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
in codebuild,c, replace the existing i2c cad procedure with the fast_i2c procedure.
Candidates are listed below.
Criteria:
1) No cmd arg must be longer than 31 bytes.
2) fast_i2c mode (cmd and args are sent together) must be supported. Clarification: The controller must support the combination of cmd and arg together. This is probably the case for all controllers.
