Retro Edition
ATTENTION !
Purpose of this SoftRF Edition is NOT for new users! Instead, Prime Mk II Edition is recommended for you to start with.
It has also little sense for current users of ESP- or RPi- based Editions to consider this platform as any kind of an alternative.
- Primary focus of this port of SoftRF firmware onto STM32 platform - is to add support for recent AcSIP's S76G single chip LoRa tracking solution ;
- Secondary purpose of this port - is to retrofit rapidly ageing STM32 OGN tracker's hardware and firmware (it has not been updated for almost a year). This gives a chance for current users of STM32 OGN trackers worldwide to extend service life of this hardware a little bit, then gradually transit onto leading edge SoftRF hardware solutions.
SoftRF/STM32 firmware operation has been validated on STM32F103C8 "Blue Pill" hardware platform.
Pins assignment and wiring was intentionally chosen to match those of that genuine STM32 OGN tracker design has.
