Re: only had 1 set of TX, RX(pin 2 & 4,U2) pins for serial communication

Dear Lattepanda, I understand that the Arduino side of the LP board is based on Arduino Leonardo which only had 1 set of TX, RX pins for serial communication. I need 2 sets of these pins for my current project. Is there any way to have 1 more set of TX RX pins for the LP board, such as connecting a...

Re: Pin to Port connections Atmega32U4

Sometimes the LP team is a bit slow...
Why "bad assumption"?
Maybe we users can answer you a more detailed question?

In addition, an overview of how the Arduino and the PC part are connected could help to clarify some questions among the "non-technicians" among the customers.

Re: Core UART serial ports on Z8350

I think the first problem is the different markets for which LP is now active. On the one hand the market for hobbyists and on the other hand the market for professionals. Both expect different functions and therefore different documentation and different communication. In addition, the technology o...

Re: Core UART serial ports on Z8350

Hi hvguy, oh, yes, the BIOS, I forgot. I am an experienced developer of microcontroller circuits, but I know little about the inner structure of a PC. Maybe that's why I don't understand why drivers for the second serial and the two I2C are such a problem. But in the meantime I fear that we will hav...

Re: Core UART serial ports on Z8350

(...) As a operation team member, to be honest, activating CPU part feature and open more docs / resources on it are our pain. (...) Would you mind to share how will you use these GPIO from CPU side with us? (...) OK, let me make a few comments. Negligent documentation : http://docs.lattepanda.com/...

Is there any documentation on accessing the i2c bus from the Intel chip side(not arduino chip)?
We are all waiting for over 1 or 2 year now for sources and examples on this...
I think, we have more than 10 topics on this in this forum. :cry:

Re: How to access GPIO using Pyhon?

The GPIO are connected to the onboard "Arduino Leonardo".
The Arduino ist connected via USB-Serial to the PC.
Maybe you should take a look at the Arduino community web sites for using Phyton with Arduino.

... and update the Arduino IDE on your LattePanda first.

Re: Core UART serial ports on Z8350

The above picture is a little bit outdated...
This is the actual one : http://docs.lattepanda.com/content/hard ... ndOutputs/

I knew nothing about Linux, but in Win10 the COM1 is at pins 5+7 (UART0) with a voltage logic level of 1,8V !
