My plan is to make the RadioBoard to be real, look also VemsFrontier/Bluetooth
I got Volvo Amazon with B20.
What is currently working&tested firmware for older GenBoard/VerTwo?
- the latest tested for v2 is very old, around 2004.11.24
- Now I got v11 firmware working on GenBoard/VerTwo somehow, it wasn't using h[] for inj (on GenBoard/VerTwo), problem was secondary trigger. Maybe I'll table test STABLE1_0 with GenBoard/VerTwo. Also few lcd pages are blank with v11, but I'll get back to this (testing new firware on v2).
- I haven't used IAC with v2 but now I got bosch PWM controlled IAC in my hands. IAC takes ~1 amp, so L293 output (maybe 2 in parallel) would be good (should be fine, but make sure there is flyback diode and you disable stepper in config.stepper_conf) so digitalout(config.iac_sol_channel, output); is used to PWM theiac_sol_channel nicely.
- iac_conf=78 looks right for first glance, since:
- global.h uint8_t iac_conf; // iac, conf bit7:4:stepper msec, bit3:preciseidle(0=on/off) bit2:stepper(0=pwm) bit1:low_power_halt bit0:power_iac_only_when_move
- bit3=1 for config.iac_conf & _BV(precise_idle)
- bit2=0 config.iac_conf & _BV(stepper_iac)
- There already are flyback if they are assembled, but did you mean that upper diodes should go to FLYBACK instead of +12v (+12v could be and in this case its fused)? Or is 1N4007 speed an issue, maybe not, but faster would be better (on injector flyback too)? The onboard 1N4007 diodes to 12V should be fine. Connecting flyback diode's cathode directly to the + pin of the solenoid would be best, of course (maybe use shared fuse for board and the iac so least tweaking is needed: 1.5 .. 2.5A fuse should be perfect).
- digitalout in firmware is not fully implemented when compiled to GenBoard/VerTwo. However it seems very easy to switch on/OFF any output at the end of injector.c digitalout() function based on the value of "facility" and "valbit". (valbit most significant, 7th bit is ON/OFF).
- Yes, that was very easy, thanks!
