2.3.1.6
Header J3 is provided for in-system circuit programming using either ICD 2 or
PICkit
2.3.1.7
Header J5 is provided for serial data logging using the PICkit
source code for the evaluation board contains the code necessary to transmit data via
a PICkit
data currently logged consists of charging current setpoint, output voltage, temperature
thermistor voltage, current system state, and termination code.
The data logging feature allows the user to create and save a complete charging profile
for a specific battery pack. The interface software provided with the PICkit Serial
Analyzer allows the user to save the logged data to a file.
- Qualification: Precharge at 200 mA for V
