The DiB7000P has 16 bit address size and 16 bit data size. So you need to write 2 bytes where you just using 1. e.g: Start | 0001001 | 0 | Ack | addr_byte_msb | Ack | addr_byte_lsb | Ack | val_byte_msb | Ack | val_byte_lsb | Ack | Stop Why don't you use the driver from LinuxTV and just change the back-end ? regards, Patrick. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
