ARMStamp RXD issue
Posted: Sat Jun 08, 2019 12:01 pm
First off - some of this is unorthodox procedure !!
Attempting to create a Serial Comm link with the ARMstamp - I tested the ability to TXD first. -- Works,but
did notice some "funnies" - a different Forum post.
'
Did not connect the RXD line - (so it is floating?)- but later on did a RXD test and got the "garbage"
as can be seen in the "Debug Variable portion of the picture" - code snippet/function was copied from
one of your forum links re: serial. called 'getline' - [OEM current testing via SPI devices]
'
connected RXD to the Coridium Dongle and I get nothing - not even 'garbage'/CR/LF- from TclTerm which is
connected to the Dongle
'
tested on ARMstamp Production and Beta unit - both fail ::: SuperPro works fine on BAUD(0) & TclTerm & Dongle
'
Could you verify RXD works at 19200 baud on the ARMStamp ???

P.S. a picture is worth ......
