1, I connect a SPI host(Aardvark_I2C_SPI_Host_Adapter) to M40 by SPI.
and try SPI communication.
the connection:
OM0 to high, OM1…OM3 to low.
2, after power on, the IRQ output will drop from 3.3V to 0V.
after send any one of the below commands, the IRQ will jump to 3.3V.
i send the same command many times, the data with yellow color don’t change.
3, the reading data is something wrong. I just want to read the network type.
the M40 model is AB6704 M40 ETHERNET IP MODULE.
please help to tell me where is wrong. if the command is wrong, or procedure is wrong?
