/*

  generate and update c/c++ files
  this also replaces the buildcpp tool
  
  
  Dec 2018:
  There are now two SSD13xx cad procedures:
    u8x8_cad_ssd13xx_i2c			Put a I2C start/stop around each command and each argument	--> many start/stop commands
    u8x8_cad_ssd13xx_fast_i2c		Put a I2C start/stop around each command+arg sequence		--> start/stop is probably halfed --> 4% faster
