6.7.0 Image Processing in Memory

• Upgrade digital CNN to v8.3.0 (added new type of digits)
• Internal update: TFlite (v2.5), esp32cam, startup sequence
• Rollback to espressif v2.1.0, as v3.2.0 shows unstable reboot
• Bugfix: WLan-passwords, reset of hostname

6.6.1 Image Processing in Memory

• NEW 6.6.1: failed SD card initialization indicated by fast blinking LED at startup
• Improved SD-card handling (increase compatibility with more type of cards)

6.6.0 Image Processing in Memory

• Improved SD-card handling (increase compatibility with more type of cards)

6.5.0 Image Processing in Memory

• Upgrade digital CNN to v8.2.0 (added new type of digits)
• Supporting alignment structures in ROI definition
• Bug fixing: definition of hostname in config.ini

6.4.0 Image Processing in Memory

• Additional alignment marks for settings the ROIs (analog and digit)
• Upgrade analog CNN to v7.0.0 (added new type of pointer)

6.3.1 Image Processing in Memor

• Bug-fixing

6.3.0 Image Processing in Memory

• Initial setup mode: bug fixing, error correction
• Bug-fixing

6.2.2 Image Processing in Memory

• NEW 6.2.2: bug fixing
• NEW 6.2.1: Changed brightness and contrast to default if not enabled (resolves to bright images)
• Determination of fixed illumination settings during startup - speed up of 5s in each run
• Update digital CNN to v8.1.1 (additional digital images trained)
• Extended error message in MQTT error message

6.2.0 - Image Processing in Memory

• Determination of fixed illumination settings during startup - speed up of 5s in each run
• Update digital CNN to v8.1.1 (additional digital images trained)
• Extended error message in MQTT error message
• Image brightness is now adjustable
• Bug fixing: minor topics

6.1.0 - Image Processing in Memory

• Disabling of analog / digital counters in configuration

• Improved Alignment Algorithm (AlignmentAlgo = Default, Accurate , Fast)

• Analog counters: ExtendedResolution (last digit is extended by sub comma value of CNN)

• config.ini: additional parameter hostname (additional to wlan.ini)

• Switching of GPIO12/13 via http-interface: /GPIO?GPIO=12&Status=high/low

• Bug fixing: html configuration page, wlan password ("=" now possible)

• Major change: image processing fully in memory - no need of SD card buffer anymore
  Need to limit camera resolution to VGA (due to memory limits)

• MQTT: Last Will Testament (LWT) implemented: "connection lost" in case of connection lost to TopicError

• Disabled CheckDigitIncreaseConsistency in default configuration - must now be explicit enabled if needed

• Update digital CNN to v7.2.1 (additional digital images trained)

• Setting of arbitrary time server in config.ini

• Option for fixed IP-, DNS-Settings in wlan.ini

• Increased stability (internal image and camera handling)

• Bug fixing: edit digits, handling PreValue, html-bugs
