 		 #86138 - smt160.asm example
Responding to: ???'s previous message
Hello Gopalakrishnan Narayanan,

I was playing with some code to read the period value of a smt160.
You can see it at this address http://members.aol.com/cpu8052/SMT160.ASM.

It uses timer 0 as a 16 bit counter with two more registers to get a 32 bit final value, along with the two external interrupts. The value is read a total of 64 times to get a large sample. The results are feed to an IBM type computer for further processing.

Hopes this helps a little.

Regards,

Charles Bannister
