add one byte to another, with one byte result

Add two numbers, and calculate the modulo of the sum and a third number, M. In other words, it returns (A+B) % M. It is designed as a compact mechanis

Calculate an integer average of two unsigned 16-bit integer values (uint16_t). Fractional results are rounded down, e.g. avg16(20,41) = 30

Calculate an integer average of two unsigned 8-bit integer values (uint8_t). Fractional results are rounded down, e.g. avg8(20,41) = 30

-- Convert all pixels to RMT pulses This function is only used when the user chooses to use the built-in RMT driver, which needs all of the RMT pulses

Fast 16-bit approximation of cos(x). This approximation never varies more than 0.69% from the floating point value you'd get by doing float s = cos(x
