h3. design files

We originally started with a prototype from an iCE40 evaluation board plus two osmo-e1-xcvr and one e1-tap as described in [[ICE40_based_passive_tap]].

Meanwhile, we have designed a fully integrated board.  Design files are part of the @osmo-e1-xcvr.git@ repository.

h3. gateware + firmware

The FPGA gateware and RISC-V softcore firmware are found in the @e1-recorder@ branch of @ice40playground.git@, see https://github.com/smunaut/ice40-playground/tree/e1-recorder

h3. availability

Fully assembled products based on this hardware are going to be made available by "sysmocom":https://sysmocom.de/

h2. software

The host software is found in the @e1-recorder@ branch of @ice40playground.git@, see https://github.com/smunaut/ice40-playground/tree/e1-recorder/projects/riscv_usb/sw

There are two related programs:

* @main@ - the program used to perform recordings and store them

* @dump@ - the program to analyze recordings
