Lacto got a reaction from Fmilburn in OV7670 and MSP430
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?
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

It is not really "better". The chip itself ist better but with the MSP-EXP430F5529LP you get the FET for all SBW-MSPs. You can actually build your own device (with or without boosters) and program more than just the chip on the board.

It's probably because your USCI is not in synchronous mode, add UCSYNC.
In addition, use 3 pin mode since you are not using UCA0STE (UCMODE_1) and SPI mode 1 (UCCKPH)
UCA0CTL0 = UCMSB + UCMST + UCSYNC + UCCKPH; // 4-pin, 8-bit SPI master
