This is a work in progress on it's early stages, expect errors and changes.

RECOMMENDED ENVIRONMENT

The code is developed in Visual Studio 2019 community edition.

• To develop the Arduino firmware I have used Visual Micro: https://www.visualmicro.com/
• To develop the Spectrum programs I have used SpectNetIDE with Boriel Basic:

• https://github.com/Dotneteer/spectnetide
• https://github.com/boriel/zxbasic

From my experience this setup is gorgeous, only one IDE for all the system.

The software:

• ZXShield: framework to develop the ZXShield firmware.
• Devices: Shared library to handle various devices like the ESP01 module or the MCP42XXX family of digital potentiometers.
• ZXComms: Peripheral example, it creates a WiFi card for the ZX Spectrum. Needs a ZXShield and a ESP01 module.
• ZXBasicROM: Pasive ROM example. It includes the 48k rom already converted for the system.
• ZXRegisterManager: ZX Spectrum program to make IO requests easily. Very useful to develop and test new devices.
• ZXTelnet: ZX Spectrum telnet client. Used with the ZXComms device.
• ZXSerialLoaderFirmware: Arduino firmware to load .HEX and .SNA files from PC
• ZXSerialLoaderClient: Console app to send .HEX and .SNA files
• ZXSerialLoaderROM: SpectNetIDE project with the programs injected on the speccy to load programs from PC
• GeneraROMRAM: Program to convert the .HEX files generated by ZXSerialLoaderROM into program arrays

The hardware:

Well, the first PCB is in production, next week will arrive, once it's tested if all is OK i will add the KiCad project to the repository, for now get a peek to it.
