RE: Alternative WP34S flashing using Arduino
The point is, emece67, that Arduino can easily be already available on the desk or in the drawer of a lot of people: it can be quite convenient.
I agree with you that purposely get an Arduino for this would be quite fool, given the alternatives we have. And... yes, a well documented method is surely a big advantage and help to the many that would like to transform their 20-30b. Not everyone is an electronic wizard and besides the mythical HP cable and the, unfortunately too, now unavailable Harald's boards, the "average wannabe" user's only chance is to wander in the forum trying to imagine how to connect wires, erase etc.... So, ok, I'll get one of the simple USB-TTL interfaces and will try to put notes and photos to share. (by the way: someone there who used Arduino at 5V TTL levels is around? Ok: the RX from Arduino can easily be dropped to 3V with two resistors 4k7 -10k to ground. But TX at Arduino side still is 5V while HP sends 3V: just put a 1k?!?) Fabio |
