This repository stores sample code for the Bridgetek FT9xx series which implement emulations of USB devices.
The FT9xx has a hardware library which is used to access to the built-in USB device hardware. The library is installed with the FT9XX Toolchain. Source code for the library and general purpose example code are included with the toolchain and but these can also be accessed via GitHub (Bridgetek/ft90x-sdk)[https://github.com/Bridgetek/ft90x-sdk].
Source code for other USB device examples are available as Application Notes from the Bridgetek website.
The repository contains sample code for the following:
- USBD Example Composite - Creates a device with a Keyboard interface, MIDI interface and optional DFU interface. The keyboard and MIDI interfaces can be set to send pre-programmed data to the host to cause typing to appear on the host and play a tune to a MIDI controlled program.
- AN_414 FT90x_USBD_UVC_Webcam - Creates a USB device emulating a UVC webcam using the built-in camera interface of the FT90x and OV965x or OV5640 sensor. The FT90x appears as a Camera device and streams compressed or uncompressed data to the host PC. Compressed streams are only supported if the sensor supports a compressed output. See (Application Note AN_414)[https://brtchip.com/wp-content/uploads/sites/3/2021/07/AN-414-FT90x-UVC-WebCam.pdf]
- BRT_AN_018 FT90x Camera to EVE - Displays the output of the built-in camera interface of the FT90x and OV5640 sensor on an EVE module. See (Application Note BRT_AN_018)[https://brtchip.com/wp-content/uploads/sites/3/2021/07/BRT_AN_018-FT90x-Camera-to-EVE.pdf]
The following documents are available from the BRTChip website:
- FT90X User Manual. This manual provides details about the peripherals of the FT90X Revision C as well as the general system registers.
- Toolchain Installation Guide. Installation guide for the gcc compiler, Eclipse plugins, hardware libraries and examples for the FT9xx series.
- Hardware API Programmers Manual. Documentation for the Hardware API for FT9xx series. This describes the API with hardware-specific libraries for the FT90x and FT93x to facilitate accessing peripherals. Prebuilt libraries and source code are installed with the toolchain.
- Assembly Language Programming. A guide for writing code fragments in assembler for the FT90x. Other documents are linked to in the FT90X Produce Page on the Bridgetek website.
Example code for the hardware API is included in the toolchain installation.
- Example Applications. This guide describes each of the example codes.
- Further example code can be found on the FT90x Software Examples
