    Can Usart mode be used with the I2C mode in the 16F PICs?

    Hi I am interested in using two buses in my design: one I2C and the other Usart. I know that the SPI can't be used in parallel with the I2C- Its obvious as it uses the same pins... but what about Usart? The pics in question are the 16f876a. Thanks in advance.

    Looking for a QFN/QFP/BGA to DIL or Breadboard Adapter.

    Looking for a QFN/QFP/BGA to DIL or Breadboard Adapter.

    qfn adapter Hi I was looking around for a QFN/QFP/BGA to DIL Adapter but I can't find anything that would be cheap enough for a hobbyst but would still be reusable. I found a couple Clamshell ones but they usually costed 200$(sic!) the chip itself was 10$... Anybody knows of online shops...
