Driving method of thermal foaming ink box

The invention relates to a driving method of a thermal foaming ink box. The driving method comprises the following steps: a first group of data: preparing an address counter to reset; in the second group of data, an address counter is reset, and TA1 address data is prepared; according to the third group of data, an address counter adds one to point to a TA1 address, TA1 data are ejected, and TA2 address data are prepared at the same time; according to the fourth group of data, an address counter adds one to point to a TA2 address, TA2 data is ejected, and TA3 address data is prepared at the same time; and so on, until the last group of data is completed, jet printing of all addresses is completed, and printing of the ink box array is completed. According to the technical scheme, only a three-line SPI bus of a common MCU is needed for driving, IO resources of the MCU can be greatly saved, the ink box can be directly used as an SPI slave device only by making a data sending rhythm, writing of ink box software b
