No need to wait after Wire.requestFrom(). #16

Open Koepel opened 5 years ago

Koepel commented 5 years ago

In the files:

M5-ProductExampleCodes/Hat/tof-hat/Arduino/ToF_Count/ToF_Count.ino
M5-ProductExampleCodes/Unit/TOF/Arduino/MeasureDistance/MeasureDistance.ino
M5-ProductExampleCodes/Unit/TOF/Arduino/TOF_VL53L0X/TOF_VL53L0X.ino

there is waiting after a Wire.requestFrom(). You may remove all these lines: while (Wire.available() < 1) delay(1);

In the files:

M5-ProductExampleCodes/Unit/ENV/Arduino/ENV/DHT12.cpp
M5-ProductExampleCodes/Core/m5go/m5go_lite/Arduino/ENV/DHT12.cpp

there is a delay after the Wire.requestFrom(). That is delay is not needed for interfacing with the Wire library.

In the file:

M5-ProductExampleCodes/Unit/EXTIO/Arduino/EXT_IO/PCA9554.cpp

you may remove this line: while (Wire.available() < 1);
