PDM25 V1 CAN Stream
I have a PDM25 V1 and a PDM25 V2.
The V2 exposes the hardwire can stream contents in the configurator and I'm good with that, but the V1 doesn't.
I hoped that, by ticking the enable stream checkbox and selecting the Hardwire option, it would output a similar stream.
That doesn't seem to be the case and you can't load a config file in either.
I've looked at the hwpdm file (JSON) in the hope that I could just paste in the file from the V2, but the properties are different.
Also, the v2 stream uses 40 frames, which would use all of the available frames in the V1, which isn't ideal.

PDM25v2 FW 1.3.0 CAN IMU output
I would like to stream IMU angle over CAN with my PDM25v2 on FW1.3.0. I have enable the can stream and is able to monitor the CAN message coming out. What I am concerned about is that all the value for angles are exactly zero while variable monitor is showing small angle of +-0.05 so I would expect to see some values in the CAN stream. The module is already mounted so tilting it to check might be harder to do so I would like to check if I am missing anything before diving more. Additional information is that the IMU is shown to be uncalibrated in the IMU tab so I'm not sure if that would gate the CAN output although it is showing on variable monitor. If IMU needs calibration, what is the process as I do not see the necessary GUI element for calibrating the IMU.

pdm can issue
i have a pdm15 was working just fine and now it won't work at all. keypad turns on but when buttons are pressed nothing happens. Dash turns on, windows work. no keypad functions work. firmware wont update and can't program. keypad and dash are very slow to turn on as well. Takes a lot longer than it used to for it to wake up. nothing has changed.

Hi, Please send your config to contact@hardwire-electronics.co.uk It sounds like a CAN bus issue. check the CAN wiring and check the termination resistors.

Upgrade then restore backup?
Is it still true that it's not possible to restore a config backup after updating the firmware? I'd like to update my PDM25+ from 1.1.5 to 1.1.6, but don't want to set the whole thing up again like last time.

pre June 2020 PDM15 Input upgrade?
Does anyone know is a pre June 2020 PDM15 be upgraded to have pull down resistors ?
Without them I am having to put additional external components into my wiring that I'd rather not do.
I've been looking at making a simple PCB with grounded 10K resistors for all inputs. Don't supposes anyone has done this already and might share a PCB design?

Holley Dominator CAN Setup on PDM25+ V1. v1.15
Trying to get Holley Dominator CAN data working on an older Hardwire PDM25+ V1. Firmware 1.15
The newer PDM28 imports the Holley DBC fine, but the older PDM25 software doesn’t have a Float data option.
I know this has been done before. Does anyone have the correct setup or an old Holley/PDM25 configuration they can share?
Mainly trying to get RPM, MAP, TPS, coolant temp, etc. working over CAN.

Well I noticed v 1.16 has the data format: float available but I've been unsuccessful using that version, whenever I send a simple output command it hangs the PDM. Maybe I'll try again. Not ready to give up yet. Especially since the whole car is wired up

over current on all outputs
Hoping to get some guidance on this. This is my first PDM and have been enjoying the experience until today. This is a fresh build that is undergoing the shakedown phase. I have PDM25 that is controlling everything on my car and has been working well until today. I backed out of the driveway and the car shut off. pushed it back in the driveway and opened the laptop to see all the active outputs in over current fault and cant figure out why. The only things I've changed since the last drive was I moved a shared output to its own individual one (as I had some extra space)and it worked for the first few minutes during engine warm up before it died. I have even unpinned that output and its still shows over current fault unless i disable it. What could cause this type of failure? I spent…

A buddy from work kept insisting that I check out a new platform he'd discovered, claiming it had the smoothest interface and the most responsive design he'd ever come across. I was skeptical because he tends to get excited about things that look good at first but fall apart once you start using them. But he was so persistent that I eventually gave in and decided to take a look. When I visited Shorelines Casino, I was immediately struck by how well everything was laid out. The homepage loaded quickly, the menus were intuitive, and the overall flow of the site made sense without any unnecessary clutter. I spent some time clicking through the different sections, testing how responsive everything felt, and I was surprised by how smooth the experience was. My colleague and I often disagree on these things, but this time he had a point. I sent him a message admitting that Shorelines Casino was actually decent, and that I could see why he had been so insistent about it.

counter memory
does anyone know if their is a way for the pdm to hold the count of a counter after it has been powered down. for example, i have a loop around counter for an electric ebrake. 0 is disable ebrake, 2 is nothing 3 is apply and 4 is keep button light on. 2 and 4 are holders after a set time or current limit is reached. my issue I'm having is if i apply the ebrake it will hold the button light on and ebrake on. but if i cycle the ignition off and back on the ebrake stay active because with ignition on it cycles the counter to 2 which is an empty holder. but in order to get the light to come on stating the ebrake is still applied you must press the button again and it will move counter to 3 run ebrake calipers and the…

Looking at how Canadian users discuss online gaming platforms, I’ve noticed that practical details are receiving more attention than they once did. Promotions may still be part of the conversation, but topics such as clear policies, responsible gaming features, and dependable performance across different devices are also frequently mentioned. I usually take a similar approach when exploring a platform and first check whether its rules are explained in an understandable way and whether the navigation stays consistent during regular sessions. In several conversations, I came across Dakota Dunes Casino as a recognizable name that some users connected with a straightforward and established experience. What caught my attention was the emphasis on usability and trust rather than promotional offers. This broader perspective has become increasingly noticeable to me when comparing discussions from the past few years.
