Challenges & objectives

Definition of the electronic architecture consisting of 7 boards (3 existing boards and development of 4 new boards)

    • Same form factor
    • Same performance
    • Same functions

Design of the 4 maps and schematics in KICAD

Placement/Routing with 3D file generation for mechatronic aspects in KICAD

C coding on PIC microcontroller (link between SPI ⬄ I2C bus and GPIO for HMI)

Support for TIFLEX’s Italian partner developing FPGA code for printhead control

Realization in controlled expenditure mode in our offices

Requirements

Reduced printhead footprint

Fast interface operation of 24 signals at 10MHz frequency without adding a protocol layer over a distance of 10m
