| 1 The project contained in this repository is a mechanism for capturing the | |
| 2 decoded 16-bit linear PCM form of voice call downlink on FreeCalypso boards | |
| 3 via MCSI, and for feeding 16-bit linear PCM into call uplink via the same | |
| 4 interface. The mechanism consists of a Lattice Icestick FPGA board, a gateware | |
| 5 image for this FPGA, and host programs that interface to it via the UART channel | |
| 6 of the on-board FT2232H. | |
| 7 | |
| 8 So far only downlink Rx has been implemented; to get the uplink path, more work | |
| 9 is needed on both FPGA gateware and software components. |
