gcc 13 moved some includes around and as a result <cstdint> is no longer transitively included [1]. Explicitly include it for uint{32,64}_t.

|
|
*
|
|
* The MiCS-VZ-86/89 combines state-of-the-art MOS sensor technology with
|
|
* intelligent detection algorithms to monitor VOCs and CO2 equivalent
|
|
* variations in confined spaces.
|
|
*
|
|
* The MICSV89 comes in 4 variants, PWM and I2C in 3.3 volts and 5 volts.
|
|
* This library only implements the I2c version of the device.
|
|
*
|
|
* Device output is not valid until a warm up of 15 minutes of operation.
