one day : this is not that day though hah cheers for posting!

Basic software testing is now working. Finally found out one of the wired pins for transmission was not usable. No idea why it’s not marked as any special pin and acceptable for use with canbus controller. It just doesn’t work. Wired another pin and everything just started working ok.   Now have a few more tests for the hardware to figure out the resistance values for the pins that control the canbus listen-only and shutdown.   You need to balance their internal resistance that wants to make the chip active and transmit the default, vs the external resistors I added to make it shutdown and passive at power up. You need to make the resistance as high as possible to the shutdown passive state as possible that you can overcome with the microcontroller.   Tonight will make pcb changes to swap the pin that caused issues to the next closest and add some more places for resistors to both to power and ground. That way swapping resistors can be done on the board as needed. It also allows the canbus controller chip to be a different model that has different need to resistance high or low. PS figured out some of the download issue were the voltage regulator on the serial port adaptors I have. Using usb supplied 5v through the regulator on the pcb works ok. Guessing they can’t supply enough current as they are cheap and under speced.

I’ll be going, on the Saturday - anyone else heading out? would be cool to see some club subbers there come say hi if you see me 💯  

I got the dashcam in the GT-B the other day and managed most of the radar detector install too. I need to wrap that up! Last two real things do to are install this Fujitsubo and rear shocks. It is as hot as Hades here these days.    Also signed up for two days on track in October. Planning to take the 2000 GT one day and the 2005 GT the other. The Subaru Stork may also be making another delivery in a week or two...stay tuned.

So far, so good. canbus drivers etc all installed ok. Also found that every reboot of pc that programs the microcontroller it resets the memory size and partitions where normally it remembers them. This isn’t a big deal but is annoying. A custom board description file will fix the issue, so have to learn that next. It will help with final version for others to customise and install their own software.   Tomorrow I have to dig out laptop with the canbus software and usb canbus sticks  and setup a testing network again.
