This will make the local copy of the whole bunch of not needed stuff - hardware files, etc. That's a pity there is still no known way to copy just the source files required for firmware build.

What if using ts just for configuring, while analyzing tracks in logic analyzer? Saleae now have several analog channels, plus here are (if i am not mistaken) opn source variants (sigrek?) - but this would require saving logs in those formats..

This could be a handy tool to make timestamps of interest in the logfiles... This would probably make the further analysis of logs a bit easier.

Just a thought: with all these wireless connectivity options, security becomes sort of a concern. I'd suggest to implement a 'read-only' mode for such communications, to be enabled/disabled either with a physical jumper or a password-protected checkbox.

Let me know when (if) you start selling it - I would be happy to by one of these. :D The advantage of esp32 is that it can be used not only via bluetooth, but also as a wifi (dunno, either a client, or an access point) The drawbacks are: these boards are probably trickier to set up, plus BT is BLE-m...

funny thing: I was about to place an order for a breakout board for an automotive ECU connector to be wired to my old frankenstein (finally realized that those small round-shape connectors I had first chosen were just pain in the ass), and the very same day there was a post by andreika with his modu...

what are the benefits of onboard MAP sensor?
the enclosure is made of aluminium - will it work with bluetooth?

Nice! Couple of dozen components are on the other side of the board - probably need to be soldered manually, but that's okay. If there are some extra pins abailable in the connector - I would add an onboard pull-up to 12V resistor for the vehicle speed sensor + corresponding pins. What's the purpose...

but wait! shouldn't there be a reliefe valve in the cap of the expansion tank?

That's an awesome trick! Haven't heard of using such sensors in mass production vehicles. I'd like to see the implementation of such a solution - I mean, the sensor part number, its proper location, etc.

what's the usual way of checking engine temperature? from the coolant temperature sensor? what if there's a crack in the rad, and all the coolant has run away? will the sensor still provide valid values? i mean to say, for the peace of mind coolant level sensor is a must.

you mean to say pb5 and pb6 of stm32f405rg56 are not 5v tolerant? according to the datasheet, they are! or they are only 5v tolerant as general GPIO, but not for CAN purpose? is it a 2 layer or a 4-layer board? you can still use it: replace the can transceiver with 3.3v-powered one, cut the 5V suppl...

I'd suggest that instead of investing in a 3D printer, you invest in a milling machine
What was rationale behind the 3d-printed case vs aluminum one?

Does it allow to filter out parts that are out of stock?

that's yet another rusefi ecu, this time based on proteus board! nice! was it a batch?

lucky you are that it was not rigol
RIP, yet another MRE
though not sure that your reasonoing is valid...

ha! thank you for this hint
STM32F042K6T6
even though it is in extended parts, for a batch of 5 boards it will be even cheaper.

gepro, now it becomes clear - i probably have missed that part :) mck1117, f0 don't have canbus, do they? 405 seems overkill for my purpose, however, for a batch of 5 boards the cost difference would be under $8 - probably, not that much. still, why should I choose them if the one from blue pill wor...

gepro, just curious, what was the goal of the whole exercise? :D mck1117, I meant exactly that. so, how many parts in the design are not from the basic domain, i.e. what extra fee you had to pay for the whole project? I bet it's more than $50.. all in all it's all about the balance (getting rid of s...

you are so quick! how old are you?

offtopic: Do you think these BTS3028SDR will be enough to drive solenoids used in pneumatic suspension? ontopic: 1) I looked through schematics, and there are many parts that are from JLCPCB's extended list, which means another $3 per each component, and this adds up quite quickly - may be there are...

речь об этом: https://rusefi.com/forum/viewtopic.php?f=4&t=1646 но раз сам не нашел - значит, плохи дела. :D заморочки: во-первых, размещение заказа на jlcpcb, которое стоит каких-то наверное значительных денег для минимальной партии. во-вторых, они не монтируют through the hole компоненты, а то...

кстати, возможно, в одном протеусе бы поучаствовал.

In my case, the needle in the cluster was driven by voltage from 0V (full tank) to somewhat 12V (empty), but it's electronic circuit there, not just a winding. In your case (old-style dashboard) this winding is driven by current, so may be you don't need it that difficult, and simple pwm will do.

In a similar situation I used the following scheme to drive my fuel gauge needle on mazda rx8 dashboard: Снимок экрана 2020-11-11 в 18.17.15.png The R and C values are surely specified randomly here, but if you need it, I can give you exact values that helped me with a 5V setup (you'll definitely ne...

actually not free. ~$2 vs ~$0.1
looking for a 3v controlled switch to drive relays, so what's wrong with that solution? will replacing that 100k resistor with a 100-ohm one help?

a rotten can-bus wire? you'd need to invest in a cable tracker to investigate such issues...

so beautiful! congrats!
"theft prevention standards"? may be that's the root cause of zero reation on start button?

был идиотом. проверил, подав сигнал с PD1 на PC6, - обороты запоказывали. ну и задержка стрелки на бензобак - секунд в 20. просто раньше при экспериментах там было все замкнуто, и при включении приборки оно сразу показывало. а тут манипуляции проводил с уже подключенной приборкой - и тода стрелка дв...

я так понимаю, нужно попробовать найти бандл до этой движухи?
https://github.com/rusefi/rusefi/pull/1200

а где-то существует архив с такими бандлами?
