Where are the error codes listed?

This library works fine for me, except in the beginning and randomly distributed throughout I will receive 4 digit error codes. Where can I look these up? Thanks.

You will find all error code in the header file SimpleDHT.h.

// High 8bits are time duration.
// Low 8bits are error code.
// For example, 0x0310 means t=0x03 and code=0x10,
// which is start low signal(0x10) error.
// @see https://github.com/winlinvip/SimpleDHT/issues/25
#define simpleDHTCombileError(t, err) ((t << 8) & 0xff00) | (err & 0x00ff)

// Success.
#define SimpleDHTErrSuccess 0
// Error to wait for start low signal.
#define SimpleDHTErrStartLow 0x10
// Error to wait for start high signal.
#define SimpleDHTErrStartHigh 0x11
// Error to wait for data start low signal.
#define SimpleDHTErrDataLow 0x12
// Error to wait for data read signal.
#define SimpleDHTErrDataRead 0x13
// Error to wait for data EOF signal.
#define SimpleDHTErrDataEOF 0x14
// Error to validate the checksum.
#define SimpleDHTErrDataChecksum 0x15
// Error when temperature and humidity are zero, it shouldn't happen.
#define SimpleDHTErrZeroSamples 0x16
// Error when pin is not initialized.
#define SimpleDHTErrNoPin 0x17

If you have the error code 4112, it means 0x1010 in hex. So, the time duration is 0x10 and the error in Error to wait for start low signal.

Hope it helps ;-)

Thank you! I found the hex error codes but I didn't know that the time duration was in the front!
