  1. Closed: Use "Vector VN1610" and a serial terminal instead of "Vector CANoe"

    Hi guys,

    I hope this is the correct place for my topic, if not please move it.

    I am trying to get a serial terminal to work with "Vector VN1610" because I prefer to use it instead of "Vector...

    Result: the problem really was the etchant. It turns out that only the upper part of the copper was removed, when I scratched the PCB, I saw the rest of the copper layer. Until it turns full plastic...

    I will increase the etch time 24 times and check the results.

    I am using printer toner and a marker for the tracks. I don't think the "sun bath" will remove these residues?

    Closed: Good cheap DDR4 RAM memory site

    Hi guys,

    I found this site which offers a lot of things from "AliExpress", but they filter the sellers for us and only offer us the high quality. If you need something that they don't have, send...

    If it does not have to be in China, you can check these from the EU.

    Closed: Re: SPI protocol with SD card

    Can you post a circuit? If your module has SPI, you connect it to the MCU and then from the MCU to an mp3 player chip, you might be able to skip the MCU.

    I think you want details about proprietary technology. The site I gave you should have a datasheet. Otherwise you need to contact intel about this information.

    Your system configuration is not the problem. I am using "CANoe" too, this happens when you leave "CANoe" without a filter and it keeps sending/receiving. To fix it just clear the messages and send...

  19. Closed: Re: Resistors for high soldering temperature

    Another option is a cooling system, use the box of the PCB as a cooling system, make it metal and add an external cooler, or add an internal fan if its enough and does not interfere with the work of...
  20. Closed: Re: Resistors for high soldering temperature

    Your first problem is that you want it to be "SMD". Use through hole it provides better cooling. Get a 2W resistor and check its ratings on "components supplier". If it can not be used, get a "5W"...

    A good question, I like it. Lets start with this, do you know the difference between "AC" and "DC" current? Do you have 2 separate grounds, do you have an optocoupler between the VAC and MCU ADC? Do...

    This should have been the file on why the voltage increases more without grounding. I will look a bit more if this is not it.
