request protocol that you are not following?

Hi all,
I'm trying to connect a CMUCam2 with a MicaZ via Uart. Since the camera
can't understand TOSMsg packets i need to change commands byte-to-byte.
A attached a TTL Serial port into MicaZ expansion Uart pins (27 and 28).
The comunication uses Micaz default settings 57.6 Kb, 8 bits no parity,
1 bit stop word.
In MicaZ programming side I'm using the HPLUART interface... the send da
function works pretty fine but teh get one (to receive data from the
camera don't work). When a comunicate via RS-232 (MIB-510) using minicom
teh comunication works perfectly.
Can anyone point me some direction???? A have tried a lot of things and
nothing worked. He is a sample of my code:
module TestUartCamM {
provides {
interface StdControl;
}
uses {
interface Leds;
interface Timer;
interface HPLUART;
}
}
implementation {
// uint8_t cnt;
uint16_t cnt;
char * msg = "l0 1\r";
task void sendChar() {
atomic {
if(cnt < strlen(msg)) {
call HPLUART.put(msg[cnt]);
}
}
}
command result_t StdControl.init() {
// para começar do incio do texto
atomic {
cnt = 0;
turn = 0;
}
call HPLUART.init();
return SUCCESS;
}
command result_t StdControl.start() {
call Timer.start(TIMER_ONE_SHOT, 5000);
return SUCCESS;
}
command result_t StdControl.stop() {
call Timer.stop();
return SUCCESS;
}
event result_t Timer.fired() {
post sendChar();
call Leds.redToggle();
atomic {
turn++;
}
return SUCCESS;
}
event async result_t HPLUART.get(uint8_t data) {
call Leds.greenOn();
if(data == 'A' || data == 'a') {
call Leds.greenOn();
}
else {
call Leds.greenOn();
}
return SUCCESS;
}
event async result_t HPLUART.putDone() {
atomic {
cnt++;
}
post sendChar();
call Leds.yellowToggle();
return SUCCESS;
}
}
