hallo herr feucht, hier erst mal meine mail adresse mit der ich in der piclist drin bin, adresse: tobias stra=DFen am roderkamp 27 54298 igel (wie das tier) :-) des is 10km von der luxembourgischen = grenze weg tel. 06501 945257 diese nummer hab ich wenn ich nicht @home bin aufs celly umgeleitet so = dass die eigentlich uninteressant ist.(ich weiss sie gar nicht auswendig) meine fh email adresse ist strasset@fh-trier.de der posteingang is net so stark in gebrauch also besser dort hin mails = packen, da die dann eher ins auge stechen. vielen dank f=FCr unser telefonat und ihre zeit, ich bestell mir bei mchip = nun direkt mal pic24er prozessoren vielleicht gibts ja welche die man = noch so verl=F6ten kann Peter Feucht schrieb: > Hi, Rich, > > I'm using a flash memory type 25PE80 from ST which has 16MBit =3D 2 Mbyte. > It's rather slow, not slow in reading and writing, but as usual with flash > it needs to be erased before re-writing and erasing the whole memory needs > about 30 seconds!!!
