Hi everyone,

I'm trying to run the (modified) FlipFlop Tutorial from the documentation on a Raspberry Pi 2 B. The FlipFlip itself works fine, but I cannot get the QX FB to activate the GPIO Pins, so the LED won't blink.

System configuration
index.php/fa/25089/0/

index.php/fa/25089/0/

Debug Mode: QX FB shows N/A on all ports
index.php/fa/25090/0/

index.php/fa/25090/0/

wiringPi seems to work fine, I can switch the LED on and off manually with
gpio mode 8 out
gpio write 8 1
gpio write 8 0

I run forte on the raspberry with root
sudo ./forte

Any idea what I'm missing?
Thanks so much, Max Smile

Hi,

Which version of FORTE are you using? Do you get an UNSUPORTED_TYPE error during download? For FORTE 1.8 M1 you need to enable the sysfs module which provides the IX and QX function blocks.

Cheers,
Alois

Dear Alois,

I compiled FORTE again on the Raspberry using the current version of FORTE from the git repository, now with enabled sysfs module.

Blinks like a charm now Very Happy

Very Happy

Just had to change the PARAM of the QX Block to 3 (this triggers the Raspberry GPIO Pin 5).

index.php/fa/25111/0/

index.php/fa/25111/0/

So wiringPi is not necessary anymore?

Thanks for the help Smile

Dear Max,

great. Yes we completely dropped wiringPi this allowed us to use the same code for raspberrypi and beaglbone GPIOs.

I have a similar problem when I try to compile the raspberry pi to use the GPIO

when I compile with default variables of the makefile everything it compile properly, but if I try to compile activating gpio generates errors :

Hi,

the default GPIOs for RaspberryPI is the module "sysfs" as described above.

I have the same problem Maximilian Hauske ,my blocks do not allow you to see the value of variables:

index.php/fa/25149/0/

index.php/fa/25149/0/

i used "sudo ./forte" and i enabled sysfs module.

Someone knows why this happens ?

Hi,

it looks like you have monitoring not enabled for your system. You can do this either by right clicking on the system in the system explorer or clicking on the arrow beside the magnifiyng glass in the toolbar. In the upcoming 1.8. M2 release there will also be a dedicated menu for monitoring.
You can see if your system has monitoring enabled with a green circle in the upper left corner of the system icon.

Cheers,
Alois

P.S.: sometimes you get the same N/A result although you have monitoring enabled. This is a known issue which we could currently not track down. The workaround is to disable and enable again the monitoring.

I can not get the value of the GPIO pins change from QX function.
I have done everything discussed in the forum:

- compile forte with sysfs module
- Run with sudo or sudo su
- Remote run from windows to raspberry pi
-installed wiringPi(blink example work correctly)

the electronic circuit works correctly if the LED runs from the Linux shell it works perfectly.

I am not sure about it, but I think the wiringPi is not used anymore (as said some post before). You should use just the sysFs module, and what I see is that you are trying to control the gpio22 directly in your ssh connection, but in your FB tester your parameter is 3. If this was the same test, I think you should use 22 as parameter to control your gpio22. Take in account too that a true value to the QX will put a 0 in the gpioXX/value file and viceversa, as discussed in other topic.

hi,
it seems that your output was not initialized correctly. I guess you set the parameters after the INIT event.
So please try first to set the QI = TRUE, PARAM = 3 and then click the INIT event.
If the STATUS = OK then you can set the OUT parameter and click the REQ event.

hi the problem is that you can only monitor FBs which are mapped to a FORTE device. The FBs you've selected are FBs mapped to FBRT from Holobloc which does not support our monitoring protocol.

Hello,

I am trying the same but my problem seems to that FB QX does not seems to be initialized. I have checked that sysfs is installed. When I download my application to FORTE, there is no unsupported object error as well. Can you tell where the problem might be?

I am also attaching my FORTE download log.

Can you try the same application but without the connection E_SR -> QX.REQ? Because the error you are getting is due to some initialization error. Unfortunately we cannot see the initialization error since the error is overwritten in STATUS(). Taking the connection away, will show the error that's happening in the initialization

Thanks, Jose. I have done as you advised. Status of QX FB is "OK" now but all the IOs of QX are static. All other FBs are working as intended i.e. E_SR->Q is fluctuating between true and false after every 500 ms but it seems that the effect is not carried on to QX FB.

Good to read that! The connection E_SR.EO->QX.REQ is the one that actually tells the hardware to turn on/off, that's why when you deleted it didn't show on the LED. Still, I'm not sure why it didn't work the first time. Maybe the initialization failed for some reason

Hello members!
I follow this link: "https://www.eclipse.org/4diac/documentation/html/installation/raspi.html"
While building forte for Rasberrypi3 model B I following step mentioned in Building FORTE on the RPI-> Preparing then 2)Building .
While building forte on rasberrypi, after running "make", two warning appears
1) Warning: the program should also define "void operator delete[](void*, std::size_t)"
2) Waring: conversion to 'TfroteFloat {aka float}' from 'CIEC_DWORD::TValueType {aka unsigned int}' may alter value. At "if ( CIEC_DWORD::scm_nMaxVal < pa_roVal) {

However, forte exe has been genrated after these two warning multiple time in b"in/posix/src directory".
Now I using 4DIAC IDE 1.8.4, on win7 after installation of jdk 1.8.
I write blink test program in 4DIAC, it do everything fine, and output is exactly like mentioned in attachments of first post of Awais Tanveer: message #1770065.

Please note that i didnot complete cross compilation steps. I just run forte exe on rasberrypi, then using 4DIAC, download blink test program on rasberrypi.local:61499.

Please guide! urgent response please.

Hi,

you can ignore the two warnings. The first one was already fixed in the development version and the second should not affect you.

Could you also show what the output values of your QX FB are. Are you running forte as root or does the user running forte has read/write access to the folders and files in the sysfs directory?

Thanks Sir! again for your prompt response. Issue has been resolved. There was issue because of misunderstanding of GPIOs Pins. GPIO Pin 3 points to PIN 5 on Raspberry PI 3 Model B. So when I connected LED between 5 and 6 Pin, it start blinking. Thanks again Sir!!!

I have similar problem when running the toggle with QX.

I compiled forte from git on an Orangepi zero plus with SysFs included. I run forte as root and get the following console putput:

root@orangepizeroplus2:~# ./forte
INFO: T#00ms: FORTE is up and running
INFO: T#00ms: Using default bootfile location: forte.fboot
INFO: T#00ms: Boot file forte.fboot opened
INFO: T#03ms: Bootfile correctly loaded
INFO: T#03ms: Closing bootfile
INFO: T#03ms: CBSDSocketInterface: Opening TCP-Server connection at: localhost:61499
INFO: T#03ms: 1
INFO: T#01005ms: 3out

Monitoring works fine and I see the toggle every 5s but the led on gpio3 between pin 5 and 6 is on but not toggling.

Something is wrong. Any hints.

kind regards

I solved it.

It was a mix of causes that led to headache.

Just to write it down here. If you use orange pi with allwinner cpu the gpio3 is not on the raspberry pin 5. If you play with pin 5 you have to address gpio11.

With 11 in the params of the QX, everything works perfect. The FB exports and unexports the pin and makes perfect use of it.

best regards, Frank
