\n \nCFE18 stands for "Can Bus Function Extension" or colloquially also "Can Switch Board" - why is this module needed? \n \nCan bus connections in vehicles sometimes pose major challenges for our customers. This is particularly true for motorsport applications, when electronics have to be housed in the steering wheel and then information from adjustment knobs (trimpots) or push buttons has to be transmitted via Can bus. \n \nCANchecked now offers a small additional module that has 17 inputs: 8 for switches (low side) and 9 for analog inputs (0-5V signal). A voltage converter to ensure connection to a 12V vehicle electrical system is also already integrated. \n \nIn the v2 (board v0.8) 3 switching outputs have also been added (low side max 0.5A) \n \nTested with: \n- MaxxECU \n- Ecumaster (EMUB and PMU) \n- LinkECU \n- Haltech (emulates an IO Expander A + B or just B) \n- Emtron \n \nThis device is also available with a housing:  CFE18 - can switch board \n \n

- The CFE18 hardware -

\n \n
\n \nWith only 29x27mm, the board is kept very compact and can be placed anywhere. The pin spacing is 2.54mm - for the power supply, for safety reasons, 3.81mm. \n \nWe have made a hole for fastening, which can be used as a screw connection. \n \n

CFE18 - Can Bus Termination

\n
\n \nA solder jumper is attached to the circuit board. \n \nIf you close this, the Can Bus termination with 120 Ohm is active. The solder jumper is OPEN by default . \n \n

One application would be a motorsport steering wheel.  With just 4 connections via a curly cord (12v, Ground, CANH and CANL) a wide variety of inputs can be transmitted via Can Bus.

Trim pots, momentary buttons and latching buttons.

\n \n*From hardware v0.8 \n \nThe CFE18 has three digital outputs starting with hardware version 0.8. These can handle a maximum load of 500mA and switch to ground (LOW SIDE). \n \nTo do this, send a CAN bus frame every 100ms (CAN ID is configurable here - if there is a pause of 500ms between frames, the timeout is activated and the outputs are deactivated): \n(0=inactive, 1=active) \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n

\n \n* From software version 3 \n \nIf the analog inputs fluctuate too much, they can be smoothed using software. This can be configured separately for each analog input. \n \nThe analog inputs are evaluated with each transmission (default: 20Hz). \n

\nIf, for example, a smoothing factor of 4 is set, the average of the last 16 measurements is taken. This makes the value quieter (smoother), but also reacts more slowly to fluctuations. Here you have to find a healthy middle ground to suit your sensors and application. \n \nThe setting is made via Can Bus - see " Configuration options " \n \n
