hi every one.

how can i detect a voltage from lead-acid battery using a micro-controller(i'm using sx28ac/dp)? can anybody show me how to connect the controller to the battery? thx very much.
 
U want to monitor the voltage of the bat or just to see if it's below a certain treshhold?
For the second idea u could use the internal comparator. Ul just need a voltage reference and a voltage divider.
About the software...familiar with the PIC's but never used a SX.
FOr the first idea ..use a ADC chip.
 
the idea is to monitor and to control the battery voltage. say, when the bat reaches max level of charging, it will stop charging and if the volt has drop to minimum it will start charging.
 
thanks for the infos guys. but anyway i think i am still going to use the sx for this project. anyone in this forum who has knowledge about the sx is welcome to discuss.
