The RASPIVEND has an internal cash counter which is incremented for each bill or coin
deposited by the MDB PERIPHERALS. This counter can be read by using a POLL
command, detailed on “12. Poll credit and devices status”. For simplicity reasons, this
counter can be reseted by this command. You can use this command after each
transaction, or anytime you need.
