Hello.

 

Im trying to use this camera with the Netduino 2, I have comunication with it but I have a problem. I send the FBUF_CTRL command well and I have the wright answer,then I send the GET_FBUF_LEN command and I take a good answer too, with a data length around 12K(so thats wright I think). But the problem comes here. When I send the FBUF_READ command I receive the ack well but nothing about the data............what I am doing wrong........in the documentation says thta the data comes by SPI???? I dont think so, becouse I saw that someone has done a library for this camera and it doesnt use the SPI. The thing is that I want generate my own code, so if someone could help me I would be very glad.

Hi again, I have the code running (the one of the post you put before), but instead of saving it in a SD, I pass it to another COM port to send it to a PC. The cuestin is that with the hyperterminal I can see that the data is flowing to the FTDI chip that Im using, but the data doesnt seem to reach the PC...........wich could be the problem???? The baud rates are Wright, bowth of them, the camera and the second uart in 38400  and the serialport in the pc that has to receive data also 38400.

Hello.

 

Finally I have it working.It was a delay problem but I have it solved. So now I have the camera running with my own library and data transfer with a second com port. The next estep is to try to do a face recognition with emgu in the pc. Thank you and i will post how it goes forward.
