I recently acquired a BS2PX24 to replace and upgrade a BS2P24 which had let all the magic smoke out. I got it when Parallax was selling all the BS2 variants at a significant price reduction recently. It had worked fine when it arrived, ran several programs on it to make sure it was ok. I shelved it for a while since I was deeply involved with a Propeller project. Last week I decided to update some of my BS2P programs for the BS2PX, powered it up in the same board I used when it first arrived. I found that the 'PX would properly identify when I used the IDENTIFY icon on the Editor toolbar. It responded with :
COM15 Basic Stamp 2px24 V1.1 Yes Yes
When I try to load a program the same Identify screen comes up blank followed with a "No Basic Stamp Found" message.
I am using a Prolific USB to Serial adapter which worked on this Stamp before. Also tried a FTDI adapter and get the same result. Both work fine on a BS2. I tried reducing latency under port settings without any change. Also tried setting Port 15 baud rate to 19200 with same result. The Editor is version 2.5.3.
Windows 7 reports that both adapters have the latest drivers installed.
The board is powered by a fully charged 9.6 Volt NiCd battery pack. Voltage to the Stamp is 4.97 Volts.
I am beginning to think that possibly my new BS2PX, now past it's warranty, has put all 24 of it's furry little feet up in the air.
Does anyone have any ideas?
