# interface2
|
|
|
|
Modern interface using a Lattice iCE40 FPGA and STM32 microcontroller.
|
|
|
|
|
|
|
|
## Hardware
|
|
|
|
You can find a [complete BOM](https://octopart.com/bom-tool/S80JaI18) on Octopart.
|
|
|
|
You can find the Gerber files for fabricating a PCB in the [fabrication](pcb/fabrication) directory. I have used JLCPCB to make the PCBs.
|
|
|
|
## FPGA
|
|
|
|
For now, the FPGA bitstream must be built using Lattice iCEcube2.
|
|
|
|
```
|
|
cd fpga
|
|
make
|
|
```
|
|
|
|
Uses FIFO module from [Sylvain Munaut](https://github.com/smunaut).
|
|
|
|
## Firmware
|
|
|
|
The firmware currently provides the ability to send commands and receive responses - it is designed to implement a terminal controller, not a terminal.
|
|
|
|
You will need [PlatformIO](https://platformio.org/) to build and upload the firmware, only Platform IO Core (the CLI) is required.
|
|
|
|
Before building the firmware, you will need to generate the FPGA bitstream; see the steps above.
|
|
|
|
To build and upload the firmware using USB DFU:
|
|
|
|
```
|
|
cd firmware
|
|
platformio run -t upload
|
|
```
