TS-7180 FPGA
From embeddedTS Manuals
The TS-7180 FPGA registers are accessed over I2C. The supplied 'tshwctl' utility may be used to access these registers; run 'tshwctl -h' to see how to use it.
The FPGA is available at I2C addresses 0x28-0x2f. First write the address which is 16-bits, followed by the data which is 8-bits.
The tables below list all the registers and their functions.
Address | Bits | Description |
---|---|---|
0-43 | 7:3 | Reserved (Write 0) |
2 | GPIOn Input Data | |
1 | GPIOn Output Data | |
0 | GPIOn Output Enable | |
307 | 0 | BT/MODEM# control[1] |
308 | 0 | HD1/GPS# control[2] |
309 | 0 | PWM control[3] |
