Länge, Leitungskapazität! (siehe meine Mail 'Re: Schaltung die fünfte') Ich würde zumindest einen PCA9517 zwischen internen und externen I²C-Bus schalten. Heinz
als vollwertigen SPI nutzen. Heinz K. schrieb im Beitrag #3819495: > Ich würde zumindest einen PCA9517 zwischen internen und externen I²C-Bus > schalten. Extern?...... habe ich 4x max485. Wegen der Leitungskapazität muss ich leider abstriche machen. Leider habe ich auf der Strecke nur 5x1,5

plus I C-bus devices in additional to SMBus. The TCA9406 is not a bus buffer like the PCA9515A and PCA9517. It provides both level translation and physically isolates the capacitance to either side of the bus when both sides are connected. The I offfeature can be utilized to isolate the bus into high impedance

drive levels, P82B715 is compatible with bus buffers that use voltage level offsets, e.g., PCA9511A, PCA9517, Sx/Sy side of P82B96. The lower V OL level and ability to operate with any master, slave or bus buffer is the primary advantage of the using the P82B715 for long distance buses at the disadvantage
