## Building your binary
The binary built in the base recipe doesn't have SDC drivers. Using the same
instructions as in the `eeprom` recipe, you'll need to assemble a binary with
those drivers. First, we need drivers for the SPI relay. This is done by
declaring `SPI_DATA`, `SPI_CSLOW` and `SPI_CSHIGH`, which are respectively `4`,
`5` and `6` in our relay design. You can then load the driver with `596 LOAD`.
This driver provides `(spix)`, `(spie)` and `(spid)` which are then used in the
SDC driver.
The binary built in the base recipe doesn't have SDC drivers. You'll need to
assemble a binary with those drivers. To do so, you'll modify the xcomp unit
of the base recipe. Look at `xcomp.fs`, you'll see that we load a block. That's
our xcomp block (likely, B599). Open it.
