David Fletcher / Mbed 2 deprecated cc3100_Test_websock_Camera_CM4F

Port of TI's CC3100 Websock camera demo. Using FreeRTOS, mbedTLS, also parts of Arducam for cams ov5642 and 0v2640. Can also use MT9D111. Work in progress. Be warned some parts maybe a bit flacky. This is for Seeed Arch max only, for an M3, see the demo for CM3 using the 0v5642 aducam mini.

Dependencies:   mbed
