Hm. Hat jemand eine bessere Idee? Speicher: Wie schließt man am Besten ein externes paralleles 32kB RAM am PIC an? Die Doku beschreibt, daß ein Port des PIC18 als Datenport konzipiert ist. Wie aber soll die Adressgestaltung aussehen? Schließlich brauche ich noch einige I/O für das allgemeine Handling

Blutrausch wegen i2c
das Hardware-TWI die gewünschten 100kHz I2C-Takt bei nur 1Mhz Prozessortakt nicht schafft (beim Mega32). Datenblatt lesen (und ein externer Quarz) hat mir dann weitergeholfen. Oliver
in og. Quelle stehts so drinn... Der Aufruf in der init [C] // set i2c bit rate to 100KHz i2cSetBitrate(100); [/C] und die Funktion dazu [C] void i2cSetBitrate(u16 bitrateKHz) { u08 bitrate_div; // set i2c bitrate // SCL freq = F_CPU/(16+2*TWBR)) #ifdef
