For the normal RGB screen initialization, an initialization sequence needs to be sent via SPI. Since the Luckfox Pico Ultra has no extra pins, the LF40-480480-ARK uses the MCU to assist in the screen initialization. If you are sure that your screen pins match those of the Luckfox Pico Ultra, you ...

Hello, if you use LF40-480480-ARK the touch chip is GT911, if you still plan to use i2c control, the list of i2c touchscreen drivers supported by the SDK is as follows https://github.com/LuckfoxTECH/luckfox-pico/tree/main/sysdrv/source/kernel/drivers/input/touchscreen

Hello Crocodile
When checking PDF schematic, we saw the SARADC0 connected to Boot button circuit.
This not good for ADC put with pull-up resistor to 1V8.
Really dont have option for isolation the circuit of Boot button on Luckfox Pico Ultra design.
Next, we checked the SARADC1, but saw it connected ...

Hello Crocodile
Yes, I tested, It worked good.
Thank you.

Hello everyone,
I'm testing ADC readings for an external battery voltage.
I'm using a resistor voltage divider with 470kΩ on the top and 100kΩ on the bottom.

When the divider output is not connected to the SARADC_IN0 pin, the voltage is stable. However, when I connect it to SARADC_IN0, the output ...

Hello Crocodile
Thanks for your confirmdation.
One more question, Can I use both external supply and USB same time ?
Pluggin USB cable while the board have 5V external.
Thank you.

Hello Everyone,
Im working with Luckfox Pico Ultra W board.
I want to use external 5V power supply to board instead using power supply from type C port.
I tested with by wiring the 5V power supply to P1.2 and P1.6 pins, but seem the board cant run.
Please help to review and show me a solution ...

Hello Crocodile
Thank you for your feedback.
Yes, I understand. My purpose is find a way to reduce a output capture res/rate of image from camera due to CPU is near over 100% by multitask.
Im thinking about changing to another dev board with larger than 1 core, could you please recommend another ...

Hello everyone.
We have a project which are working on Luckfox Pico Ultra W and camera module MIS5001.
We would like to know a kernel have support for capture image from camera with adjustable parameters (capture size, rate, ..)
We looking for a datasheet for MIS5001 sensor, but we could'nt find it ...

Hello Crocodile
Its OK for find touch controller part number.
Thanks for your support.
