I think secret labs should get a camera to try in order to see whats going on

let us know how you get on

i just find it strange that the command that fails is when im trying to get the image data out of the camera. Functions that work are.

reset

set image size

set baud rate

set compression

take a pic

get image size

stop pic

this code does not work with np2. I'm using a different lib and im having issues too. I had to go back to the NP1

my post

Is there is an issue here somewhere! the NP2 does not like this camera when trying to get the data out of the camera after its been setup

we know. it says so in the specs

I can do basic IO on this chip without any issues but can i get the interrupt to work, no. Been at it for a few days and im not making any progress, please help!!!!

Hardware setup:

NP2+, clk & data lines have pull up resistors, 2 leds on the output of the mcp chip. 2 simple switch for the input with pull up resistors which is shorted to ground when switched. INTA on the mcp has a direct connection to the NP2+ to DIO0.

private void SetupPort(Port port){byte IODIA = IODIRA;byte IOCONAddress = IOCON;byte GPINTENAddress = GPINTENA;byte INTCONAddress = INTCONA;byte INTCAPAddress = INTCAPA;byte DEFVALAddress = DEFVALA;if (port == Port.PortB){IODIA = IODIRB;GPINTENAddress = GPINTENB;INTCONAddress = INTCONB;INTCAPAddress = INTCAPB;DEFVALAddress = DEFVALB;}// I/O expander configuration 1010 0000this.device.Write(new byte[] { IOCONAddress, 0xA0 });// Interrupt on change pin 00001111 first 4 are enabled only cus they are inputsthis.device.Write(new byte[] { GPINTENAddress, 0x0F });// default value to compare before the interrupt hitsthis.device.Write(new byte[] { DEFVALAddress, 0x0F });// Interrupt on change control reg, interrupts on default valuethis.device.Write(new byte[] { INTCONAddress, 0x0F });// clear the interupt capture regbyte[] ReadBuffer = new byte[] { INTCAPAddress };this.device.Read(ReadBuffer);// Direction register 11110000 first 4 are outputs and the rest are inputsthis.device.Write(new byte[] { IODIA, 0xF0 });// set outputs to 0//SetIOPort(port, 0);}

basicaly the setup is the first 4 bits to be inputs (interrupt driven) and the next 4 bits as outputs.

ive configured to only go high when it receives a high level from the input.

Its not working at all.

netmf-toolbox does not do interrupts.

Changed everything to adapt to your code and still nothing.

Thanks for help but ive implemented a software interrupt routine now.

hi, tried your code and it does not work for me

will be relaying the data on as the NP2 has no imaging libs so we cant process the image internally (which would of been great).

So its not looking like anyone has played with high speed image capturing then

Has anyone got any experience capturing images at high speed?

The current camera we are using can take an image heavily compressed @ 320 x 240 and transfer the image in about over a second via a TTL serial interface.

I need a camera at a resolution of at least 640 x 320 and the transfer rate of well under a second. Any help would be very much appreciated
