Linux/Arm Newbie Lost in IO Land:
I am trying to both read and write to pin 4 of DIO1 Header and have no
success.
The schematic shows it only going to ADC0 of EP9301 [Sheet 1 of 4] but
the TS7200 Manual Says other wise. Does Pin 4 go to PortC bit0? If so
how do I use it for reading? I had no success configuring direction
for read and reading using the peekpoke routine?
The Pin 4 of the DIO1 Header, in the default configuration, is
accessed via bit 0 of Port C
in the EP9302. The address location 0x8084_0008 is Port C Data
Register and
0x8084_0018 is Port C Directon Register.
Table: DIO1 Header Pin Configuration
DIO1 Pin Default Signal TS-7200
1 DIO_0
2 GND
3 DIO_1
4 Port_C0 ADC0
