Ah: maybe that was MOSFETs - not TRIACs.
Anyhow, the same priciples apply: 1. You need to understand the device - what input conditions it requires for operation; 2. You need to understand what output conditions the particular port pin can provide. If these match, then the two can be directly connected - if they don't, then you know what the intervening circuitry needs to do! See: http://www.8052.com/forum/read/160143 |
