This project is 3-in-1. First it's a RESTful API I built using Go to send and receive requests from webpages, these requests can either get the current temperature readings from the Lakeshore or turn specific heaters on. Second, the Go code also interfaces with the Lakeshore controller across the serial-port to actually achieve the goals of the API. This could be done over TCP but due to some concerns we went with the physical connection instead. And 3rd, the Go code also serves a webpage I built that responsively displays temperatures from different sensors in Real-time and allows them to control the temperature if they wish. This was all done at the CLS this past summer.
Installation Instructions for Raspberry Pi: TODO: Make this simpler
- clone this repo and move mux_lakeshore and static/ into the same directory on your pi
- Run "sudo chmod +x mux_lakeshore" and then you should be able to run the executable
- Enjoy real-time remote monitoring and control over the Lakeshore controller.
If you're running it on windws, api_server.exe may work. Try recompiling if there is an error.
Important note: You may have to change api_server.go code to reflect the USB-serial port your pi assigned to the Lakeshore controller. In which case you'd need to cross-compile mux_lakeshore again. This is very simple, and you can find out more about that and more dev stuff in the dev.md
TODOS:
Adjust UX slightly. It isn't the best right now.
Do further testing on writing the heater commands to the controller.
