Stack-based programming

A project log for DYPLED

a thin LED display in SIP module format, much better than TIL311s to visualise your computer buses

No I won't talk about FORTH ;-)

Today I received a pair of little adapter boards for TSOP-48. The cheaper chinese adapters are "wide" and I prefer the narrow ones that match the DIP48 format because it's more compact. I'll use this assembly to prototype the whole DYPLED board, on a prototype-style drilled board so I need something to flash the chip a few times while I code and verify the contents of the Flash array.

As soon as I got the boards, I soldered one AM29LV160DB. The pins are soldered in the opposite side because this particular chip has a reversed pinout (see other episodes such as Flash EEPROM adventures (and a happy end)...). I have another board for the other chip reference that should arrive soon, with a standard pinout and 5V tolerance :-)

Why did I choose this title for the log ? Because when I need to program the module, it makes a weird stack of adapters :-D
