Arquivo: digipot_mcp4451.cpp Projeto: Mother-Goose/Marlin4Due

// This is for the MCP4451 I2C based digipot
void digipot_i2c_set_current(int channel, float current) {
  current = min( (float) max( current, 0.0f ), DIGIPOT_I2C_MAX_CURRENT);
  // these addresses are specific to Azteeg X3 Pro, can be set to others,
  // In this case first digipot is at address A0=0, A1= 0, second one is at A0=0, A1= 1
  byte addr = 0x2C; // channel 0-3
  if (channel >= 4) {
  	addr = 0x2E; // channel 4-7
  	channel -= 4;
  }

  // Initial setup
  i2c_send(addr, 0x40, 0xff);
  i2c_send(addr, 0xA0, 0xff);

  // Set actual wiper value
  byte addresses[4] = { 0x00, 0x10, 0x60, 0x70 };
  i2c_send(addr, addresses[channel], current_to_wiper(current));
