Microchip evaluation kit for mid-range touchscreen applications

Apr 19, 2022 — by Giorgio Mendoza 375 views

Microchip’s SAME51 Touch Curiosity is a low cost evaluation kit equipped with ATSAME51J20A MCU, a touch-screen TFT display and an onboard debugger for quick product development. This kit is designed to aim applications requiring touch input and clear display such as smart appliances, vehicle climate control or industrial embedded devices that require CAN, Ethernet or USB support.

The evaluation kit adopts the 32-bit Arm Cortex-M4F MCU which has a maximum frequency of 120MHz. Other relevant features include a Floating Point Unit (FPU), a Memory Protection Unit (MPU), 256KB SRAM and a 32-channel Direct Memory Access Controller (DMAC).

According to Microchip, the eval kit has an Integrated Peripheral Touch Controller processed by the MCU which completely handles the touch user interface without and the rendering required for the display.

Furthermore, Microchip provides support to implement 2D touch, basic gestures, and even machine learning for gesture recognition to improve the user interface experience. The board contains an Onboard Nano debugger for simple programming and debugging.  The board is supported by the MPLAB X IDE and MPLAB Harmony v4 software development framework. Microchip ensures that no external tools are needed to program the device.

    Who in their right mind would use anything Microchip these days. They have been the worst with this supply chain shortage. Others have no real problem like Espressif. So many engineers I talk to are swapping out their MC parts for others, and will never to to them again.
