# Description

***NOTE:*** Current master branch (version 1) will not get any updates anymore. I am working on version 2 of these tools since I got fed up with the hard maintainability of the old code written over last decade. I will release the new version to master branch when I am happy with the new code.

***UPDATE (2022-05):*** v2 was in good progress but I have been busy with other things, maybe someday it is finished

## Command line tools

* ftdi-bitbang
* ftdi-control
* ftdi-hd44780
* ftdi-simple-capture
* ftdi-spi *(coming, does not work yet)*

* libftdi-bitbang
* libftdi-hd44780

## Compile

```sh

# ftdi-simple-capture
Do simple digital data capturing using FTDI FTx232 chips.
Can be used to analyze digital circuit with or without trigger.
Example use case would be to capture IR signal at pin #0,
trigger on rising edge and capture 500 mS,
then feeding it to external script which would filter it as ones and zeroes and so on.
```
Usage:
 ftdi-simple-capture [options]

Definitions for options:
 ID = hexadecimal word
 PIN = decimal between 0 and 15
 INTERFACE = integer between 1 and 4 depending on device type

  -h, --help                 display this help and exit
  -V, --vid=ID               usb vendor id
  -P, --pid=ID               usb product id
                             as default vid and pid are zero, so any first compatible ftdi device is used
  -D, --description=STRING   usb description (product) to use for opening right device, default none
  -S, --serial=STRING        usb serial to use for opening right device, default none
  -I, --interface=INTERFACE  ftx232 interface number, defaults to first
  -U, --usbid=ID             usbid to use for opening right device (sysfs format, e.g. 1-2.3), default none
  -R, --reset                do usb reset on the device at start
  -L, --list                 list devices that can be found with given parameters

-p, --pins=PINS[0-7]       pins to capture, default is '0,1,2,3,4,5,6,7'
  -t, --trigger=PIN[0-7]:EDGE
                             trigger from pin on rising or falling edge (EDGE = r or f),
                             if trigger is not set, sampling will start immediately
  -s, --speed=INT            sampling speed, default 1000000 (1 MS/s)
  -l, --time=FLOAT           sample for this many seconds, default 1 second

Simple capture command for FTDI FTx232 chips.
Uses bitbang mode so only ADBUS (pins 0-7) can be sampled.
