Graw DFM-17 radiosonde support (#61) * Initial plumbing for DFM17 (#54) * Implementing Si4063 radio chip support for DFM17 sonde. Work in progress. * Add an error to indicate that the code does not work yet * Removed copyrighted docs from documentation and provided links instead (#55) * Fix SPI bus initialization for DFM17. Trying to make Si4063 SPI communication work (in progress). Fix LED bit polarity. * Set DFM17 clocks correctly to 24 MHz * Still trying to fix Si4063 SPI communication, no luck * Add clearing of SPI overrun status flag to make Si4063 comm work properly in DFM17. Not sure about the reason this is required. * Fix bug when setting Si4063 frequency. Remove unnecessary GPS debug and delays. Add Si4063 debug printout. Find a suitable frequency offset multiplier to achieve 270 Hz tone spacing for Horus 4FSK. * Add some known good Si4063 configuration values. Implement direct GPIO-based modulation for Si4063 that allows support for CW now. * DFM-17 APRS work (#60) * Modify for APRS on DFM17 * Clean up Si4063 APRS work and make APRS deviation configurable * Add documentation for DFM-17 * Add a note about the DFM-17 connector * More work on docs and config for DFM-17 * Docs * Mor work on config * Fix RS41 URL * Added info about high-altitude balloon flights * Fix typo * More code cleanup * Update authors * Improve DFM-17 docs * Added a timepulse routine for DFM17 and also a millis() routine. Working toward clock calibration. * More refinements to the HCI calibration * Cleaned up clock calibration code and integrated into the main radio loop. Also added APRS telemetry for calibration. * Added logic to (hopefully) avoid over-calibration if there is an errant timepulse. * Clean up DFM-17 clock calibration implementation and make RS41 compile properly * Adjust README * Add notes about DFM-17 clock calibration * Fix typo * Add DFM-17 note about clock calibration to the top of the README * Text style * Working on README * Working on README * Move datasheet links to main README * Markdown styling * Improve config file structure * Remove unnecessary comments --------- Co-authored-by: Mike Hojnowski <kd2eat@gmail.com>
