Rust Embedded firmware using rust embedded-hal<sup>1</sup> and embassy-rs<sup>2</sup> on STM32G030C8<sup>3</sup> MCU for Billmock product.
Used rust experimentally.
This repository is aiming three goal. One for development of production firmware and second is making a proof of concept that rust embedded is usable for actual embedded production. And last goal is setting some example about production-rust-embedded-code.
This project is currently under development, with ongoing QA testing and some optimization remaining.
Billmock
Detail documentation is here BillMock Manual
It is hardware and software for the purpose of converting I/O signals related to money payment of arcade game machines for compatibility.
This project began development at the request of GPARK Co., Ltd<sup>4</sup> and was designed and developed for the using credit card readers in arcade game machine and compatibility of existing payment systems (open-drain-based), and is open to the public except for code in the NDA area. The project has been granted an open source disclosure except of NDA era.
Target Hardware
Based on BillMock-HW 0.5 mini, 0.4 mini and 0.4. <br/> 0.2 and 0.3 HW bring-up codes are still left for recyle the old PCB.
- 0.2 HW has different gpio configuration compare to latest boards.
- 0.3 HW has minor bugs, floating on VendSide-Inhibit and missing net route on VendSide-1P-StartJam.
- 0.4 HW fixed 0.3 HW bugs.
- 0.4 HW mini reduced BOM for mass-manufacturing
- 0.5 HW mini added tact switch for SVC mode call
Current default HW is 0.5 mini. If need to use old 0.4 or 0.4 mini, following below command lines
cargo build --features hw_0v4 --no-default-features --release
cargo build --features hw_mini_0v4 --no-default-features --release
Target hardware image
The hardware revision currently adopted for final mass production is 0.5-MINI, and the software development is also progressing according to this version.
Old revisions.
