Waveshare 3.5inch Overlay for 5B & 5B+?

#1

Hi Radxa Team,

do you plan to publish an overlay to use a Waveshare 3.5inch SPI DIplay with the 5B and 5B+ ?

Or does anybody has a solution?

Many thanks
Henrik

here’s a waveshare 3.5 inch common dtsi: https://github.com/radxa-pkg/radxa-overlays/blob/main/arch/arm64/boot/dts/rockchip/overlays/waveshare35-lcd.dtsi

and here’s a example: https://github.com/radxa-pkg/radxa-overlays/blob/main/arch/arm64/boot/dts/rockchip/overlays/rk3588-spi4-m2-cs0-waveshare35.dts

you just need to modify the spi bus and a couple of GPIOs.

ROCK 5B/5B+ may not fit Waveshare 3.5 inch SPI LCD perfectly, because PIN_22 pin is used as SARADC_IN4 instead of GPIO, you may need to use DuPont cable to connect ROCK 5B/5B+ with Waveshare 3.5 inch SPI LCD.
