Commanding the CMU CAM2 by CM2 controller

2008-07-17T08:24:54+01:00

Hi all,
I tried to send the ascii value of carriage return from the CM2 controller. But i am getting a NCK from the CMUCAM2 . Can anyone help me with this. The piece of code i had written is given below:

typedef unsigned char byte
int main()
{

.......
TxD80(13); //Transmit via serial port

.......
}

void TxD80(byte c)
{
while(!TXD0_READY); // Wait till transmit buffer is empty
TXD0_DATA = c; // put data into transmit buffer
}

Do let me know if there is any error in the implementation.

Thanks in advance.

not too familiar with CM2 but if it were CM5 I would first verify that serial communications is in order. for example write a simple echo program that relays back and forth data between the two serial ports and then connect one to the the PC and the other to the CMUcam2

Hi all,
I am trying to command the CMUcam 2 using the CM2 controller by the TTL serial port of the CMUcam2.

I am not able to figure out the method of sending the command to the CMUcam2. For example: The command SF can be sent from the PC to get a frame from the CMUcam2. But how do I send this from the CM2 controller.

I tried sending the ascii value of S first then the ascii value of F. But I did not get any response.

Can anyone help me out with this.

Thanks in advance
