Can't install purr-data on Manjaro
Hey, I'm trying to get purr-data to work on my fresh Manjaro XFCE install, but it does not work. Any help is greatly appreciated!

Having lots of switches into Pd
@alexandros said:
Have you detected whether the crash happens with
else if (in == 'd')
orelse if (in == 'p')
?
It happens only in else if (in == 'p')
. When I bypass that I can update snapshot~ by 1 ms (I assume that 'c' will still be sent by 1 ms intervals).
In the Pd patch it's probably better to swap the $1 and $2 values in the messages. Have the channel set in a cold inlet and the value in a hot one and then write this message
print $2c$1v
Ok I did that.
I see in the screenshot of the patch that the PWM message is not connected to [comport]. Is this for some particular reason?
It is to make sure Pd does not crash/freeze until I want to try the code.
Maybe the 10ms interval for sending a PWM value to [comport] is a bit too fast. Did you try something slower, like 50ms?
That made it work. If I use six pwm pins the limit is 150 ms before crash.
Question 1: Could there something bad that happens around else if (in == 'p')
? In another code snippet you used this format:
while(Serial.available()){
byte inByte = Serial.read();
if((inByte >= '0') && (inByte <= '9'))
temporary = 10 * temporary + inByte - '0';
else{
if(inByte == 'p'){
pwmLEDvalue = temporary;
temporary = 0;
}
else if(inByte == 'd'){
dspLEDstate = temporary;
temporary = 0;
}
}
analogWrite(pwmLED, pwmLEDvalue);
digitalWrite(dspLED, dspLEDstate);
}
compared to this in the current sketch:
if (Serial.available()) {
static int temp;
byte in = Serial.read();
if (isDigit(in)) temp = temp * 10 + in - '0';
else if (in == 'c') {
channel = temp;
temp = 0;
}
else if (in == 'd') {
digitalWrite(outPins[channel], temp);
temp = 0;
}
else if (in == 'p') {
analogWrite(pwmPins[channel], temp);
temp = 0;
}
}
Question 2: Is this crash of Pd and the computer (macOS Mojave) expected behavior in a situation like this? If it is not, maybe it should be reported as a bug. It happens consistently.
Thoughts: Could there be a problem in [comport]? This crash behavior is identical with the problems I had when using Pdunio/Firmata.

Another thing would be to try and merge messages for digital and PWM. Since PWM happens automatically, you could append the digital pin message and send something like print $2c$1p$4c$3d
where $4 will be the digital pin channel and $3 the value.

Thank you for replying and sorry if I am unclear. I will try to slow down a bit.
@alexandros said:
@cfry definitely not necessary to use two Arduinos. I can't really understand where your problem lies.
-The problem is that it does not work when I try to use an arbitrary combination of pins in different modes (Digital in, Digital out, Analog in, Analog out).
Another problem is that I have a hard time reading the code parts that are handling the conversion data in order to do the serial communication, although I understand the principle of it.
You didn't reply to my earlier question about the pinMode calls where you use INPUT_PULLUP on analog inputs. Is this really necessary?
-I assumed that the problem lied in void ()loop as a conflict between the output and input handling sections. And that pinMode calls in void setup() was not relevant in this case. That is why I did not answer that question directly.
Also, why not use the analog pins in an array like with the digital pins? It will save a lot of writing and it's less error prone.
-I was foreseeing that I may want to configure those pins individually, but I can set it up with a loop for now.
One thing you might want to consider is having the Arduino notify Pd when it's done sending all its data and that it's ready to receive. That could be done at the end of the loop() function like this:
Serial.print("done "); Serial.println("bang");
And in Pd have a [r done] object which will output a bang. Use this bang to send data from Pd to the Arduino by unpacking a list with all the accumulated data, possibly with a [list-abs/list-drip].
I use this notification technique in my 3dPdModular system, but there's a LOT of data there and it was only necessary. Perhaps you could try it out.
-I will try that.
Since I consider this to be basically your code I assumed that you could easily just insert the code for both input and output in void loop() in a way that works and that would show me how to solve it. Then I would be able to do further explorations and it would be end of story.
I will digest this a bit and may start a new thread, since this one has slided from "Having lots of switches into Pd" to "having a working code template for communicating between Arduino and Pd using and an arbitrary mixture of pin modes".
Please let me know if this still does not make sense. Thank you so much!

@alexandros now pwm and digital output work fine, but when I try to merge with digital and analog inputs it goes wrong. the leds flicker randomly. If you remove the code below
// do input pins:
flicker stops. :/
int outPins[3] = {2, 4, 7};
int pwmPins[6] = {3, 5, 6, 9, 10, 11};
// a global variable to hold which LED we want to control (either digital or PWM)
int channel = 0;
int inPins[2] = {12, 13};
int analogPins[8] = {0, 1, 2, 3, 4, 5, 6, 7};
void setup() {
for (int i = 0; i < 3; i++) {
pinMode(outPins[i], OUTPUT);
}
for (int i = 0; i < 6; i++) {
pinMode(pwmPins[i], OUTPUT);
}
for(int i = 0; i < 2; i++) {
pinMode(inPins[i], INPUT);
}
pinMode(A0, INPUT_PULLUP);
pinMode(A1, INPUT_PULLUP);
pinMode(A2, INPUT_PULLUP);
pinMode(A3, INPUT_PULLUP);
pinMode(A4, INPUT_PULLUP);
pinMode(A5, INPUT_PULLUP);
pinMode(A6, INPUT);
pinMode(A7, INPUT);
//DEFAULT works with thermistors,
//INTERNAL with transitor thermostats
analogReference(DEFAULT);
Serial.begin(115200);
}
void loop() {
//do output pins:
if (Serial.available()) {
static int temp;
byte in = Serial.read();
if (isDigit(in)) temp = temp * 10 + in - '0';
else if (in == 'c') {
channel = temp;
temp = 0;
}
else if (in == 'd') {
digitalWrite(outPins[channel], temp);
temp = 0;
}
else if (in == 'p') {
analogWrite(pwmPins[channel], temp);
temp = 0;
}
}
// do input pins:

First of all, don't separate functions for reading the serial data, even if you want to read data for different kinds of stuff.
Combining digital with PWM pins should be sort of straight forward. Here's some example code:
int digitalPins[4] = {2, 4, 7, 10};
// use an array for all the pins of similar type, e.g. PWM pins, like below
int pwmPins[6] = {3, 5, 6, 9, 11, 12}; // can't remember the exact pin numbers with PWM, change accordingly
// a global variable to hold which LED we want to control (either digital or PWM)
int channel = 0;
void setup() {
for (int i = 0; i < 4; i++) {
pinMode(digitalPins[i], OUTPUT);
pinMode(pwmPins[i], OUTPUT);
Serial.begin(115200);
}
void loop() {
if (Serial.available()) {
static int temp;
byte in = Serial.read();
if (isDigit(in)) temp = temp * 10 + in - '0';
else if (in == 'c') {
channel = temp;
temp = 0;
}
else if (in == 'd') {
digitalWrite(digitalPins[channel], temp);
temp = 0;
}
else if (in == 'a') {
analogWrite(pwmPins[channel], temp);
temp = 0;
}
}
Check this code with Pd by sending messages of the type print $1c$2d
for digital values and print $1c$2a
for analog values. $1 is the led number (incrementing, starting from 0), and $2 is the value you want to write, 0-1 for digital and 0-255 for PWM.

I am aiming at using same type of array handling as for the digital outs.
Thanks a lot
Having lots of switches into Pd
Hi, I am trying to add the code for pwm control (from tutorial 5) to the code above but I can not get it to work. Could you help me out plz? I would like to use 6 pwm outputs so I figure it should be set up as the other digital outputs.
Having lots of switches into Pd
I would suggest to not mix the analog values with the digital ones. The first code could be changed to the following (using Serial.print() with the [serial_print] abstraction):
void setup()
{
for(int i = 2; i < 14; i++)
pinMode(i, INPUT);
Serial.begin(115200); // perhaps use a faster baud rate
}
void loop()
{
Serial.print("knobs"); // use "knobs" as a keyword so you can receive
// the knob values as a list with a [r knobs] in Pd
for(int i = 0; i < 6; i++){
unsigned int knob = analogRead (i);
Serial.print(" "); // first print a white space to separate the "knob" keyword from the values
// and the values from each other
Serial.print(knob); // then print the actual knob value
}
Serial.println(); // finally print a newline character to denote end of data for keyword "knobs"
// the same technique applies to the switches too
// receive the switch values as a list with [r switches]
Serial.print("switches");
for(int i = 2; i < 14; i++) {
int switchVal = digitalRead(i);
Serial.print(" ");
Serial.print(switchVal);
}
Serial.println();
}
As for writing to several outputs you need to set which output you want to write to and then the value you want to write. Here's an example that writes to several different digital outputs:
int pin = 0;
int val = 0;
// some random pins
int pins[4] = {3, 4, 5, 6];
void setup() {
for (int i = 0; i < 4; i++) {
pinMode(pins[i], OUTPUT);
digitalWrite(pins[i], LOW);
}
Serial.begin(115200);
}
void loop() {
if (Serial.available()) {
static int temp;
byte in = Serial.read();
if (isDigit(in)) {
temp = temp * 10 + in - '0';
}
else if (in == 'p') {
pin = temp;
temp = 0;
}
else if (in == 'v') {
val = temp;
temp = 0;
digitalWrite(pins[pin], val);
}
}
With the code above you can send messages like this one print $1p$2v
in Pd to the [comport] object. $1 is the number of the pin you want to light up starting from 0 and incrementing by 1 (so the first pin used which is pin 3 in the Arduino code would be 0 in the Pd patch), and $2 is the value, 0 or 1.
Note though that in the first code (and the code you posted), you're using all digital pins as inputs so there's no pin left to use as output. If you want to combine these two chunks of code you'll have to use less pins as inputs and leave some to be used as outputs.
Self-listening app
Once again -- probably the distortion is coming from outside of Pd.
The signal flow is like this:
-
The mic converts air pressure variations into an analog electrical signal.
-
A pre-amplifier in the soundcard adjusts the volume in the analog domain.
-
The ADC converts the analog signal to digital.
-
The OS pipes the digital signal to Pd.
My guess is that the signal is too loud at #2. If so, then the ADC (#3) will produce a distorted (clipped) signal. After this -- understand this clearly -- there is nothing you can do in the digital domain to fix it.
It's critical to be sure the recording volume in the soundcard is set correctly. The recording volume must be adjusted before sampling. Pd gets the audio after sampling, so your patch can't do anything about it.
I'd actually said this a week ago but, glancing over the thread, nowhere does anybody say "I set the mic level." So I think probably you haven't done it... but this is the first thing to check when a mic is distorting.
If it's a built-in soundcard, the volume will be a system setting. If it's an external soundcard, it will be a knob on the external unit.
