WP34s flash technical erase procedure
I have a question (am confused) about the the erase procedure. Does the erase strobe actually erase anything? It seems to me that the 'flash control sequence' following:
'on' 'hold erase' 'reset' 'on' 'release erase' 'reset' 'on' ... places the 30b in a 'receive' state, ready (as it were) to receive the MySamba send?? Is my understanding correct? comments?? --- also, if we don't actually send, is the firmware for the 30b still there? One more, are the erase and reset pins TTL compatible ? I am thinking about making cross wired nand gates (flip flop) for contact debounce and hold... will the erase | reset work correctly if a standard TTL output from a nand gate strobes the positive signal on erase, or the ground shot on reset? Do you folks think that the positive standard voltage of a TTL inverter will have enough current to power the calculator? ... power the flash? Thanks in advance for the discussion. marcus Kind regards, marcus |
