My open source Wideband Controller, SLC Free
Posted: Thu Apr 04, 2013 7:41 am
I have decided to release an open source version of my SLC commercial products, 50% to for publicity the other 50% because I want to give back to the open source community. SLC Free is the name of the open sourced wideband controller.
This is the first spin of the hardware, and things are working fine.
I plan on getting my design published in electronics magazine, so firmware and PCB files will be available once my article is published.
The design is based on the Cypress PSOC Cy8C24423; 4k flash, 0.256k RAM. All the external peripherals that other wideband controllers use; DACs, filters, instrumentation amplifier, voltage references, as all built inside the PSOC microcontroller using programmable digital and analog blocks. The only external non passive components is the NFET for switching the heater and the 5v regulator.
I expect that one can build the controller for around $10 provided you have a PSOC programmer which is ~ $30 on digikey.
The design will support the Bosch 4.9 LSU.
