Changed timer implementation for 2FSK
Implemented concurrent transmission and packet encoding (not working yet)
Wrote documentation for config.c
Implemented grouped transmission (without preamble)
All dividers for all clocks are static except for HPRE.
HPRE is dynamically changed between /1 and /8. It is usually set to /8.
If the camera is capturing the image, it is set to /1. This is necessary
while the sampling method needs a to sample the fast data from the camera.
After capture, the prescaler is switched back to /8.
HPRE will affect the speed of AHB1 and AHB2. Both have the same speed.
At image capture, both are running at 48Mhz and 6Mhz at all other times.
The clock change has a drastic effect of the power consumption.
--------------------------------------------------
Running at 1.8V
Position packet transmission, APRS AFSK, one packet every 1min (GPS off)
Image transmission, APRS AFSK, one packet every 20sec, redundant TX
=> average consumption 55mW
--------------------------------------------------
Running at 1.8V
Position packet transmission, APRS AFSK, one packet every 1min (GPS off)
=> average consumption 34mW
When a picture was sent, the radio was kept switched on.
The detection of the image EOI did not work for the packet
transmission because the EOI detection returned the method
earlier.
Merged configuration types
Made USB and 3V switch configureable
Removed USB debugging temporarly
Adjusted camera clocking
Removed Si4464 power conversion function
Implemented I2C communication with ublox module
Fixed endless-loop bug in tracking manager
Increased cutoff voltage at which PAC1720 is used
Implemented redundant tansmission option
Moved APRS definitions to APRS related files
Renamed variables (so they get more understandable)
