APPENDIX A: THE SKETCHBOOK CONTENTS
4. ADC conversion settings can also be modified in the
Setup Variables section. The default setup is to run the
ADC in Normal mode, which has a 7kHz filter code; in this
mode the ADC_OPT bit is disabled. Typical choice for which
cell to convert is ALL. Full ADC conversion programming
requires setting ADC_OPT, ADC_CONVERSION_MODE,
CELL_CH_TO_CONVERT, AUX_CH_TO_CONVERT,
and STAT_CH_TO_CONVERT. These variables are pro-
grammed with constants listed in the LTC68xy_daisy.h
file. For simplicity they are also listed below.
MD_422HZ_1KHZ
MD_27KHZ_14KHZ
MD_7KHZ_3KHZ
MD_26HZ_2KHZ
ADC_OPT_ENABLED
ADC_OPT_DISABLED
CELL_CH_ALL
CELL_CH_1and7
CELL_CH_2and8
CELL_CH_3and9
CELL_CH_4and10
CELL_CH_5and11
CELL_CH_6and12

To set the ADC to have a 1kHz filter corner the ADC_OPT
and ADC_CONVERSION_MODE variables would be
changed as follows.
ADC_OPT = ADC_OPT_ENABLED;
ADC_CONVERSION_MODE = MD_422HZ_1KHZ;
To convert only cells 2 and 8,
CELL_CH_TO_CONVERT = CELL_CH_2and8;
5. In another example, the user may wish to change the
undervoltage and overvoltage thresholds. Each number
is based on an LSB of 100µV.
//Under Voltage and Over Voltage Thresholds
const uint16_t OV_THRESHOLD = 41000;
// Over voltage threshold ADC Code.
// LSB = 0.0001
const uint16_t UV_THRESHOLD = 30000;
// Under voltage threshold ADC Code.
// LSB = 0.0001
