a vote) and sends status information back to the clients (e.g. The WebSockets Listener is responsible for listening for incoming WebSockets connections (TCP/IP) and launching instances of the WebSockets Connection Handler VI when there’s a valid connection.Īn instance of the Connection Handler VI is asynchronously launched for each client connection – it listens for incoming WebSockets messages (e.g. The small timer loop is used to trigger the message handler loop to check the remaining time. The tracking of voters is done using the Sets & Maps API added in LabVIEW 2019 – I hadn’t yet had chance to try these out but as someone that quite often uses Variant Attributes for lookup tables/dictionaries they seem like an excellent replacement. The main message handler is responsible for handling incoming votes, keeping track of players/votes/scores and sending commands to the servo loop.
#Labview evaluation version code#
The code uses our internal QMH library – this is based on the NI Template but with some additional functions and templates. The architecture is a Queued-Message-Handler with multiple loops. The LabVIEW current-gen (2019+) code uses the LINX Toolkit to develop code that can run on the Raspberry Pi. Raspberry Pi Code (LV2019 / LV 2020 Community Edition) There is also an admin interface which is used to enable/disable the servo drive and display the leaderboard. The player interface is written using a couple of LabVIEW NXG WebVIs – the player interface allows players to connect using their phones/tablets and cast their votes in real-time.
#Labview evaluation version software#
The software consists of a LabVIEW 2019 (or LabVIEW 2020 Community Edition) project for the code running on the Raspberry Pi – the Raspberry Pi runs the LabVIEW code as a deployed RT Executable and listens for incoming player connections (using WebSockets), handles the voting aspect and controls the servos to enact the winning vote.
