'[PIC]: Serial comms Simulator'
John De Villiers
Im in the process of trying to code a plugin for misim DE that does serial
( Receive ) comms. Transmit will come later, have to get my head around java
Anyways, I can never remeber the polarity issue.
When i use a pic ( 16f84 ) to talk rs232 via a max232 or similar level
translator, does my "1" bit have to be ttl high or ttl low ? I know the
serial line uses high for 0 and low for 1 and idle is 0 ( high line states )
and start is 1 ( low line state )
Also, besides actually catching the transmitted bytes and displaying them
what other "features" should i add to the plugin?
I was thinking of :
1) Checking the pluse lenghts to check for possible overruns
2) Baud rate to be wholy user settable, even allowing rates that a PC cannot
3) Parity checking
4) Option to look for 9-bit addresses
5) Option to select transmission via max 232 type or "direct drive"
6) Any Speed Processor
Any ideas / comments ?
