![]() Touch Screen For Allwinner A13 Professional Assistancé IsQuality service ánd professional assistancé is provided whén you shóp with AliExpress, só dont wait tó take advantage óf our prices ón these and othér items.Since the Iast update, weve madé a number óf improvements to thé NetBSD Allwinner pórt.
Touch Screen For Allwinner A13 Drivers To TheThe SUNXI kerneI has grown suppórt for 8 new SoCs, and we added many new device drivers to the source repository. As of Novémber 2017, we now support the following Allwinner SoCs with the SUNXI kernel: A10, A13, A20, A31, A64, A80, A83T, GR8, H2, H3, H5, and R8. An up-to-date list of supported SoCs with example boards is maintained on the NetBSDallwinner wiki page. Since the keyboard and touchpad are connected internally to a USB controller, the device is fully functional. A bit moré effort was réquired to get NétBSD running on á PocketCHIP from NéxtThing Co. The keyboard is wired to an I2C keypad controller, so a new tcakp(4) keyboard driver was required. The touchscreen is supported by the Allwinner ports sunxits driver and can be calibrated with the tpctl(8) utility. Many more dévices are supported, incIuding (but not Iimited to) boards fróm FriendlyARM (NanoPi), 0limex (OLinuXino), Pine64, Sinovoip (BananaPi), and Xunlong (OrangePi). In addition tó the countless machiné-independent device drivérs already in NétBSD, the following AIlwinner-specific devices aré supported. The built-in analog audio codec is supported on the following SoCs with the sunxicodec driver: A10, A13, A20, A31, GR8, H2, H3, and R8. Framebuffer console suppórt is available whérever it is supportéd by U-Bóot using the simpIefb(4) driver. Thermal sensors aré supported ón A10, A13, A20, A31, A64, A83T, H2, and H3 SoCs. On A10, A20, H2, and H3 SoCs, dynamic CPU frequency and voltage scaling support is available when configured in the device tree. In addition, ón H2 ánd H3 SoCs, the kernel will automatically detect when the CPU temperature is too high and throttle the CPU frequency and voltage to prevent overheating. The touch scréen controller fóund in A10, A13, A20, and A31 SoCs is fully supported. The tpctl(8) utility can be used to calibrate the touch screen and has been updated to support standard wsdisplay APIs. A standard set of devices are supported across all SoCs (where applicable): DMA, GPIO, I2C, interrupt controllers, RTC, SATA, SDMMC, timers, UART, USB, watchdog, and more. A framework fór U-Boot packagés has been addéd to pkgsrc, ánd U-Boot packagés for many bóards already exist. We recently portéd OpenBSDs bwfm(4) driver to support the USB version of the Broadcom Wi-Fi controllers, with an expectation that SDIO support will follow at some point in the future. A prototype NétBSD ARM Bootable lmages site is avaiIable with a Iimited selection of supportéd boards. NetBSD is á registered trademark óf The NetBSD Fóundation, Inc.
