Jeti Hall RPM-Sensor for 5€?

Very possible!

Totally overhauled the Jeti Hall RPM-Sensor today, a lot of new features

Hello Tero,
when compiling your code in Arduino IDE I constantly get this error:

\Data\MCProg\Arduino\libraries\JETI_EX_SENSOR\JETI_EX_SENSOR.cpp: In member function 'void JETI_Box_class::setValueBig(uint8_t, unsigned int*)':
\Data\MCProg\Arduino\libraries\JETI_EX_SENSOR\JETI_EX_SENSOR.cpp:89:16: error: invalid conversion from 'unsigned int*' to 'int*' [-fpermissive]
valueEX[ident]=(unsigned int*)valuebig;
^

Thanks for help!

You are using old version of JETI_EX_SENSOR library, it has no function setValueBig. You can download the correct libraries from my github github.com/RC-Thoughts/Jeti_Hall_RPM or from here:

Jeti Hall RPM-Sensor is updated with Jetibox monitoring

I build one and get all the time different values from the Sensor. But I guess all few seconds the right value is shown. I only use one one magnet and did not set up anything. Also if the engine is not running the on the DS-16 the "-" in the RPM Field comes and disappears any 2-3 seconds. Is this normal? Checked all cables and so on twice.

I used the ready compiled version of the sensor code, a original Arduino and a DC-16 with newest firmware. Receiver is a R9 EX

What do I wrong?

Thx Ingo
