[fpc-pascal] How to use UART of ARM platforms (e.g. Raspberry Pi ) through free Pascal?

2013-07-03 Thread Dennis Poon 

Anyone has some sample codes or links to share on this?

So far, I only found this:  
http://code.google.com/p/fprpbm/source/browse/#svn%2Ftrunk%2Fexamples%2Fminiuart%253Fstate%253Dclosed


Thanks in advance.

Michael,
I used the synapser.pas unit but the compiler choked at line 232 at the 
identifier 'B50', 'B576000'  not found.

Any idea ?

Dennis

After some studying, synaser.pas seems to deal with com port instead of 
the low level UART interface.
Can you give me some pointer on directly using UART? I need to implement 
half-duplex using UART for rs-485 protocol.


Thanks.

Dennis
