15.01.2017 Enable/Disable and set data rate of the PIco RS232 is now working. Fixed default to
disabled RS232. Fixed data rate programmable by user written to PIco EEPROM. Usage
is described in the manual in a proper section.

15.01.2017 Changed Battery Powering Backup activation threshold from
4.75V
on 5V GPIOs to
4.65V
Remark:
Now the UPS PIco HV3.0 is checking the following conditions for Battery
Power Backup activation on the following conditions:
1. Continuously Fast Falling Powering Edge Monitoring (proprietary algorithm)
2. GPIO 5V powering is unconditionally lower than 4.65V
This will help when used lower quality PSUs that are giving higher voltage drop than
should be when system is loaded.
In any case we
strongly recommend
using PSU with micro USB cable on the same body
with the PSU, and minimum, recommend
3A.

informing user about It. This option was temporary (in former version of
firmware - 0x18) disabled to rewrite firmware part procedures from floating point
arithmetic to fixed one, in order to decrease memory footprint and system speed-up.
