Why in this day and age would you suggest anyone use a 80C32? The more up to date flash based devices are normally faster and less wiring due to the memory being on the chip. Also you don't need an eprom programmer as you can download code with a simple bit of hardware and the PC - much faster to develop code. Also why would you use a timer to do the clock for i2c? and/or SPI for that matter? Much better off bit bashing these interfaces if the device does not support them natively. With most of my apps the timing is all done with one timer. Keep it simple! Shantanu - remember - divide and conquer! Divide your project into small sub-projects and solve the issues on a smaller scale. The problems you perceive with I2C and SPI are most likely non-issues. There is plenty of code to implement these protocols in software (which is the way it's done in many cases). |
