# d2xx
|
|
|
|
Package d2xx is a thin Go wrapper for the Future Technology "D2XX" driver at
|
|
https://ftdichip.com/drivers/d2xx-drivers/.
|
|
|
|
This package is not Go idiomatic. You will want to use
|
|
https://periph.io/x/host/v3/ftdi (or later) instead.
|
|
|
|
But if you really want, here it goes:
|
|
[](https://pkg.go.dev/periph.io/x/d2xx)
|
|
|
|
This Go package includes third party software. See
|
|
[third_party/README.md](third_party/README.md).
|
|
|
|
## Configuration
|
|
|
|
See https://periph.io/device/ftdi/ to configure the host to be able to use this
|
|
driver.
|
|
|
|
## Availability
|
|
|
|
On darwin_amd64, linux_amd64 linux_arm (v6, v7 compatible) and linux_arm64 (v8),
|
|
cgo is required. If cgo is disabled (via `CGO_ENABLED=0`), all functions in this
|
|
driver return error [NoCGO](https://periph.io/x/d2xx#NoCGO).
|
|
|
|
On Windows, cgo is not required. If the dynamic library is not found at runtime,
|
|
[Missing](https://periph.io/x/d2xx#Missing) is returned.
|
|
|
|
## bcm2385
|
|
|
|
On linux_arm (v6), hard-float is required. For cross compilation, this
|
|
means arm-linux-gnueabihf-gcc is preferred to arm-linux-gnueabi-gcc. Using
|
|
hardfloat causes a segfault on Raspberry Pi 1, Zero and Zero Wireless. It is
|
|
recommended to disable this driver if targeting these hosts, see below.
|
|
|
|
## Disabling
|
|
|
|
To disable this driver, build with tag `no_d2xx`, e.g.
|
|
|
|
```
|
|
go install -tags no_d2xx periph.io/x/cmd/gpio-list@latest
|
|
```
|
|
|
|
This will behave has if cgo was disabled, even on Windows.
