DSP:

  • 4 ADC channels (8 kHz Fs/4 safe frequency)
  • FFT staged calcuation (8x stages)
  • FFT dB fast log10f

Rx:

  • ADC op-amp gain?
  • op amp Vcc?

Tx:

  • do IQ Tx work this way?
  • how to form CW signal
  • CW bell-shape (LUT?)

GFX:

  • generic progress bar (vol, agc, dsp load, etc.)
  • correct FFT display
  • volume slider
  • icons (volume, etc.)
  • clearing part of display instead of whole buffer

UI:

  • Encoder via interrupt + speed test
  • ADC buttons
  • menu system
  • category menu system (names, function pointers...)
  • splashcreen
  • splash RLE

Misc:

  • auto reset circuit (one reset for everything)
  • EEPROM emulation
  • MCP23S17 driver + check
  • SSD1309 SPI DMA driver
  • CD4066 ADC audio switch
  • RTC
  • INA219 i2c
  • Battery indication
