TODO: excitation voltage range, settling time cycles

[mjmeli]

These need to be implemented. Anyone is welcome to contribute.

Excitation voltage range: Table 10 (pg. 23)

Settling time cycles: Table 13 (pg. 25)

Shouldn't it be a simple matter of the following:

` #define CTRL_VOLT_RANGE1 (0b00000000) #define CTRL_VOLT_RANGE2 (0b00000110) #define CTRL_VOLT_RANGE3 (0b00000100) #define CTRL_VOLT_RANGE4 (0b00000010)

/**

• Set the excitation voltage range.

• @param range The voltage range

• @return Success or failure */ bool AD5933::setExcitationVoltageRange(unsigned int range){ byte val; if (!getByte(CTRL_REG1, &val)) return false;

  // Clear out bits D9 and D10, which are the excitation voltage range bits val &= 0xF9;

  switch(range){ case 1: val |= CTRL_VOLT_RANGE1; break; case 2: val |= CTRL_VOLT_RANGE2; break; case 3: val |= CTRL_VOLT_RANGE3; break; case 4: val |= CTRL_VOLT_RANGE4; break; default: return false; } return sendByte(CTRL_REG1,val); }`

Probably, this wasn't used in our implementation that used this library and so it was simply never written. If you have written this and it works then feel free to do a PR.

Great, I'll be sure to do so when I am able to test it with hardware.

Thanks for posting this by the way, saved me some time!

has anyone built all the code involving CN-0217 and all the ranges. kindly attach code as it would be very helpful.I have made the hardware but finding difficulties in code. Thanks qaisar
