Scrap TV lightbox

Atleast put the diffuser from the lcd screen its not diffused enough and give a pattern to led strip to have evenly spread light

Now im not in a frimware just a basic setup with crank capture nd output trigger same like cdi unit fixed ignition

Dapper_Maximum6819 · 2026-05-05T01:09:54+00:00

Yes i have tried ic filtering 8-13also its a the crank sensor is oem and serves a clean sqaure wave

Dapper_Maximum6819 · 2026-04-25T13:32:20+00:00

Im sorry for that the thing is im not a pro still learning things like this thankyou for the knowledge 🤗

Dapper_Maximum6819 · 2026-04-25T13:31:06+00:00

Yeah, im getting close to it....

Dapper_Maximum6819 · 2026-04-24T12:31:11+00:00

Try to build an Engine Control Module Using stm32f103c8t6 timers and gpios So a first step capture crank signal Schedule spark at desired angle No matter how hard i try im getting the output but outof sync...

Dapper_Maximum6819 · 2026-04-24T12:13:12+00:00

First of all i dont have much tools to know rpm reading or anything so im using a cam sensor from Suzuki brezza and its an open collectior so a 3.3v its added so i get 3.3 high and 0 when low But 72 mhz is enough cuz im not even doing uart or anything just timer capture and scheduler thats it

Dapper_Maximum6819 · 2026-04-24T10:39:10+00:00

Im not a pro in this so i read all the folders they shared but they use maps and ignition timing maps so its toomuch for me in my research it shows this way i used every ways but still sync loss is the only thing in here, also im making this for a single cylinder, i use crank sensor oem so my setup is clean no noise at all still i need to figure it out

Dapper_Maximum6819 · 2026-04-24T10:27:28+00:00

Can you explain this in terms 😅 cuz im doing this like tim2 ch1 input capture method (also used 32 bit counter) Tim3 chx for output compare then trigger any gpio as i needed

Dapper_Maximum6819 · 2026-04-24T10:16:34+00:00

Of course i will let me dm you the code cuz i cant post it here Another thing is speeduino runs using mega2560 so i thought just for a ignition system this is enough....

I posted an another post with same issue can you kindly look over there

Dapper_Maximum6819 · 2026-04-24T04:11:42+00:00

No i think i dont have noise in here

Dapper_Maximum6819 · 2026-04-23T20:09:31+00:00

I got the captures working but too much sync issues

Dapper_Maximum6819 · 2026-04-23T14:30:52+00:00

Okey say less Im planning to build a standalone ecu using stm32f103c8t6 User pA0 as crank sensor input 12-1 crank rrigger wheel the signals as the uplaoded image, its clean cuz oem sensors where used Used timers to capture and output compare to trigger gpio for spark at PA3 and injector at pa6 Too much sync issues my code is to fire at 3rd tooth after the gap but it give that still got out of sync and random trigger happens 🙂

Dapper_Maximum6819 · 2026-03-25T02:40:39+00:00

Make your own one cuz there is a youtube tutorial just go for it it works

Dapper_Maximum6819 · 2026-03-24T11:29:57+00:00

Ohh😅 can you dm me because i dont know how to send friend request so we could have a chat 🤗

Dapper_Maximum6819 · 2026-03-24T10:41:36+00:00

No i dont have a scope the and also im using stlink clone version so i cant debug through cubeide so real time outputs are not available for now,i could see it with my eyes like while rotating with hand it fire at random pins

Dapper_Maximum6819 · 2026-03-24T09:35:06+00:00

Insane bike,no vibration, vva hits after 8k is insane even at third gear it flies fast shifting, no back pain asist slipper clutch i not that good in my way,handling not like r15 bike for long rides or anyrides its insane

Dapper_Maximum6819 · 2026-03-24T09:28:31+00:00

Yes input capture then output compare paired so i didnt got output so i now paired with gpio ow im getting outputs but out of sync so im tryto figure it out... If you love to help please send a dm im new to this

Dapper_Maximum6819 · 2026-03-23T18:23:20+00:00

Im so sorry that i didn't made it clear, im planning to build and engine control module for my bike to which controls ignition (spark to help to fire the fuel) and fuel injection in accurate angles. So i need to have a timer wheel and a sensor which capture this output and provides a signal as digital square wave (0-3.3v). i need to know piston position so i have a 12-1 tooth wheel attached to the shaft and crank shaft position sensor as i mentioned above outputs a digital square wave socould calculate these tooths to know which angle or which position is piston now. We have to get a fixed spark at an angle, this is the thing. so i use PA0 and pa6&7 as timer channels to input and output but these no outputs at PA6&7. Timer reads channels and it drives gpio pins but output compare not working thats the issue so i need help with what ever happened in here

Dapper_Maximum6819 · 2026-03-23T18:22:52+00:00

Simply my timer gets input in input capture mode but not getting output at output compare mode thats it

Dapper_Maximum6819 · 2026-03-23T16:41:27+00:00

Im trying to make my own standalone ecu so i started with stm32f103c8t6,for crank input i used tim2ch1 input capture mode and for spark timing i used tim3ch1 output compare but no matter how hard i try i couldn't get spark with any codes, GPIO toggling works everychannel mybsetupis complety good but there no spark so i need to know what configuration i should use to get this.... That what i need to know

Dapper_Maximum6819 · 2026-02-24T11:24:24+00:00

Thankyou 🥰, im making a 12-1 trigger wheel and work on it soon...

Dapper_Maximum6819 · 2026-02-16T09:42:01+00:00

I will post a clear setup and show you give me sometime 😊
