Re: Noob question: examine arbitrary memory address? #ELF #memory


John,  Check the RX pin at the 1802, does it get a pulse?  What character are you sending for Autobaud?  This might matter?  Read the monitor documentation.  I know capital 'U' is one of my favorites because it produces a nice 010101010 pattern for scoping.  Is the 1802 program actually running?  Scope the address lines, you should be able to see the address lines match the baud rate loop.  Keep turning stones!

Cheers, Josh

If the loop back works, proving the physically connections are working, but nothing is ever sent to the TX pin (as measured on the ‘scope), does that imply the monitor software is still in the loop trying to calculate the baud rate?
