TTL output signal from Freematics

Post by Davide4491 »

Is it possible to have an'output TTL signal from freematics.
For example if i have 3000 rpm i would like to have 50 hz (3000/60) signal between 0 to 5 volts.
I need to connect this signal in analyser in order to do some measure.
Thanks

You can output PWM signal with the adapter.

Hi thanks for the answer:

basically I need this:

The information will be read directly from the CAN-OBD2- interface (ISO 15765 CAN, 11/29 Bit ID, 250/500 kBaud).

The instrument has to be simply connected to the standard OBD2 connector and the RPM or speed is shown directly on the LCD display, but in addition I need also to output the data as an analog voltage signal (0-5 V) or as a digital pulse sequence (TTL).
because I need to analyse the signal in an analyser,could I have it in a simple way from freematics?

thanks a lot
