Is there a maximum storage time for Picaxe micros? In January 2008, I bought ten 08Ms. Since then I have successfully programmed and reprogrammed five of them a number of times. The other five have never been touched; they were still pushed into the black conductive foam they arrived in. They have been stored in a drawer in a normal living room, no extremes of temperature or humidity.
Today I tried to program one of the last five units. A standard message was displayed that said the programmer was not plugged in, not switched on, etc. I used one of the first five devices and no problems; there was nothing wrong with the program I was loading or the hardware to program it.
I then tested all five of the previously unused devices with the same result.
The first five devices are fine but the last five are not recognized.
The programmer is the Pickaxe experimenters board for 08, 18 and 28 pin devices, the cable is a Picaxe USB to serial cable and the power supply is a 12vdc wall wart supplying the boards built-in 5v regulator.
