Accurately calculate RF frequency value (#9)

Frequency deviation/receiver bandwidth (#8) ...

- 10/20 kHz is enough to remove temperature susceptibility
- fix display of negative temperature values

Resolve suspectibility to temperature changes ...

- increase transmitter frequency deviation to 40 kHz
- increase receiver bandwidth to 80 kHz
- (almost) fix display of negative temperature values

Better sprintf

Set frequency deviation accurately to 40 kHz

Update README.md

Resolve suspectibility to temperature changes (#7) ...

- increase transmitter frequency deviation to 40 kHz
- increase receiver bandwidth to 80 kHz
- (almost) fix display of negative temperature values

Accept and display failed CRC, sync word tolerance (#6)

Update README.md

Update README.md

Fix output power setting, set frequency deviation (#5)

Update README.md

Read and display RSSI value (#4)

Set Fading Margin Improvement as recommended in datasheet

Allow to pass bg and fg color for monochrome bitmaps and fonts (#3)

Update README.md

Just some cleanup (#2)

Temp. "log", Unifont, LNA 50 Ohm + high sensitivity

Some cleanup, simplify, comments

Minor changes ...

- RC calibration is done automatically at power-up
- set RSSI threshold to recommended default

Do not block CPU while waiting to receive temp. reading (#1)

Don't clear whole screen between temperature updates
