..., but if all of a sudden an FBC compiler for the Raspberry Pi shows up, ...

Some are available ...

The Git version (1.01.0) is ready for boot-straping on RPi. dkl made a guide, which we fine tuned a bit. Now it runs fine on BBB / Debian and should work on RPi as well. (And there's a package for RPi from D. J. Peters, based on older sources.)

That is a log in session to my Raspberry Pi using the LAN, so maybe in place of a com port selection I enter an IP address, could I do it with the FBC compiler?

I log in to my BBB using ssh (either LAN or USB).

Below is updated code, now it compiles with the FBC 1.0 64-bit, not sure what will happen with a 32-bit version compile, hopefully nothing. I changed a few lines, and added some more com port selections, nothing major. If there is a problem, note it here and I will see what should be changed unless you are feeling good and you provide some updated code.

Somewhere along the line I will have to try to port FBC to the Raspberry Pi, the instructions in the WiKi looked very straight forward, but I have not done anything like that before. I have one Raspberry Pi B+ setup as my Linux desktop, so I may have to try an install of FBC on that unit.

I use Putty as my command line access to my Raspberry Pi from my Windows 7 desktop, I was just thinking, as a learning experiment, to see if I could add something like that to my FBterm.bas program. But, just thinking about it, it may be a little more than what I can do, not sure how SSH would be handled with the FBC.

So, I went ahead and installed FBC for the Raspberry Pi, luckily I found the binaries over in the Linux forum. I also installed Geany on my Raspberry Pi and on my Windows 7 desktop, I might as well start being consistent in my IDE programs.

The first problem that I ran into when trying to compile a simple .bas program was, -lncurses. I suggest, on the Raspberry Pi, doing a 'sudo apt-cache search ncurses', it comes up with a long list of files, but in there you should find a listing for 'libncursese5-dev'. The next step, of course, is 'sudo apt-get install libncurses5-dev', which should install the missing -lncurses. Since I use 'fbc -s gui xxxx.bas' for my Windows 7 compile, will 'fbc -s gui xxxx.bas' work on the Raspberry Pi, or do I have to install more missing libs? And of course, what would be the preferred GUI solution for a .bas program on the RPi?

As a trial run, I have another program called SimTerm.bas which I went ahead and compiled using Geany, on the Raspberry Pi, which worked after adding the missing lib. On my test hardware setup I have an XBee module plugged into the RPi USB port(/dev/ttyUSB0) and another XBee module plugged into my Windows 7 desktop. I started my FBterm.bas program on the Windows desktop, and I started SimTerm.bas on the RPi, and they were communicating as expected. On the RPi and on the Linux installs I think you have to setup some dialout privileges in order to get access to the /dev/ttyXXXX ports, but I am not sure if FBC does that for you when you compile a program that uses the tty ports.

Now I will be porting my FBterm.bas program to the RPi and see if I run into any problems.

Option -s gui has no effect on LINUX systems,

The prefered GUI solution is always GTK+ (on all systems, including RPi).

On the RPi and on the Linux installs I think you have to setup some dialout privileges in order to get access to the /dev/ttyXXXX ports, but I am not sure if FBC does that for you when you compile a program that uses the tty ports.

Usually the user has to be a member of the 'dialout' group to access /dev/ttyXXXX (this may vary in different LINUX ports).

I don't understand what you're trying to do.

To control the RPi from your PC, connect the RPi to your LAN and just execute ssh username@RPi_IP_Addr at the commanmd line of your PC. You'll get a login prompt from the RPi. After login you'll have command line access on the RPi.

On a LINUX PC you can use ssh -X username@RPi_IP_Addr and you can run grafic applications as well. (I don't know if there's a similar ssh option on other OSs as well.)

I don't understand what you're trying to do.

This is just a test run to see how my serial terminal programs would work. It was easier for me to just hook up an XBee module on each computer as opposed to creating a null modem cable to connect between the computers. Now that I am satisfied with the FB terminal program on the RPi, now I will start to develop a project using the RPi and have an XBee installed as a redundant backup that could be used if I move the unit to an area where I do not have a LAN hookup. I also have a WiFi module that I use, but I did notice there are dead spots where the WiFi gets no reception, hence the XBee backup.

I do want to make note that working with the FB serial is much easier, and in my opinion, much better than trying to do it using Python serial or C for that matter.

Not trying to derail my own thread, but on the RPi I had a Sensirion sht11 module working with a C program, that was available for the RPi. I guess my question is, is there such a program written in FB, or is there a way of using some of the C code within FB to have FB access the RPi GPIO to get readings from the sht11 module? I did do a search for sht11 on this forum and got one hit, but there was no relevant code that I could look at. If I get some information that leads me to believe that it possible to do this with freeBASIC, then I will start a thread of its own to describe my adventure into all this, as to how this could be done using freeBASIC.

[dasyar]

To get back on topic, I just tried to compile FBterm.bas on my Raspberry Pi, and I get the following: cannot find -IX11, IXext, IXpm, IXrandr, IXrender. Not sure what this means, I thought the Raspberry Pi had an X11 system installed, or is this pertaining to something different?

[dkl]

Perhaps the development libraries for X11 are not installed. On many Linux distros they are separate from the main X11 packages (e.g. libx11 vs libx11-dev) because they're not needed by "normal" users (only developers).

[dasyar]

After installing libx11-dev, now I get the following: cannot find -IXext, IXpm, IXrandr, IXrender. Took care of one item, not sure how to get the rest.

[dkl]

libx11-dev libxext-dev libxrender-dev libxrandr-dev libxpm-dev

[dasyar]

Thanks dkl for the nudge in the right direction. I did another compile, and all went well. Now I need some suggestions as to how to keep just one source code file that will compile for Windows or Linux or Raspberry Pi or whatever. The other thing that becomes inconsistent is my selection bar (port and baud), for Windows it is COMxx:, which I allocated the correct space. Now for the Linux/Raspberry Pi stuff I have /dev/ttyUSBx: or /dev/ttyxx: or /dev'ttyAMA0. Is there a way to have a specific selection bar for a Windows compile and a specific selection bar for a Linux compile all within the same program. This is starting to look like some very complex programming code, if there even is a way to do it.

[dkl]

For example: #ifdef __FB_WIN32__ ... #else ... #endif

[dasyar]

I just did a test run using #ifdef __FB_WIN64__ ... #else ... #endif, since I have FBC 64-bit installed, did not work correctly. When I changed it too WIN32, then it worked correctly. So, I take it that WIN32 covers the FBC 64-bit version? Will this be the consistent form or will there be specific WIN32 and WIN64 declarations down the road at some point?

[dkl]

That's right, __FB_WIN32__ refers to Windows as a whole, both 32bit and 64bit, much like the _WIN32 predefine used by Windows C compilers. But we have an additional __FB_64BIT__ define which allows Win32 and Win64 to be distinguished.

Code: Select all

#ifdef __FB_WIN32__
   #print "Windows"
#elseif defined(__FB_LINUX__)
   #print "Linux"
#endif

#ifdef __FB_ARM__
   #ifdef __FB_64BIT__
      #print "64bit, AArch64"
   #else
      #print "32bit, ARM"
   #endif
#else
   #ifdef __FB_64BIT__
      #print "64bit, x86_64"
   #else
      #print "32bit, x86"
   #endif
#endif

[dasyar]

I did some more changes to FBterm.bas, now the single code file compiles on Windows 7 PC and the Raspberry Pi. Since I do not have a "real" Linux box available, I could not test it there. I think I got all the bugs, but ...

Not sure if everybody knows, but for the Raspberry Pi, you only have miniterm as a choice, and in my opinion, it was an awkward piece of software to use. So I hope FBterm is a little bit better, and maybe easier to use. One of these days I might try to get a workable FBterm on a PC-BSD box, but am not sure if FBC is available for it. Now I am not sure what else can be done with FBterm, not even sure if anybody else is using it. Any problems with the program, like a bug, let me know here.

[ThisPlaceHere]

I copied your code for a quick test of some serial connections.. but it didn't work as well I had hoped, so I spent some time making a few [okay, a lot of] changes to get things to work as I expected. I'm posting what I ended up with in case you want to take a look at some of the changes or corrections. I just went back in filled in notes up top by the revision comments so you can pinpoint my "few" changes.
I tried to preserve the original design as much as possible, but sometimes I get carried away making things they way I see fit.
Tested on FreeDos, Windows 2000, and Windows 7; and using RS485 for long distance between devices.

Code: Select all

' FBterm.bas
' FBterm.exe - Windows
' FBterm.exe - Windows
' August 2, 2011
' Version 2.0 revision 02
' Oct 9, 2014
' Version 2.0 revision 03
'   - Fixed code to run with 64-bit FBC
'   - Lines 33,34,35 changed, using {}
' Oct 17, 2014
' Version 2.0 revision 04
'   - Code adjustments for compiling Linux version
'   - Ajustments for Linux screen
'   - Works for Raspberry Pi

' Version ?something_new_if_you_so_choose_to_use_it?
' Fixed these items:
'   - no original color defined
'   - removed local line feed for each port read
'   - if echo is off, no more LF with CR
'   - changed variable named echo to be it's own setting, and to remember setting between modes
'   - origcolor routine removed - used direct Color instead
'   - fixed color change with echo setting change
'   - removed cursor setting since we're doing it manually
'   - shortened the cursor blinking routine
'   - fixed scrolling of screen with every cursor blink when at bottom of screen
'   - changed numtosend to integer to handle overflows
'   - fixed jumps (goto statements) to not cause multiple instances of Loops
'   - combined all mouse box tests into a single button press test
'       to shorten code, and allow easy way to keep from multi-clicking
'   - removed unused variables
'   - re-worked the send number function. Was not sending all numbers entered!
'   - changed send number to check for allowable range (0 to 255)
'       also changed local echo to show numbers (characters) less than 32 as the
'       number instead of the trying to execute the character. They will be shown
'       in a reverse-type (red background)
'   - sendnum() input line set to always be on empty line
'   - a few other changes to make sure echo off was indeed echo off
