V1.9.12 - Updates

• Fix southern hemisphere returning incorrect DEC values

V1.9.11 - Updates

• Add focuser command support to LX200 protocol.

V1.9.10 - Updates

• Fixed a bug that caused a compilation fail when enabling LCD_BUTTON_TEST
• Allowed connection test to be set in local config

V1.9.09 - Updates

• Sample Local Config - disabled as default

V1.9.08 - Updates

• Continuous integration improvements. Checking for version and changelog changes automatically

V1.9.07 - Updates

• ALT and AZ steppers can now be enabled and configured seperately.
• Reduced hold current for AZ and ALT to 10% if using TMCs and NEMAs.
• Fixed incorrect response in Meade LX200 guide pulse command.

V1.9.05 - Updates

• Lowered connection baudrate to 19200.
• Fixed incorrect response in Meade LX200 quit command.

V1.9.03 - Updates

• Removed connection test check and made it standard.
• Switched motors to normal mode (better perf), but allowed silent mode through XX_UART_STEALTH_MODE defines.
• Made DEC driver be in Guide microstep mode unless slewing.
• Added command to Meade protocol to calculate stepper positions for stellar coordinates.
• Fixed an overflow bug in the CAL LCD menu for RA/DEC steps (esoteric mounts).

V1.9.00 - Updates

• Fixes RMS current setting for TMC2209 UART to be more accurate and consistent
• Disables i_scale_analog (aka "USE_VREF") by default so that results are more consistent between users. rms_current will no longer depend on Vref, unless specifically configured by the user.
• Changes UART baud rate to 19200 rather than the default of 115200 - the Rx channel was too unreliable and repeatedly had CRC errors at the higher baud rate.
• Adds a test method for visual confirmation of Tx-only UART connectivity. At boot (before tracking starts), each axis will rotate slightly in each direction driven purely by UART commands. If the user sees the movement, they know UART Tx is functioning.
• Re-enabled support for different microstepping settings for slewing and tracking.
• Allowed microstep settings to be defined in the local config.
• Seperated guide stepper from DEC stepper so that guiding doesn't change DEC coordinates.
• Fixed a bug where tracking speed was not calculated correctly, nor adjusted on the fly when RA Steps/deg were changed.
• Saved some RAM by moving strings to flash memory.
• Fixed a bug where RA would jump a little at the beginning of a GoTo operation.
• Added Meade command to allow querying driver settings.
