DESCRIPTION

k8055m_get_digital_in returns the status of the specified port. k8055m_get_digital_in_all returns the status of all digital input ports as a bitmap. Port numbers are 0 .. 4.

These functions do not actually communicate with the card. They simply return the last status, the background thread started by k8055m_open() has received. Use k8055m_poll() to avoid a busy loop.
