Summary of change:
---- 5-8-2005 Current plans are to get the Genboard 3.3 running, and then make a new board to match the CBR600 application. The goal is to fit it in a very small case, use SMT components almost everywhere. Injectors are high Z, and this setup uses the stock Denso COP coils. I would like to keep: 4 injector channels 4 ignition channels 2 VR channels For other analog inputs, MAP, TPS, CTS and IAT will likely be all that remains. Maybe wideband 02 with permission. Ultimately, I might steal the PWM output (OC0) to control an electric water pump, since the injectors don't need it. Digikey has some nice parts for power switching: IRGS14C4DL-- 430V clamping, logic level IGBT. D2pak. IPS0315-- Smart FET, 12A, 50V clamp. Seems like it includes a driver, can I drop the 33151 and drive directly? (must be sure to change to non inverting) Also, is the flyback necessary? It claims that it can handle demag of "most" things. Might put in high voltage flyback to reduce noise on ground. General question-- Where is the zero crossing with VR, the center of the tooth and gap, or the edge of the tooth? ---- 4-8-2005 I got the VEMS wired and talking on the serial port. Seems like it had the bootloader installed already, but not the rest of the firmware. This took a while to figure out how to solve... ----
