Hello everybody,
there will be a free/open source version of this controller too. We named it BL49sp and comparing to the BL49 there is no onboard CAN. It is a small single pcb with 25x60 mm for stand-alone operation or 25x35 mm without the power supply for using it as a add-in controller. To use it as a add-in you can cut off two sides of the pcb to make it smaller if you want. Transferring the measurement to the Speeduino or any other ECU is possible via analog signal (DAC) or serial interface (TTL). There is also a PWM out to simulate a narrowband 0-1V signal or to connect one of these cheap chinese 52mm gauges with LED ring and digital display (13$ on ebay)
The development of the hardware should be finished soon and after building the first prototype i will try to adapt the nano lambda code from Alfagta to this hardware ( https://github.com/TurboCorse/LambdaCtrl )
I was also trying to convert the code to Arduino IDE. The code compiles, but this is absolutely untested at the moment.
As tooly already posted the link to github you can find any progress on this project on https://github.com/oelprinz-org/BL49SP . Any thoughts, requests or improvements are welcome
Best regards,
Chris
