Re: Another Sleep-Wake thread

Hey, much to my delight, I discovered my new Alpha came with a wake-on-RTC function in its bios. Thanks for implementing this! According to preliminary testing it works fine as long as the Alpha is on a steady power supply. But if there is any kind of power interruption, it does not wake up after th...

Re: Another Sleep-Wake thread

I'm controlling Arduino via firmata from visual studio. This is simply awesome. PC and Arduino fused their souls and act as one :) Question: When controlling servos, we can set the angle.

But I can't find any for LattePanda! At the moment the only solution seems to be to use the Gravity IO expansion shie...

Another Sleep-Wake thread

I'm evaluating a Lattepanda 4G/64 model for a project involving solar-powered remote devices. They need to sleep through the night to conserve battery. I tested power consumption using Windows' built in "When plugged in, PC goes to sleep" function. Currents are measured at 13.6V. There is a small st...
