Re: 10 pin Li-Po battery connector experiment

Testing LP Alpha's Li-Po charging function.... (in my case) LPA's CC charging is set at 1.89A and when battery voltage reaches about 8.37V, it switches over to C.V. mode. (...) How did you check it ? Just with a LiPo battery or with the battery pack from this thread https://www.lattepanda.com/topic...

Re: Missing Windows 10 pro arduino Leonardo driver

After instaling Windows 10 pro and nothing else, just Windows update, Windows can not see the Leonardo com port, when I reset the Arduino it try to find drivers but it can not. There is not change at all after installing arduino ide and all the usb drivers, so still waiting for you to provide drive...

Re: 10 pin Li-Po battery connector experiment

(...) 3. Notice (I am running Win10 Pro) Windows detected the power in existence and seems to trying to calibrate battery capacity and energy flow-in/flow-out. Without battery pack providing fuel gauge info thru I2C (that SCL and SCK lines unused in LPA doc), the estimation may be pretty crude. (.....

Re: A truly hackable LattePanda

Not really offtopic: Of course, the CPU is the most important thing about a PC, but it needs more, really important and reliable things: 1st The power supply No electronics work properly if the power supply is not really reliable. You can't save any money here. Not at the power supply, not at the co...

Re: Wifi strength issue with Titan Case

I connected them to the circuit board, (...) OK, that's not how I understood it, my mistakes. (...) I mean that I didn't attached them with the adhesive to the case. Do you think that would improve the signal? Right now the case is looking like a shield and I'm concerned about pasting them to it. I...

Re: Wifi strength issue with Titan Case

Every radio link needs antennas.
Only sometimes the antennas are so small that they are on the board. But such small antennas are not very effective, but nowadays they are mostly sufficient.
The LattePanda has no antennas on its board, so the external antennas have to be connected.

Re: Development on Laptop

I am about to start a project built around a LattePanda that will use external sensors/relays connected to the IO pins. However, I will be developing the application on a laptop running Windows 10 using Visual Studio. How can I emulate/provide the same arduino coprocessor capabilities on my laptop ...

I think windows 10 does now give you i2c, gpio and spi access:

Re: Newbie needs to access Uart and IO pins from Visual Studio

I am writing an application in Visual Studio that requires IO and UART access to an external device. I see you can set up an Arduino project but can you mix a native C# program with access to these ports? (...) I suggest you first update the Arduino IDE and then try these examples first: http://doc...

Re: LP Alpha | GPIO control

For people good at electronics and DIY... Intel x86 side of I2C is 1.8V based. Use a PCA9306 breakout board to convert to the I2C boards' required voltage level (some 3.3V based and some 5V based, do not mix them) There are many I2C based boards and devices: General purpose IO, prototype boards, PW...
