Software DesignsSoftware Designs
• User Access
– Doctor and client modes
– Windows GUI client application
– View data and modify settings
• Database (MySQL)
– Accessible by firmware and client software
Multi-User DesignMulti-User Design
• Each user is identified by an unique ID
• Each patient is associated to a machine by machine ID
• Data sent and store to the database according to user and machine ID pair
• User switching by changing user and machine ID association
Hardware/FirmwareHardware/Firmware
• Incompatible temperature sensor SPI interface
• Limited external interrupt
• Integration Problem
Software/DatabaseSoftware/Database
• Communication with microcontroller
– User switching
• Many-to-many association between doctors and patients
