Is there any reason that a project successful on a 28 pin device (27443) cannot be migrated to an 8 pin device (27143) apart from the obvious pin changes. The original 28 pin device only had 5 pins used for the project.If there are no technical impediments then I must have missed some globals or module configs but I cant see any differences. I will get some feedback before I post the projects for detailed scrutiny and critique. Regards Chris D.
To program the chip in-vito can lead to problems because you connected some hardware to the pins used for programming on the 8-pin device. Programming and then soldering would work better.
The 8-pin device has got no SMP and I'm not quite sure what is with an external X-tal.
According to Cypress you can connect driven outputs to the 1SCL and 1SDA ports as long as the resistance is above 1K (Ithink). The 8 pin seems to program ok. I wonder if I should raise a tech issue?
I will tyr one more thing. I will disconnect the LED connected to the programming port during programming and reconnect for test. I will update the results Chris
