https://github.com/raspberrypi/linux/pull/6029 (Mar 13, 2024)

The driver has been converted to use gpiod, which will normalise polarity based on DT.

The piscreen overlay (and others) incorrectly defines the pendown GPIO as being ACTIVE_HIGH (0), althought triggering on the high-low edge for pen down. It therefore tries reading the pen position when not being touched, and stops when it is touched.

Tested with piscreen and ads7846 overlays. Also fixed on others where the interrupt says high->low but the polarity was ACTIVE_HIGH.

ADS7846 Touch controller does not work anymore after upgrade to the latest kernel 6.6.20 on 64-bit Raspberry Pi OS Bookworm. It works well with the older kernel 6.1.0.

在 Klipper 中使用 Fly 3D 的 D5

以前買來就直接使用。最近，怎麼都連不上。比較裝置的代碼，才發現不同

 /dev/serial/by-id/usb-katapult_stm32f072xb_MELLOW-if00

燒了 Klipper 的 firmware，應是

/dev/serial/by-id/usb-Klipper_stm32f072xb_3C0029000557465036383420-if00

原來，在2024年9月1号之后出厂的D5已经刷好Katapult固件。 

照著它的文件，就可以重新設定和 build 映像檔了。

https://mellow.klipper.cn/docs/ProductDoc/MainBoard/fly-d/fly-d5/flash/usb

燒入的指令

~/katapult/scripts$ python3 flashtool.py -d  /dev/serial/by-id/usb-katapult_stm32f072xb_MELLOW-if00

喇叭要關掉，要設 default 值。
