-#Under construction
\ No newline at end of file
+## Configurations over UART/Serial TTY
+
+To set the below parameters using serial input, use the following:
+
+- To change trigger active duration: `TRG_D` [integer for milliseconds]
+- To change gain factor: `GAIN_F` [integer for gain state - see note*]
+- To change ADC hysteresis value: `HYST` [integer]
+- To change sensor input pullup vRef low threshold: `VFOL` [integer in millivolts]
+- To change comparator trigger high threshold: `VCOMP` [integer in millivolts]
+- To change the duration between ADC measurements: `LOOP_D` [integer in milliseconds]
+
+You can also enable or disable DEBUG output with: `DEBUG` [0|1]
+
+You can query the current configuration with: `CONFIG`
+You can query the current state (including ADC measurements) with: `STATE`
+
+To reset all settings to defaults, use: `RESET`
+
+
+These commands should be wrapped in this format:
+1CMD INT1
+
+Examples:
+
+- `GAIN_F 3` <~ set gain factor to index 3 (6x)
+- `VFOL 2350` <~ set the vref floor to 2.35V
+- `DEBUG 1` <~ Enable debug output
+- `STATE` <~ display current sensor status
+
+*Note for Gain Factor:
+The gain STATE is representative of these values:
+0 = 3x
+1 = 3.5x
+2 = 4.33x
+3 = 6x
+4 = 11x
+
+------------------------
+
+## Calibrating the internal vRef
+
+The adc calculation in this sensor assumes an "ideal" constant value which
+is used to convert the internal 1.1v reference.
+
+Each Atmega chip is slightly different, so it won't be completely accurate
+without tuning. Most of the time this won't be necessary, so don't mess
+with this if you don't know what you're doing!
+
+The reading can be fine-tuned by using a multimeter, and this equation:
+
+```
+scale_constant = internal1.1Ref * 1023 * 1000
+
+where
+
+internal1.1Ref = 1.1 * Vcc1 (per voltmeter) / Vcc2 (per readVcc() function)
+```
+
+If the scale_constant calculated is different from the default 1125300,
+update the voltMeterConstant variable in pP_config.h with the correct value.
+
+## Configuration in firmware
+
+All default configurations are stored in `pP_config.h`.
+
+`#define GAIN_FACTOR_DEFAULT 2`
+ - Gain adjustment factor. 0=3x, 1=3.5x, 2=4.33x, 3=6x, 4=11x
+
+
+`#define FOLLOWER_THRESHOLD_DEFAULT 1450`
+ - Voltage follower default voltage in millivolts (1/1000V)
+
+`#define COMP_THRESHOLD_DEFAULT 2850`
+ - Comparatore Vref default voltage in mV
+
+`#define InitCount 6`
+ - Number of times to blink the LED on start
+
+`#define LOOP_DUR_DEFAULT 50`
+ - Duration of time between ADC checks and other loop functions
+
+`#define TRG_DUR_DEFAULT 20`
+ - Duration of the Z-axis pulse sent, in ms
+
+`#define HYST_DEFAULT 20`
+ - Software hysteresis for ADC/DAC adjustment, in mV (±20 default)
+
+`extern long voltMeterConstant = 1125300L;`
+ - For fine tuning input voltage sense
+
+`extern byte pP_i2c_address = 0xa0;`
+ - I2C Bus Slave Address
