Sven Steudte 1cea4b1573 Finalized clockling (so far) for power savings. 
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

Sven Steudte 20b70a5680 Adjusted clocks for low power operation (camera fix no implemented yet) 2017-08-30 05:29:59 +02:00
Sven Steudte 23c42f83c3 Fixed faulty image transmission, implemented server exception handling in decoder 2017-08-29 00:35:16 +02:00
Sven Steudte 934fd1ec3a Adjusted clocks 
Flipped image in OV5640 driver
Fixed spelling
 2017-08-28 04:14:56 +02:00
Sven Steudte 70ff480b43 Fixed radio kept swiched on 
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.
