ACC Keyboard for Open Interface III

UNDER DEVELOPMENT

This keyboard plug in Open interface III with IP switch realize low latency (<4ms with ethernet switch) IP control 16 output relays in two bank. BankA switch each each independet output on/off. BankB switch always one output from eight available. BankA is upper line switch buttons, BankB bottom line.

Firmware

BankA and BankB (ACC keyboard)

Keyboard functionality enable in Open Intrface III firmware with enable below variables to 1

boolean ACC_KEYBOARD    = 1;          // Shift in/out register via ACC
boolean KeyboardAnswLed = 1;          // Keyboard Led shown answered UDP packet from IP RemoteSwitch

Also must be installed and configured ethernet module

boolean ETHERNET_MODULE = 1; // enable ETHERNET module (must be installed)

and IP Switch with ESP32-GATEWAY in local network with DHCP

boolean RemoteSwitch    = 1;          // IP controled remote RemoteSwitch

devices are pair in network automaticaly.

How ID are use on actual selected band, determines table in firmware

// BAND TO REMOTE SWITCH ID
int BandToRemoteSwitchID[12] = { /*
IP Switch
  ID
 0-7  */
  0,  // band 0 (no data)
  0,  // Band #1 [160m]
  0,  // Band #2  [80m]
  0,  // Band #3  [40m]
  0,  // Band #4  [30m]
  0,  // Band #5  [20m]
  0,  // Band #6  [17m]
  0,  // Band #7  [15m]
  0,  // Band #8  [12m]
  0,  // Band #9  [10m]
  0,  // Band #10  [6m]
  0,  // Band #11  [2m]
};

By default using on all bands IP switch with ID 0.

BankC - rotary encoder

Open Interface III use for IP switching from rotary encoder (BankC) independents hardware. ID calculate automaticaly increase eight from ID for ACC keyboard. This means that in previous situation on all bands rotary encoder (menu 20) use IP switch with ID 8. Range rotary encoder is up to 16 outputs, wich may be limited for each band separately in table

int IpSwBankCrange[8]= { /*
number of IP switch bank C position
 2-16 range */
  16, // ID 8
  8,  // ID 9
  8,  // ID A
  8,  // ID B
  8,  // ID C
  8,  // ID D
  8,  // ID E
  15,  // ID F
