#137915 - This is a typical PCA job Responding to: ???'s previous message |
You CAN do it with a 'plain vanilla' derivative and a lot of sweat. Using one of the many derivatives with a PCA will make this a breeze. The PCA was introduced by Intel in the mid 90s and is not a 'rarity' or anything exotic or difficilt. PCA derivatives are available from SILabs, NXP, Atmel, and many more.
How to do it can be found in The PCA cookbook http://www.intel.com/design/mc...270609.htm Should you prefer sweat, then run a timer (prefereably T2) at the samllest interval and use a state machine to control the action. Be careful not to overload the ISR. Erik |
