Re: Suggestion - disable Tool Tips

Before seeing this post this morning I found a checkbox flag in "Task Bar (Window List) Settings", but unchecking that and doing a re-login in did not kill the tool tips. On following through the edit above (thanks Paeryn for that, by the way) I found that the tooltips setting was '0' in /...

Re: "Click here..." is annoying

So, found it. If you right click on the task bar and open "Task Bar (Window List) Settings", there it is, right at the top. A check box to enable or disable the tool tips.
Except that it does not actually turn off the tool tips. They still keep coming.

Re: "Click here..." is annoying

Windoze10 - not a discussion I would get into. I decided some time ago that once Win7 was no longer viable I would become a Mac person, and that will probably happen this year. However in Win7 there is a flag to turn that off, and I would be surprised if there was not one somewhere in Win10.

Re: "Click here..." is annoying

Recompile a module to remove tool tips? Hmmmm. I must admit that my first thought is "and then they wonder why people don't convert to Linux".
I guess I will be tolerating the tips for the small amount I intend doing with Pi's.
Thanks for the info.

Suggestion - disable Tool Tips

Hi, I am looking at the Pi for some projects and have just loaded a Model 3B+ with Raspbian Buster. Just an observation - the tool tips are a real pain, and pretty much unnecessary for most people. However, there does not seem to be a way to disable them, and the best suggestion I have found is that...

Re: "Click here..." is annoying

I know this is an old thread but I currently have the same issue and this fix is not relevant any more. This line is no longer in this autostart file.
(Raspbian Buster, latest version as at this date, fully updated.)

Re: Asking for help with magnet (reed) switch

All the same, perhaps you put at least something for limiting. Even a few 10's of ohms.

Re: Asking for help with magnet (reed) switch

It is a simply circuit and simple code, so must be something basic. Can you tell us what kind of LED is that? Normally forward volt drop is about 1.8V for a normal LED. Does it have an internal limiting resistor? Also, what is your power supply like and do you have anything else being powered by the...

Re: Asking for help with magnet (reed) switch

What is your circuit configuration? Depending on whether you connect the switch to GND or 3.3V, you will need a pull up or pull down respectively. Have you set the PUP or PDN property on the GPIO pin? Or have you connected an external resistor?

Re: raspberry pi and modbus rtu

The only difference between RS232 and RS485 is the electronics of the interface. The serial port on the Pi is operated the same way. In fact, 485 is easier than 232 - no handshake lines. The easiest way to get RS45 is probably a click board like http://www.mikroe.com/click/rs485-5v/. Also, if you ha...

Re: Probably a silly question

I run my all RPi's via VNC to my pc. What I did was to set up one RPi as a reference (using the keyboard, mouse, and monitor from my computer) with all the main setups, VNC, and software installed. Then I took the SD out and read an image from it. Now when I have a new RPi I copy that image file to ...

Re: Easiest programming language for controlling gpio pins

Hi Flatmax, I am also a total newbie to Pi, Linux etc. I started with RPi.GPIO, and it is easy to use and learn. I was going to attach a sample for you but the forum does not let me, so pasted in below.. Currently having a look at wiringPi - seems just as easy and documentation is better. But I woul...

Re: No PYTHONPATH or other environment variables

Hi Marcus, Was thinking about just bit-bangíng it, just a simple device so it would not be hard to get this working. But for my own edification and learning curve, I would like to do it right. Most of my background is embedded so have done that a lot. (For me, the RPi is a big step up :) . Is there ...

Re: No PYTHONPATH or other environment variables

Thanks again for the replies. @DirkS - The query about PYTHONPATH came about because I could not get my program to import rpi.gpio, and I had seen mention of this environment variable. Compiling using "python3" as suggested sorted that out. @croston - As I said above, I had already looked ...

Re: Python 3 and spidev

Thanks joan and B.Goode. I had used the typical noobe technique of using an off-a-web-command-list to install spidev using Python by default. So, a good lesson learnt for the future. Using Python3 to build and install did the trick.

Python 3 and spidev

Status - a newcomer to Linux and Raspberry Pi. Running fully updated Rasbian and was running Python 3. I installed spidev which went without any errors. However then when I wrote a basic framework to start checking how it all works, I could not get it to recognise spidev at the import statement. Aft...

No PYTHONPATH or other environment variables

So, total beginner for Linux, Raspberry, and Python so steep learning curve. But a lot of experience as embedded programmer to call on, so doing OK. I have the RasPi 3B, running Rasbian all updated etc. I am working with Python 3.4.2 which I believe is the latest issue and RPi.GPIO 0.6.2. As a start...
