Re: Drive letter of ftpboot

So, I don't have a SD-Card and so no "C:" drive. Does someone know if there is a drive in this configuration? Hi Edgar and welcome to Ultibo, When booting from the network the RPi firmware retrieves the kernel image from the remote server and loads it into memory before executing it, the ...

Re: Read char without echo

How do I determine if there is a key ready to read, so as to not block my thread? I did a quick search and did not find the answer, although I think it has been discussed. Thanks, Mark. There are several ways but if you're using ConsoleReadKey / ConsoleGetKey then the most suitable option would be ...

Re: Access to the on-board flash memory (eMMC) of a CM3+

In Ultibo I have tried to get the eMMC to work without success. Even a try with FSGetValidDrives returns a 0. What is it, that im overlooking? Is there even a support for the eMMC? Hi and welcome to Ultibo. We don't have a CM3+ but we've done some checking of the schematic and device tree info to s...

Re: How do I use the extra GPIO pins in Adafruit's TFT 3.5"

Does that mean in reality you can only use 19 pins out of the original 26? Or are the ones used by the display still useful somehow? Just asking out of curiosity, I think I will be just fine with 19 pins :P You could probably add another SPI device on the SCK, MOSI, MISO lines but there is no oppor...

Re: How do I use the extra GPIO pins in Adafruit's TFT 3.5"

Are the signals from the unused pins in the Pi routed to the pins in the back of the display? Yes, if you look at the Adafruit page for the PiTFT 3.5 it says this: There's a 2x13 'classic Pi' connection GPIO header on the bottom, you can connect a 26-pin Pi GPIO cable to it to use any of the other ...

Re: IR Touch screen

Thanks for all. We'll post here when the experimental driver for your device is ready to test. I wait for you. What we'd like to get to is a set of generic USB HID drivers for Keyboard, Mouse, Touch and Joystick (Gamepad) that will work with most common devices. That's cool!. I'm not a expert progr...

Welcome back, Looking back at this thread it seems that as of our last post we were still trying to resolve two ite...

Re: USB CDC Device

Where can I see any example of working with USB CDC Device ? The device is defined in Windows as a CDC USB device, and allows to work with it through an ordinary terminal (RS232). USB\VID_1234&PID_1016&REV_0101 VID and PID i can change to any values if necessary. The USB CDC specification c...
