| Erm...hrm.
This was a little embarassing actually. Now it works! 
But a question still: the fuses - how are they to be used? How many fuses are there and what is the purpose of them? |

| Erm - I might add that I'm not totally new to this. I have done a few projects on the 16f84. It's just that I have never before experienced that nothing happens at all.

Forum: General CCS C Discussion Posted: Thu Apr 29, 2004 5:46 am Subject: Is it possible to have two 16F84A communicating through i2c? |
| I am doing a project where I get a value from a A/D converter (pcf8591) into my 16F84. Those values are supposed to be sent to another 16F84, preferrably on the i2c-bus.
Is this possible? It seems ... |
