I have friends at big EDA cos using cracled software all time. They just dont use the software at work. They dnot seem to be worried.

shanren,
Cygn@l has 8051s with SPI, although the price is a weak point. Use software to simulate SPI is not so difficult (some C51 may have library).

I would suggest you use an OSD chip (philips, nec). Those ICs can be controlled via serial connections (I2c) by the MCU you pick. Then you need the timing signals. If you have a video source, use a sync strip IC (Elantec) to get the timing signals. Other wise use a PLL chip and an OSC to...

Here is the i2c_write function using bit bang.
void i2c_write (unsigned char output_data)
{
unsigned char index;
for(index = 0; index < 8; index++) // Send 8 bits to the I2C Bus
{
// Output the data bit to the I2C Bus
SDATA = ((output_data & 0x80) ? 1 ...

PCF8574 is an I2c port expander. You need the I2c driver for whatever system (CPU or OS) you are using.
There are lot of sample I2c C codes from IC makers (P*hli*ps, A*tm*el etc).
Hope it helps
