Unpacking a Atmel SAM4N Xplained Pro Evaluation Board

The Atmel SAM4N Xplained Pro evaluation board contains a ATSAM4N16C microcontroller. The board itself is rather basic with only one user programmable LED and one user programmable push-button switch (the second switch is a reset switch). Pins of the microcontroller are available on headers on the board.

An on-board Embedded Debugger is included on the board, so that no external tools are required to program or debug the ATSAM4N16C.

The video below shows the evaluation board being unpacked.

Some features of the ATSAM4N16C microcontroller are:

  • ARM Cortex-M4 that can run up to 100MHz
  • 3 USARTs and 4 UARTS
  • Real Time Clock (RTC) with calendar and alarm features
  • 10 bit ADC and DAC
  • 1Mb Flash memory
  • 80kb SRAM
  • The usual SPI, TWI, timers, PWM, etc.

The ATSAM4N16C does not contain any USB ports, Ethernet or external bus.

Programming STM32 Microcontroller Flash in Windows

STM32 ARM Cortex-M3 microcontroller from ST Microelectronics can be programmed in Windows without the need of commercial programming tools or the need to install any toolchain.

Using the free STM32 ST-LINK utility software from ST, STM32 microcontrollers can be programmed using an external ST-LINK (e.g. the ST-LINK/V2) or using the embedded ST-LINK that can be found on ST evaluation boards such as the STM32 Value Line Discovery kit.

This tutorial on the Starting Electronics website explains how to install and use the ST-LINK utility software.

STM32F4 Discovery Review

The STM32F4-Discovery evaluation board from ST Microelectronics is a low cost board for evaluating the STM32F4 range of 32-bit ARM Cortex-M4 microcontrollers. The board includes a 3-axis accelerometer, microphone, and audio DAC with class D amplifier. Read the review of this evaluation board.
