BME280 sensor BOB ordered. (Adafruit)

UK source http://skpang.co.uk/catalog/adafruit-bm ... -1447.html

Should be here for Friday, hopefully be able to test it at the weekend.

Hi

Downloaded on Friday evening, but just saved to the hard drive. Downloaded all ok. Not installed it yet though.

1.0 Introduction. The purpose of this project is to develop a simple method of monitoring both the temperature and mains supply status of a freezer located for example in an outhouse. It utilises the nRF24L01 RF transceiver to send the data between the remote sensor and main display located inside....

Hi Jan I too think I2C can be a difficult concept. Sometimes I can get something to work fairly easily and other times I can really struggle with the device. I bought a book on the subject from Elektor Mastering The I2C BUS by Vincent Himpe, it does cover everything from the basics to advanced topic...

Hi Sergio C was the original language. After that came C++ C++ is similar but has extra commands. A C++ compiler can compile to either C or C++, but A C compiler can only do standard C. C# was the next generation of compiler. I've never used it myself, but if you google it you will be able to find p...

Hi Sergioigel

Once you have developed your flowchart, you can compile to C, compile to hex or directly to the chip, which goes through both c and hex.

You will find these and other intermediate files in the folder you have saved the flowchart file in.

However It cannot compile to C#

Hi Kjell The fcpx files are the compiled components used in flowcode and cannot be read in the same was as for example a "C" source code file. You can look at the code using an editor such as UltraEdit (my choice), but all you will see us blocks of hex numbers. Changing the file will almost certainl...

Merry Christmas to all at Matrix, and on the forums

ARRRRRGGGGG

Happy Christmas Steve. The old ones are still the best

I've just assembled a nice little project, a simple frequency counter based on an ATMEGA 328P device. Its programmed using an Arduino Sketch. (The device comes pre-programmed). Source code can be downloaded from the Sparkfun website, and should be possible to rewrite in flowcode. Specified Maximum F...

That's it, all working.

Thanks Ben.

Hi Ben I'm now getting this error. Launching the programmer...

Hi Ben I've added your new components but I'm not able to get the board to program C:\Program Files (x86)\Matrix TSL\Flowcode V7\compilers\pic32\bin\xc32-gcc.exe reported error code 255 After pressing compile to chip the window goes blank and shows the above message I have reloaded the bootloader in...

Hi Docara As Ben points out, the EB091 (16Bit) board is very powerful but the device is fixed and cannot be changed. If you want to use 16bit and be able to change devices, try the EB064 board. Whereas the EB006 can program a wide range of 8bit devices from simple 8pin pics to the 40pin devices. If ...

A few months back Elektor did a feature on a range of development boards. There are a huge range of different types available now. 1 All using different types of processors 2 All using different development IDEs 3 All from different companies 4 To me the most important, they are mostly reasonably pr...

Hi QMESAR I have mainly used the Rasbian os for my Pi's, (not tried noobs). But the big advantage with the pi over conventional computers, is all you have to do is swop the SD card around to get another OS. I have several cards configured for different things, so its easy to try both debian and noob...

Looks interesting

They have a 4.3 inch e-paper display on Amazon of all places for just under £50. Bulk price from a wholesaler would drop that by quite a bit I expect.

Cool Components in the UK have a 2.7 inch for £33.00 (Non in stock ) Usable with Arduino or Raspberry Pi.

Hi mdism

Any flowcode licence allows you to load the software on your main PC and another pc owned by you, say your laptop, but a single licence only allows you to run one copy at a time.
If you want to run more than one copy at once you will need two or more licences.

RFID Card Entry Security System Introduction. This is a card entry security system using I-Code RFID Cards. I have a selection of 4 different card, each with different UIDs. Three of these have been programmed to be accepted by the system and the 4th is unrecognised and so will trigger the alarm I ...

Hi Flowcode isn't the only culprit that does this. It would be nice if software could do the housekeeping once installed though. I use a program called ccleaner, which for its basic version is free, I've used the pro version ($20) of it for a few years now and it works great for cleaning up the inte...

Hi saschech

If you are having problems with the new version of FC can you please report it here.
Matrix have a dedicated forum for problems with FC 7.1

viewtopic.php?f=64&t=18151

I must have had that board for a while then. Anything along those lines would be great, I can soon pick up another sensor.

Hi Ben One thing Id like to see in FC7 sometime ( please :D ) is an I2C atmospheric pressure sensor, along the lines of the Bosch BMP 085 (Adafruit make a break out board for it.) I've had one working on an Arduino using the Adafruit library, but not managed to get anywhere in FC yet. It could even ...

Hi Ben
FC7.1 Installed and activated all ok

I decided to uninstall 7.04, clean the registry and do a clean install on 7.1 as I had 2 versions of some components from the last release.

Hi Garry

I had a similar issue with FC7 this week
It was caused by having a micro USB converter (empty) plugged into the internal card reader.
Removing the adaptor (or having a memory card in the adaptor) and all was well.
