Hello,
Thank for all your answer !
I’am not using PCBv2. I’m using a home made PCB based on the old wiki schematic, with the following modifications:
- PIN assignment adapted to the actual INO
- Add opto circuit (like on PCB v2) for the switch
Some pictures can be seen here: Implement on a Fiat F100 success
For voltage drop hypothesis, the architecture of the power supply of the board is like this:
It mean that the voltage drop du to the motor throught the IBT2 Power Side + 12V to 24V Step-Up Converter have to be suffisant to generate a significant power drop on the tractor 12V bus. I haven’t noted a visible voltage drop on the tractor electrical system (like loose of indication on the dashboard or something like this). What do you think ?
Powerline noise, it could be: it seems it have to be propagated throught the LM2596. But not easy to check that: the only way I saw is to monitor the 5V output of the LM2596 with an oscilloscope (that I don’t have). Or any other idea ?
For the USB hub that I use with the Surface Go, it is an unpowered USB hub. But the problem also appear when I use my Acer Labtop and I don’t use USB hub with my labtop (enought USB port on it for connect GPS antenna and Arduino without USB hub). It’s why for me, the USB Hub is not the cause.
Don’t understant the question. For me, Arduino Nano use a FTDI FT232RL chip for UART/USB convertion.
I have to check this. But the Surface Go is brand new: Get It out of the box, just made the Windows 10 updates, unistall all not necessary software furnished with Windows, and only install AGO & Arduino IDE on it. So I could unistall Arduino IDE, but apart from that I have no other idea.
And It seems the problem appear only when the steering is engaged.
Ok I will try this. Bluethoot was on on the 2 devices during my tests.
Ok I will try this to.
Thank again for your help !
