Re: LattePanda Delta power.

Please check the exact item you plan to purchase to see if USB-C power supply is included or not. Previously, the SKU on LP eStore's LP Alpha or Delta did include a 45W USB-C power supply with non-detachable USB-C cable for powering the SBC. On the other hand, you may find getting your own, suitable...

Re: Latte Panda Delta i2s audio output

In I2S audio world, there is no "plug-n-play, it just works". Your "test board" depends on chipset used, will have to have many hard work people already figured out the solution (BIOS setting, APU IO enabling hardware driver, ALSA driver, etc., etc.) IO voltage level has to be right, audio framing h...

Re: Lattepanda Alpha I2S

Please be forewarned that I2S codec interface is different IC specific and lots of work involved. There seems to be BIOS, machine-specific device driver, ALSA driver, etc. all needs to be tuned as well as hardware signal interface voltage level needs to be correct.

Re: Get 4k 60hz

LP Alpha's CPU/GPU can only support 4K (3840x2160) @ 60Hz from its DP port or eDP port, not from its HDMI port. So in LPA case, the 4K @ 60 can be accessible from its USB-C port with a proper dongle (e.g., USB-C to HDMI adapter) , thru a proper USB-C power injector + HDMI combo dongle, or a proper 4...

Re: Freezes over longtime usage

Intermittent issues are hard nut to crack. If you suspect its a hardware related issue, first thing to do is to change to a high quality power supply. If suspect a software related, try to run a routine watchdog program to frequently send a message to a port to ensure the OS is running (while a spec...

Re: Arduino not Working on LattePanda Delta 432

/dev/ttyACM0 is connected to the on-motherboard/built-in ATmega32u4 (Leonardo.)

Don't know how you connect the external Mega2560 board. Please use the proper communication port to the 2560 board.
