doc Schmatics of the si5351 breakout board added. 2016-09-22 10:07:39 +02:00
firmware firmware: Analog read was to shaky, the number of read per millisecond is now increased to 20. meas.py: Some modifications to get the output more userfriendly. CSV output is implemented now. 2016-09-21 20:02:58 +02:00

This project is reengineered out of the TenaTester build by ZL1CVD.
The firmware is completely written by myself, the wheatstone bridge was mostly drawn as seen in the TenaTesta demo videos by ZL1CVD on youtube. The electrical component values were modified by myself to fit my personal requirements. The si5351 prt in the schematics was replaced by an adafruit breakout board.
