For Q2 2014, Allwinner was reported by DigiTimes to be the third largest supplier to the Chinese market after Rockchip and MediaTek.

Īccording to DigiTimes, in Q4 2013 Allwinner lost its number one position in terms of unit shipments to the Chinese market to Rockchip.

In 20, Allwinner was the number one supplier in terms of unit shipments of application processors for Android tablets worldwide. Since its founding in 2007, Allwinner has released over fifteen SoC processors for use in Android-based tablets, as well as in smartphones, over-the-air OTT boxes, video camera systems, car DVRs, and car media players. It has a sales and technical support office in Shenzhen, Guangdong, and logistics operations in Hong Kong. The company is headquartered in Zhuhai, Guangdong, China.

Manufacturability was a top priority in the design of the Recore. While his last one had to be abandoned because of manufacturing issues, he learned from that experience. has a long history of building printer controllers.

You might learn some tips from the other short videos in the series featuring some interesting debugging and problem solving sessions. Watch the short video down below to learn how he solves a few of the nitty-gritty implementation details such as timers and communicating with the Linux processors. But the AR100 is extremely underutilized, and takes good advantage of this by repurposing it to those real-time tasks associated with a 3D printer controller. See that small box labeled AR100 at the top of the block diagram? Meet the AR100, a controller originally intended to manage low-power operations of the A64. It turns out that there is already a secondary microcontroller hidden in plain sight, integrated into the A64 itself. could have addressed this problem by putting a secondary microcontroller on the board, but he found an even more elegant solution instead.

“But Linux is not a real-time operating system”, we hear you cry, “and controlling stepper motor drivers from an A64 SoC is just asking for trouble”. The Recore board is powered by an AllWinner A64 system on chip (SoC) which packs four ARM Cortex-A53 AArch64 cores running Debian Linux. The applications include Klipper, a project we wrote about when it was first introduced, and the OctoPrint print server. ’s design merges these together into one compact 12 x 12 x 4 cm package. Many setups also have a second computer, often Linux-based, which is dedicated to supporting tasks like running an Octoprint server and interfacing to a digital camera to monitor print progress remotely. The typical 3D printer has a dedicated controller which handles the real-time aspects of driving stepper motors. No stranger to the world of 3D printers, from the workshop has released a new controller board called Recore.
