Gen Board/Under Development/Firm Ware/Next Release

This page specifies what needs to be done for the next firmware release.

Next release is named: STABLE_1_1

Tasks left before release:

New Timing Scheme (Dave & Marcell)
- complete the JAVA prototype
- implement the OnlineCourse/Modeling/Scheduler . This makes it possible to guarantee worstcase 300..400 usec turnaround for the highest priority trigger-process code
- Port model to firmware
- the interrupt becomes rediculously simple. This helps porting to ARM
- the clever stuff moves to userspace. If the next output event is due in less than 400usec (or there is no trigger expected before the output event), we schedule the eventqueue event right away (not wait for next trigger)
- Make it work
Scheduler (Fredrik)
- Framework needs review
- Port tasks to use it
Move towards 16x16 maps with configurable bins per table
- Implement in firmware
- Adapt megatune / mtx profiles to suit firmware changes
Remove config.warmup_rpm[] and add back a single rpm multiplier for decreasing warmup enrichment at increasing rpms
Make it bootable again
- The Problem
- Halfway through main_loop usercode stops running
- OCR16 (event2core) and ADC keeps on triggering
- So does PS2 whenever a key is pressed down
- It broke between 20041124 and 20041201
- any ideas?

Tasks suggested:

Make seperate v2 release and only support it for bugfixes
Sensor inputs
- Displaying and logging all inputs
  - EGT x 2
  - Exhaust backpressure
  - Fuel Pressure
  - Second WBO2 Channel
  - User configurable inputs for the free ADC Channels
- EGT based fuel enrichment (High power engines need a enrichment for cooling when the engine has been under load for a while
- Launch Control (Add a configurable revlimit to ALS code, fuelcut or configurable fuelcut/ignition cut)
- Make the temp sensors configurable, instead of compile time generated and converted tables (calibrate through ADC counts, 3 constants, eg. at 25 and 100 Celsius and 0Â° (melting ice)
- Alarms when lost or broken sensor signals detected
- Alarm when TPS is outside the configured range (with some mariginal), maybe add a 47k or so pullup so a lost signal can be identified (Currently floating)
- if possible, detect a broken MAP signal: the same method that we use for WBO2 nernst would work everywhere. It involves pulsing the signal through a big (10..100k) resistor from a 5V square pulsing and measuring the divided AC component. At high impedance (no signal connected) the AC component will be high.
If new scheduler and timing from last tooth takes a lot of time to finish, i think it would be wise to postpone them to a later release and try to support simple trigger + cam sync on the most common engines, 4,5,6 and 8 cyl even fire. (This is just a thought, we really need to get this working soon.)
