10.03.2017
Corrected (and activated) option for the first A/D converter pre-scaled to 5.2V at
0x69
and address
0x16
. This option was temporary disabled to change firmware from
floating point arithmetic to fixed one, to decrease memory footprint and system speed
up. Higher Voltage
could be
supplied to this A/D converter when added an extra
resistor and set a proper variable in the PICo interface. Readings are in 10
th
of mV in
BCD format. Usage is described in the manual in a proper section.
The High Voltage
Conversion interface is not activated yet.

12.03.2017
Added option for the all 3 A/D converters a Raw Data Readings, with internal Reference
to 2.048V (always with Internal Resistors divider presented on a dedicated manual
part). Each reading is passed from the “Olympic Score filtering” as also software Low
Pass Filter. There are not rounded as also not converted to voltage. Just raw data. In
order to ready the user, need to write the
0xFF
to the
setA_D register
.

Improved the Dynamic Power Tracking and separated currents for micro USB and
External Powering with different current thresholds. The EPR has higher current 800
mAh

15.03.2017
Activated automatic FAN controls, set as default option, temperature thresholds are:
35 Celsius for ON and 34 Celsius for OFF (1 Celsius hysteresis). User can change the
threshold; however, the hysteresis will be always 1 Celsius. Default the FAN speed is
set to 50%, user can change it. FAN is NOT working when system is in Low Powering
Mode

18.03.2017
Added LED OFF, which switches OFF all software, controlled LEDs. CHG, FAN, EXT
cannot be switched off as are connected to the hardware and controlled by it. By
writing the 0x00 to LEDOFF disable the LEDs. Default is 0x01 (means LED ON)
0x31

10.04.2017
Corrected bug (generated in the 0x30) with RS232 deactivation. Now the if the RS232
is deactivated for PIco (and free for Raspberry Pi Applications) the TXD and RXD pins
are HiZ and not High Level like before.
