ESP32is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. TheESP32series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations and includes in-built antenna switches, RF balun, power amplifier,...
For the fractional part we use Newton's Divided Difference method for polynomial interpolation between the integer parts. Long story short this method has an accuracy of 0.01% and runs in 0.2 microseconds. If you just use the integer lookup method the error is greater than 10% and takes 0.1...
Stored color pallets ( interpolation happens in SRAM ) Arduino buffers ( 64 byte reserved for Serial buffers, I2C buffers, SPI buffers if they are initialised ) other things stored in SRAM ( Serial.print("some text "); uses SRAM to store the "some text" ) ...
