Re: Acess the ethernet port with the arduino (alpha)

I was thinking about collecting it from the serial com already established between the processor and the Arduino. I to use windows(or linux cause I don't want windows crashing) to accept the data and upload it. I just don't know of any text software that is able to grab serial data. On Windows I ha...

Re: Fail to power on.

My Alpha, mounted on the back of a 10.1-inch touch screen. Power supply via my own 12V power supply, because the electronics of the LCD also needs 12V. To make the connection compatible with the devices of our company, I had to use the large green connector. (can not upload any pictures at this mome...

I'm convinced that LP should hire you. You seem to know more about their product than they do, and you offer better support.
I totally agree ! ;)

Re: Slow screen refresh

On a new 4G 64G card with most current Windows I am seeing slow windows screen refresh. Just moving the cursor may give a black screen for as much as 14 seconds. I have set the attached LCD display to off in the BIOS -- no help. Device Manager lists Intel Corp driver version 20.19.15.4549 11/10/201...

Re: Lattepada not booting after removing some interfaces

I think you destroyed your LP classic. The PCB certainly has 6 to 8 inner layers with <0.1mm wide traces and micro vias. When desoldering the connectors strong mechanical forces occurred, as you can see on the photos at the yellow-orange places. These forces have probably torn up traces and/or broke...

Re: How to get 3.3v or 5v i2c devices work?

1. You need additional hardware, a level translator. For example the MAX3373 2. You need a driver for the I2C pins of the Intel CPU. For Linux there should be such a thing, but I am not sure. For Windows we are all still looking for the drivers... LattePanda hasn't said anything about it yet. Since ...
