I just came across this well-documented project that connects the MSP430 G-series launchpad with an OV7670 camera module:

It uses the MSP430G2452 and implements:
- I2C to talk to the camera
- 8bit parallel interface to read image from camera
- soft UART to transfer image data to the PC (at 115200 baud)
