Milk-V Duo Risc-V computer USB input ST7789 240x240 SPI Display

[@MohammedRezwanulIslam]

It will be cool if you make a tutorial about how to use spi display with this board

[@mark.birss_1]

I will look maybe at such a tutorial in the future - for now check out the Milk-V community pages on how SPI display can be used

[@TheShadowOfMike]

Keep the vids coming!

[@mark.birss_1]

Will do

[@ThiwankaWimalasuriya]

your videos are good. can you please make them little longer. im also interested in these little risc-v boards like milkv

[@mark.birss_1]

thank you, will try next time

[@amorpheuses1627]

How are you getting output on the LCD? Are you using one of the Milk-V GPIO pin sets for this? But this is a SPI display so you'd need some other controller to do the conversion.

[@mark.birss_1]

yes, spi output enabled via device tree (dts) and linux framebuffer driver and redirected console output to the display

[@TheEpicGamer13370]

Hi, does the milk V automaticly output the SPI data , or are your using custom code?

[@mark.birss_1]

No, not automatically device tree changes and pinmux setup and enabled linux framebuffer driver, refer to the code changes above patch

hey, my display isn't working, im using a esp32, but it turns on, but never displays anything

[@mark.birss_1]

have you tried follow this guide ?- www.instructables.com/ESP32-and-ST7789-135x240-LCD-Display/

[@Philip8888888]

This is cool! I just got a board and investigating it. Out of interest, how was the input made? Title mentions USB input, but I couldn't see from the video if there was USB keyboard wired into the pin headers.

[@mark.birss_1]

Single USB port breakout to USB keyboard attached to 5V/GND/D+/D- (D+ and D- are pads under the MilkV-Duo board)

@@mark.birss_1 Are you still working on your mestastic blackberry?

[@Freireg1503]

Nice application! Could you share the code you used for this? I've seen this example on the Milk V forum but all the explanation is in chinese...

[@mark.birss_1]

Make use of translate.google.com (what i used) - here is the code - github.com/milkv-duo/duo-buildroot-sdk/compare/develop...markbirss:duo-buildroot-sdk:develop.patch

Did you check the idle power consumption of this device?

[@mark.birss_1]

No, I do not have any good measurement equipment
