Timer/Capture for Control – “TCC’s”

You may have noticed a difference between classic Microchip MIPS based devices, and the SAM Cortex ARM family of MCU’s regarding PWM’s and TCC’s. They are interchangeable terms however it should be noted that the TCC’s are counted in single instances that include multiple input and output channels.

TCC’s Support a multitude of real time control extensions:

  • Up to 8 compare / capture channels per TCC instance
  • Frequency, Single- and dual-slope PWM
  • Input Capture
  • Waveform extensions
    • Output matrix – CC channels distribution across pins
    • Low- and high-side output w/ dead-time insertion
    • Waveform swap option
    • Pattern generation
    • Dithering
    • Double buffered registers
  • Event inputs
    • 2 events input for the counter
    • 1 event input for each CC channel
    • Any system internal event can be selected to trigger actions in TCC (use Event System)
  • Event outputs
    • Overflow, Compare Match or Capture
    • Can trigger various system actions by using the Event System

Simulation and modeling tools

SAM D/E5x devices are supported in the open-source simulation package Scilab.  Scilab is a 2-piece modeling environment made up of the Scilab main, and Xcos system modeler.

Software and Hardware Development Tools

SAM CD5x series devices are supported in the Microchip/Atmel Studio IDE, Atmel Studio framework, and START for software examples and configuration. Sensored and Sensorless BLDC software is available in START for free and features a reduced order Leunenburge type control loop.

For hardware development, protyping and debugging, the SAM  E/S70 series is supported with an Xplained Pro kit for the SAM E70 MCU which is the family super-set device (ATSAME70-XPLD) that supports Arduino style add-on boards. For BLDC Motor control applications, Microchip offers a 24 Volt development platform – ATSAMD21BLDC24V-STK -  featuring a complete power stage, motor, and swappable Plug In Modules that support the C21, D21, D54 and other devices. 

Customers looking to develop motor control applications with the D/E5x series on the BLDC24V-STK kit must purchase the ATSAMS70MOTOR card. (coming April 2018)
