| // CTC-DRA-13-1 ISOLATED DMX-RDM SHIELD JUMPER INSTRUCTIONS | |
| // | |
| // If you are using the above mentioned shield you should | |
| // place the RXEN jumper towards pin number 2, this allows the | |
| // master controller to put to iso shield into transmit | |
| // (DMX Master) mode | |
| // | |
| // | |
| // The !EN Jumper should be either placed in the G (GROUND) | |
| // position to enable the shield circuitry | |
| // OR | |
| // if one of the pins is selected the selected pin should be | |
| // set to OUTPUT mode and set to LOGIC LOW in order for the | |
| // shield to work | |
| // | |
| // | |
| // The master will control 100 Channels (1-100) | |
| // | |
| // depending on the ammount of memory you have free you can choose | |
| // to enlarge or schrink the ammount of channels (minimum is 1) | |
| // | |
| #define DMX_MASTER_CHANNELS 100 | |
| // | |
| // Pin number to change read or write mode on the shield | |
| // | |
| #define RXEN_PIN 2 | |
| // Configure a DMX master controller, the master controller | |
| // will use the RXEN_PIN to control its write operation | |
| // on the bus | |
| DMX_Master dmx_master ( DMX_MASTER_CHANNELS, RXEN_PIN ); | |
