Which C compiler/debugger IDE are you using?

Currently I am using Codeblocks but unfortunately It does not seem to support LXTerminal when debugging so I can't see printf etc on console.

I would like another IDE but I need the debugger. Geany does not have one.

I've read many "Read this first" and FAQ type -posts here concerning problems getting UART/SPI etc work. Judging from lengthy and ongoing discussion appears that some solutions work for some for some of the time etc.. All sort of myriad settings are applied to some success on some models. ...

I don't have a Itead SIM800, but looking at the link to it you provided, it connects to the Pi 3B via the GPIO pins, which means it uses the Pi's serial port. Wvdialconfig reports it as "/dev/ttyS0" so I put that value in minicom ("sudo minicom -s") and tested it. This indicates...

How do I enable it back on without rebooting whole system? My goal is to "soft boot" the modem driver (or something) if possible if it goes into non-responsive mode. You could try with a simple device like an USB key (mass storage). Your device should detach properly once the path is rele...

Perhaps you can do something like "echo 1 > /sys/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.XXX/remove" to "unplug" the device? (the 1-1/1-1.X part varies according to the way your device is connected to the Pi, you'll have to discover the path in sysfs that depicts your dev...

A workaround for dealing with changing USB? naming is that you have a small C program that does a and then you open the "/whatever/some.txt" file and parse what usb is used for what and apply that for the rest of your program.

I tried another modem (a shield), this time an Itead SIM800 (picture here: https://www.itead.cc/wiki/RASPBERRY_PI_SIM800_GSM/GPRS_ADD-ON) Wvdialconfig reports it as "/dev/ttyS0" so I put that value in minicom ("sudo minicom -s") and tested it. Minicom VT102 goes crazy posting a l...

I am using minicom and other programs to test sending an sms message from an RPi 3. I connect an old Nokia Symbian phone to the USB port. I enter the right sequence of AT command.. After I issue the last AT command AT+CMGS="+0123456789" <ENTER> and then send my message ending to CTRL+Z. I ...

My Rpi has multiple USB devices (keyboard, camera etc.).
I am designing a program (C) that should know when the phene is connected and what is the handle I can use to send sms messages.

I'd like to design my own case for my project. My cases need to be double the size lengthwise to have room for numpad and/or other stuff. So probably I'd have to design with a 3d program (I use Blender) and have it 3d printed. What are my options? I don't have a 3d printer. What are approximate cost...

I have an addition question to OP. I tested the code shown in this forum post with an USB input device connected to an RPi3. Works fine when I use open("/dev/ttyACM0"..) etc.. I'd like to send and receive data from an old Nokia Symbian mobile phone I have connected to another USB port. The...

HAIP is too accurate - accuracy in this case can be +/-5 meters. What about RF inside the warehouse?

I did a quick look at GPS repeaters. It is not clear whether a repeter will just report its position and not the forklift withing the warehouse.

I need to get the whereabouts of forklift trucks during the day. GPS is great for that when they are outside. The problem I am having when the forklift goes inside a warehouse and the signal is lost. What kind of "backup gps" should be looking for while the forklift is parked inside and I ...
