# TinI/O
|
|
|
|
is a tool for interfacing the Cypress CY7C65211 USB-Serial Bridge Controller and its GPIO.
|
|
|
|
--------------------------------------------------------------------------------
|
|
|
|
## 1\. How to build it
|
|
|
|
To set up TinI/O, you'll need:
|
|
|
|
- A linux machine (the processor architecture doesn't matter, but Debian or Ubuntu is almost guaranteed to work)
|
|
- an USB dongle with the chip
|
|
- a C and C++ compiler (GCC is most common)
|
|
- GNU Make and CMake
|
|
- libusb 1.0
|
|
|
|
You can build TinI/O by
|
|
|
|
a)`cd`-ing to the `cylib/build` directory and build the needed libraries with:
|
|
|
|
```
|
|
# cmake ..
|
|
# make
|
|
# sudo make install
|
|
```
|
|
|
|
Then go to the `../tinio` directory and build and install TinI/O with:
|
|
|
|
```
|
|
# make
|
|
# make install
|
|
```
|
|
|
|
or<br>
|
|
b) executing the `autobuilder` script in the main directory that will do the above for you.
|
|
|
|
**NOTE: Although the autobuilder should be working in most use cases, it's still better to build the tools manually (if you have the needed knowledge, of course)**
|
|
|
|
## 2\. Getting started
|
|
Before you start using TinI/O, you have to reflash the target chip so it can be recognised by your PC. That is done with the supplied `cy-config` utility.
|
|
To reflash a chip, you'll need to navigate to `/usr/share/tinio/flashes` directory. There you'll find files that contain different flash images. (I'll say more about the images later in the chapter TODO)
|
|
For a general configuration (5 inputs, 5 outputs), we'll use TODO
|
|
You can get a quick summary on TinI/O by executing it.
|
|
|
|
```
|
|
# ./tinio
|
|
TinI/0 0.1
|
|
Usage:
|
|
tinio <options>
|
|
The supported options are:
|
|
-d<device number> - specifies the desired device - integer 0 to 15
|
|
-i<interface number - specifies the USB interface number - integer 0 to 255
|
|
-s<pin number> - sets the specified pin to the value specified with -v - integer 0 to 11
|
|
-r<pin number> - reads the specified pin's value and prints it to the stdout - integer 0 to 11
|
|
-v<value> - value for -s option - integer 0 to 1
|
|
-e - enables expert mode (enables protected pins)
