.SH NAME
pig2vd - A utility to convert pigpio notifications to VCD.
.SH SYNOPSIS
pig2vcd </dev/pigpioXX >file.VCD
.SH DESCRIPTION
pig2vcd is a utility which reads notifications on stdin and writes the
output as a Value Change Dump (VCD) file on stdout.
.br
.br
The VCD file can be viewed using GTKWave.
.br
.br
.SS Notifications
.br
.br
Notifications consist of 12 bytes with the following binary format.
.br
.br
.EX
typedef struct
.br
{
.br
uint16_t seqno;
.br
uint16_t flags;
.br
uint32_t tick;
.br
uint32_t level;
.br
} gpioReport_t;
.br
.EE
.br
.br
seqno starts at 0 each time the handle is opened and then increments
by one for each report.
.br
.br
flags, if bit 5 is set then bits 0-4 of the flags indicate a gpio which
has had a watchdog timeout.
.br
.br
tick is the number of microseconds since system boot.
.br
.br
level indicates the level of each gpio.
.br
.br
pig2vcd takes these notifications and outputs a text format VCD.
.br
.br
.SS VCD format
.br
.br
The VCD starts with a header.

.br
.EE
.br
.br
The header defines gpio identifiers and their name. Each gpio identifier
must be unique. pig2vcd arbitrarily uses 'A' through 'Z' for gpios 0
through 25, and 'a' through 'f' for gpios 26 through 31.
The corresponding names are 0 through 31.
.br
.br
.br
The VCD file may be edited to give a frendlier name, e.g. 8 could be
changed to ENCODER_A if an encoder switch A is connected to gpio 8.
.br
.br
Following the header pig2vcd takes notifications and outputs a timestamp
followed by a list of one or more gpios which have changed state.
The timestamp consists of a '#' followed by the microsecond tick.
The state lines contain the new state followed by the gpio identifier.

.SH NAME
pigpiod - A utility to start the pigpio library as a daemon.
.SH SYNOPSIS
sudo pigpiod [OPTION]...
.SH DESCRIPTION
pigpiod is a utility which launches the pigpio library as a daemon.
.br
.br
Once launched the pigpio library runs in the background accepting commands from the pipe and socket interfaces.
.br
.br
The pigpiod utility requires sudo privileges to launch the library but thereafter the pipe and socket commands may be issued by normal users.
.br
.br
pigpiod accepts the following configuration options
.br
.br
.SH OPTIONS
.IP "\fB-b value\fP"
gpio sample buffer in milliseconds
100-10000
default 120
.IP "\fB-d value\fP"
primary DMA channel
0-14
default 14
.IP "\fB-e value\fP"
secondary DMA channel
0-6
default 5
.IP "\fB-f\fP"
disable fifo interface
default enabled
.IP "\fB-k\fP"
disable socket interface
default enabled
.IP "\fB-p value\fP"
socket port
1024-32000
default 8888
.IP "\fB-s value\fP"
sample rate
1, 2, 4, 5, 8, 10
default 5
.IP "\fB-t value\fP"
clock peripheral
0=PWM 1=PCM
default PCM
.IP "\fB-u value\fP"
clock source
0=OSC 1=PLLD
default PLLD
.IP "\fB-x mask\fP"
gpios which may be updated
A 54 bit mask with (1<<n) set if the user may update gpio #n.
default is the set of user gpios for the board revision
.br
.br
.SS Example
.br
.br
.EX
sudo pigpiod -s 2 -b 200 -f
.br
.EE
.br
.br
Launch the pigpio library with a sample rate of 2 microseconds and a 200 millisecond buffer. Disable the fifo interface.
.br
.br
.SS Permissions
.br
.br
pigpio provides a rudimentary permissions system for commands issued via the socket and pipe interfaces.
.br
.br
All gpios may be read.
.br
.br
Only the default gpios for the board revision or those specified by the -x option may be updated.
.br
.br
.EX
Revision 1 boards 0x03E6CF93
.br
Revision 2 boards 0xFBC6CF9C
.br
Revision 3 boards 0x0FFFFFFC
.br
.EE
.br
.br
In this context an update includes the following:
.br
.br
gpio mode set
.br
gpio pull/up down
.br
gpio write
.br
gpio set PWM (including range and frequency)
.br
gpio set servo
.br
.br
In addition the bank clear and set commands, and the wave commands will only
affect updateable gpios.
.br
.br
There are two special cases.
.br
.br
The activity LED may be written (gpio 16 for Rev.1/2
boards, gpio 47 for Rev.3 boards).
.br
.br
The high USB power mode gpio may be written (gpio 38 for Rev.3 boards).
