Project 2019-2020 - Custom Data Interface
Description
Specific paralel to RS485 defined protocol conversion for two independent customer's instruments.
Full design process from concept to production, based on customer requirements and mechanical definitions.
Circuit design: self diagnostic (power consumption monitor), USB, RS485, Analog In/Out, digitally controlled DCDC converter.
Core MCU: LPC1549
