Hej guys (and gilrs also in case there are any), I am trying to connect a OV7670 (no FIFO) to a MSP430G2553 (3.3 V, 28 pins). As the OV7670 is only tolerant up to 2.8 V I use a MSP430G2231 at 2.8 V and ~11 MHz to feed the XCLK of the OV7670. Everything else should be handled by the 2553 (3.3 V). The 2231 works fine and I am listening to the output pins of the OV7670 with the 2553. The problem: there is nothing. Any ideas? http://www.ebay.de/itm/VGA-OV7670-CMOS-Camera-Module-Lens-CMOS-640X480-SCCB-W-I2C-Interface-Arduin-M35-/301724381213?hash=item46402cb01d:g:UPoAAOSwcu5UNjqp Reset is at 0V 3V3 is at 3.3 V GND is at 0 V The I2C pins have pull up resistors to 2.8 V
I just came across this well-documented project that connects the MSP430 G-series launchpad with an OV7670 camera module: http://www.rpg.fi/desaster/blog/2012/10/20/ov7670-fifo-msp430-launchpad 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)
