history:
V2.2 18.08.20 code is now compatible with standard OLED displays
and original code base (default pw length = 32)
V2.1 18.07.20 added support for ESP8266 based Wifi Kit 8
(by Pulsar07/ (https://heltec.org/project/wifi-kit-8/)
R.Stransky is a ESP8266 with
* a build in OLED 128x32
* battery connector with charging management
* reset and GPIO0 button
R.Stransky is a ESP8266 with
a build in OLED 128x32
battery connector with charging management
reset and GPIO0 button
support for a tare button (PIN_TARE_BUTTON)
bug fixed: wifi password now with up to 64 chars
bug fixed: wifi data (ssid/passwd) with special
bug fixed: wifi data (ssid/passwd) with special
character (e.g. +) is now supported
for specified battery type, voltage is displayed
for specified battery type, voltage is displayed
using uncompressed html files makes WEB GUI much faster
V2.0 26.01.20 Webpage rewritten, no bootstrap framework needed
add translation to webpage (en, de)
optimized for measuring with landinggears
updated to ArduinoJson V6
firmware update over web interface
V1.2.1 31.03.19 small bug fixed
V1.2.1 31.03.19 small bug fixed
values in model database are rounded
mDNS and OTA did not work in AP mode
V1.2 23.02.19 Add OTA (over the air update)
