| | 3 | If you are installing parallel port adapters it means you are probably messing |
|---|
| | 4 | around with wires and IC's and the like. If you have purchased a card that |
|---|
| | 5 | provides an external i2c/smbus this will require combined algorithm and |
|---|
| | 6 | adapter code in a single module. |
|---|
| | 7 | If you are doing it yourself by using the parallel port there |
|---|
| | 8 | are basically 2 options. |
|---|
| | 9 | |
|---|
| | 10 | 1) Using the parallel port and using the i2c-pport adapter module and the |
|---|
| | 11 | i2c-algo-bit algorithm module together to enable you to wire up your parallel |
|---|
| | 12 | port to act as an i2c/smbus. This provides a bus that will enable most |
|---|
| | 13 | sensors to work but doesn't support the entire i2c/smbus capability. |
|---|
| | 14 | |
|---|
| | 15 | 2) Using the parallel port to interface to a Philips PCF8584 parallel to i2c |
|---|
| | 16 | adapter chip. You will need to build a bit of a circuit to do this. This |
|---|
| | 17 | configuration needs the i2c-pcf-epp adapter module and the i2c-algo-pcf |
|---|
| | 18 | algorithm module. This support almost all of the i2c/smbus capabilities. |
