Detailed Description

QEP/C port to QK for a "generic" C compiler.

Note:

This is just an example of a QEP port used for "linting" the QEP. Ports of QEP are located in the directory <qpc_3>/ports.

Define Documentation

#define QEP_SIGNAL_SIZE   1

The size (in bytes) of the signal of an event. Valid values: 1, 2, or 4; default 1.

This macro can be defined in the QEP ports to configure the QSignal type. If the macro is not defined, the default of 1 byte will be chosen in qep.h. The valid QEP_SIGNAL_SIZE values of 1, 2, or 4, correspond to QSignal of uint8_t, uint16_t, and uint32_t, respectively. The QSingal data type determines the dynamic range of numberical values of signals you your application.

QEvent

Note:

Once you choose a certain value of QEP_SIGNAL_SIZE, you must consistently use the same value in building all the QP component libraries and your own application code. The consistency is guaranteed if you define this macro only once in the qep_port.h header file and henceforth include this header file in all builds.
