Official Bug Report for LiquidCrystal NKC v0.21.309

Per the LiquidCrystal NKC discussion thread on the official Arduino Forum, a few bugs and issues have been presented in v0.21.309 that I am self-reporting for clarity and accountability, and that I have every intention of resolving by v0.21.316 (Nov. 12th, 2021).

Items with no check marks are issues that have not yet been resolved. Items with check marks are issue that have been resolved and will be included as official fixes in the next weekly release.

MAJOR BUGS

  • Using the I2C_SLOW constant to set the I2C speed to 10kHz breaks functionality. New value suggestion is 50kHz.

OTHER ISSUES

  • The delayMicroseconds(I2CDELAY) line in the I2C command functions is now only after Wire.endTransmission()
  • Some of the delayMicroseconds(RS232DELAY) uses in the RS232 command functions may break functionality.

FORMATTING

LONG-TERM CHANGES

  1. The biggest goal of LiquidCrystal NKC is universal compatibility. Therefore, LC NKC will be made LCD API 1.0 compliant.
  2. The use of init() will be deprecated, yet remain supported. The suggested function going forward will be begin().
  3. The setBacklight() function will be altered to comply with the LCD API 1.0 standard of a non-binary dimming level. To simply set the backlight ON or OFF, use LiquidCrystal compatible backlight() and noBacklight().
  4. Support for more major boards & board-specific pins that auto-update based on the board selected in the IDE.
