E ma ti dirò... ho provato col led 13 e funziona... peso sia più un banale problema del circuito... il problema me lo presenta soltanto se collego un led esterno alla breadboard, per esempio al pin 4 come ho fatto io.

Print the number first and then print a % sign. What is wrong with that

If you print 100%, then 99%, the display shows 99%%.

There are several ways to solve the problem. Using sprintf() for formulate the string with a fixed number of cha...

Non credo che però verrà pubblicata una 1.0.6.
Queste modifiche forse entreranno nelle future versioni 1.5.x o 1.6.x.

well if cm2= 160 and cm1 = 100, because 160>100, it will activate the mode 2, and the servo will normally turn right? no? And yes, I ve forgot to introduce the cm1 == cm2 ...

Re: Filtro di Kalman e IMU.

il filtro Kallmann permette di pulire le uscite dei sensori dal rumore, ma poi ti serve un algoritmo di "sensor fusion" che faccia la fusione delle letture per darti l'output.

Io non ho mai lavorato col kallmann, uso la DCM (direct-cosine-matrix, un pò...

Well I was hoping someone was going to tell me what you need to know to work the problem out?

Sì, è un ARM.

Si parla di un micro Nordic con core ARM Cortex-M0 a 32 bit.

Well I started using char arrays, but it added gobbly gook in my string characters for some bizarre reason. the string seemed to be cleaner. I will try the chars again, see if a different approach can help.

BTW is it possible to create an open sized ch...

Ok, but when the onboard is supposed to perform the erase operation ? When it detects the upload of a sketch ?

What do you mean by "not an official board" ? In my case, it's exactly the same that here: http://arduino.cc/en/Guide/ArduinoDue .

Re: Scaling and outputing data to a LCD

Posted: 05 Jun 2013 01:51 AM PDT

You should only need to pre-define the 10 digits you need to dispay (0-9) and then convert the ADC reading (0-100) to separate digits and bit bang them to the display. To scale the 0-1023 value from the ADC to 0-100 use the [url=http://arduino.cc/en/R...

Re: SoftwareSerial dropping bytes when Arduino doing nRF24L01 radio.write()

Posted: 05 Jun 2013 01:48 AM PDT

I have something maybe similar, reading a basic serial out of an imp. It gets all the individual bytes, but stops adding it to a string at random places, when I try to add them all back up.
