then have a script to generate config.h from the file as part of the build process. This is exactly the job of the Java-tool, just with a graphic interface. Perhaps we should add the possibility to write the settings to a file and read it in again, to avoid to edit all the individual settings again...

That works ok now, I find I can trigger the code at virtually every attempt. Great! Thank you for testing! Ended up using a snapshot version of their executable. Does that mean the linked release did not work for you?! Fiddling around with the settings now trying to get the motor to turn! I'm using...

But let's see if Stancecoke or others are able to help and improve on this. So we should clean up the github repository and focus on one tutorial. My suggestion: 1. Delete all branches except the master and the feature/offroad 5 Step 2. Set all tutorial links (in our signatures and in the first pos...

Yes! you're right. I'm using SDCC 3.6.0. I can't seem to find a windows SDCC 3.7.0... Please read the tutorial , there you will find the link to the precompiled windows files and the instruction how to install them. SDCC 3.7.0 is only available for 64bit systems with windows. regards stancecoke

Hmm, it would be interesting, which tutorial the recent users were following and where problems occured. If you follow this chapter for chapter, there should be no problem! As written before: If there's a bug in the OSEC_Parameter_Configurator.jar , please report it, then I'll fix it. But you are ri...

I've commented out the print commands now, please try again. If this doesn't work, I can't do any more, as I have no LCD3...
But even if this works, the power cut at the speed limit is not implemented in casainhos code yet. So the offroad mode will only work with P3=0.

Sad to read, that you want to quit this project.... :( I think there's no problem with the Java Tool, it makes the firmware usable for people who don't have computer skills like you or me :-) If there's a bug in the Java Tool, I can fix it easily. But for this we need the feedback of the users. I th...

Commenting a line in ebike_app.c works with OSEC parameter configurator. But I want the slightly higher configurability of the firmware configurator tool. Can I use OSEC configurator and edit config.h then use the .bat file? please post the output of the cmd window, so we can see what's going wrong...

Sometimes the wheel starts to rotate itself without pressing the throttle. Two possibilities: 1. turn the throttle slightly while switching on the system, then release it after a few seconds 2. Put a small offset to the variable ui8_adc_throttle_offset in the adc.c, as you did it for the battery cu...

I thought the problem with the released throttle was solved?! Please upload your config.h again!

for the improvement of the commutation implementation it is useful to have a look at the code of the VESC perhaps. I had a short look at it, but I think it would take some days to understand the firmware structure. - Sensored and sensorless FOC wich auto-detection of all motor parameters is implemen...

You have to "morse" in the same way as in the video, one second for each step. You can change the duration for each step in the main.h The value is in 0.1s steps, "10" means one second. #define OFFROAD_TIME_1 10 //duration of first pull of break lever #define OFFROAD_TIME_2 10 //duration of first re...

And maybe you can try finish the feature, by adding the feedback to user. I've added a confirmation signal now. The display shows something about 80 km/h for three seconds, if the morse code was correct. The shown velocity differs due to the chosen wheel circumference, but I think that doesn't matt...

I've tested it on the workbench now. It works
I've added print commands to each step temporaribly to show the progress at the screen.
If the speed limit is really disabled on a real ride is not tested yet...

I've pushed the 5-step-version to a new branch now. https://github.com/OpenSource-EBike-firmware/BMSBattery_S_controllers_firmware/tree/feature/offroad_mode_5_step I left the initial values for the step-durations at one second. The tolerance is now settable in the main.h. It is set to 0.8s now. You ...

So, we can make the duration of 5 steps and the tolerance user-settable.

regards
stancecoke

Hm, but then we can keep the three steps, that's diffcult enough to hit....
Or we take more steps, but increase the tolerance, it's half a second recently.

regards
stancecoke

Do you want to implement that Stancecoke? If so, please try using the switch case as is better to understand than a big number of ifs. In this case, with no individual durations of the morse code, there is no need for a switch case, it's just counting up one variable in one if-structure... But as g...

Why not 5 really fast clicks on the lever,

Good idea! Very easy to program. But you will loose the possibility to define you own individual morse-code...
Is anyone seriously interested in using it in this way?

regards
stancecoke

Hm, I would prefer to activate the offroad mode while riding, without the need of switching off/on the system.
As feedback for the user, we could set the speed-display to 99km/h for three seconds e.g.

regards
stancecoke

Hm, that's not my prefered solution, as you have to stop, swtich off, switch on try to morse, fail, switch off, switch on, try again..... It is quite difficult to find the right rythm and I see no danger to activate the offroad-mode randomly... But no problem, it's easy for me to modify it in the wa...

I see. I implemented thinking that user can do it only once when system boots up. Hmm, still you have no chance for a second try or to put in the code after first braking. You have to switch off/on the system each time, for a new try :-( Why do you use all the constants?! The simple numbering was m...

You are right. I just changed that, please review now. Hm, with OFFROAD_STATE_END 4, you will disable the routine with the first time you are using the brake lever. You have to reset the state to zero, if you are just using the break lever for breaking, or if you failed to find the right rythm of t...

The code is untested as now I don't have have ready hardware to test it. Hm, I don't understand your code, I think it can't work. The if condition will never get true, so the switch structure will never be called.... if (ui8_offroad_state == 3) Another bug in my code: the 25 has to be 5. The 25 rep...

But the cut in speed is kind of fast, may be ok for max erps but not for user speed limit. Anyway, we can start like that for now. Yes, I think we should ramp down the power slowly within a range of 2 km/h. It's solved that way in the "Forumscontroller" and in my fork. But it has to be placed in th...
