in bytes (1 byte = 8 bits). This however, isn't the amount of elements, in blink7, sizeof(array) will return 20. This is because every element is an int, and an int is 2 bytes long. So the total number of elements is

int getLastError()returns last (I2C) error. Adjusting the range of the INA226 use at own riskIn issue #26 a hack is made to scale the INA226 to 300A by using a very small shunt. The library has a minimal limit for the shunt of 0.001 ohm. This limit can be overruled to support ot...

int val = analogRead(ANALOG_IN); Serial.println(val); } This approach is not wrong and I do not want to insult anyone, but this is too slow for me. The serial port is slow and sending every result of an analogRead() through it is a bottleneck. ...
our I/O functions. If someone by mistake calls our function which expects pin code with plain pin number, for example,digitalWrite2f(13, HIGH);(ERROR!) instead ofdigitalWrite2f(DP13, HIGH);, the compiler will complain "invalid conversion from 'int' to 'GPIO_pin_t'". C...
