To enhance the system reliability and maintainability, an integrated DC magnet power supply control board is designed to effectively consolidate several control functions into a unified whole. A Raspberry Pi Compute Module, a STM32 micron controller, an Intel CPLD as well as other functional ICs, such as energy measurement IC, ADCs and DACs, are embedded into a single board. The software implementation handles the control logic and communications among these ICs. An EPICS IOC runs inside the Raspberry Pi deals with the EPICS communication towards our main control network while the micro controller aggregates hardware status information from ICs and reports them to the IOC. The CPLD is mainly used for the interlock signal processing. The communication protocol design between those parts and programming practice experiences are introduced in this work.
