camera lib for nrf52 dk

[SJY]

Does any one have any library connect the nrf52 DK to a camera with GPIO?

Many thanks

Care to tell us what sort of camera you are talking about.

You know you can get UART based cameras

Video or still camera?

What do you mean by, "connect to a camera" - simply to control it? Or to get pictures/video from it?

[SJY]

What I mean is that I want to connect the camera with GPIO, and get pictures in 15fps. Transfer the data through the GPIO. Also, there is one external flash connect the processor with GPIO as well. Finally, the picture will transfer to the external memory.

I know we have some code ported to the nRF52 for the Arducam mini 2MP which uses SPI (data) and I2C (control) to communicate with the camera. If this is what you look for I will ask if we can make it public.

UPDATE:

Here is an example for PCA10040 or PCA10056 for ArduCAM mini 2MP:

ArduCAM.zip

cpplib.zip

The example do not use the standard SDK drivers, but custom ones written in C++. The cpplib folder have to be placed under nRF5_SDK_13.0.0-1.alpha\components. The ArduCAM folder should be placed under nRF5_SDK_13.0.0-1.alpha\examples\MyProjects or similar folder.

See the ArduCAM::spiTwiInit() function for which pins are used for the ArduCAM mini 2MP. If the VCC and GND pin on the ArduCAM are bent, the module can be directly connected in header P4: P0.22-P0.27 on PCA10040 (nRF52 DK), and P24: P1.09 - P0.13 on PCA10056 (nRF52840 PDK).

Yes please. I am really appreciate it. Could I have access to the lib?
