Nuvoton NT-M0564V Development Board

Testing the Nuvoton NuTiny-SDK-M0564 – development tool for the M0564 series microcontroller.

The M0564VG4AE is a Cortex-M0 microcontroller which can run at up to 72MHz, features 85 I/O pins, 256 KB Flash, 20 KB SRAM, 4KB ISP ROM and 2 KB SPROM(Security Protection ROM).

The 161 pages datasheet can be downloaded from here: http://www.nuvoton.com/resource-files/DS_M0564_Series_EN_Rev1.00.pdf

The whole Development Package can be downloaded from http://nuvoton.com/NuMicroDVD/

The archive contains some useful AppNotes, drivers for Keil and IAR, CooCox BSP, Datasheets and some useful stand-alone programs like ClockConfigure Tool, NuMicro PLL Generator Tool.

The next steps are: install and configure Keil, add packs, CMSIS… etc.

For Arduino Fans there is a NuMaker Uno Board based on NUC131 – another Cortex M0 ARM – https://direct.nuvoton.com/it/numaker-uno

The amazing small board – NXP LPC800 by NGX

The amazing small board – NXP LPC800

LPC800 series develeopment tool

I just get my hands on this board courtesy of Element14.

It’s amazing. Simple and efficient.

The small pin number is compensated in a great way: The Switch Matrix – it connects 6 pins to any available internal module.

Of course, programming can be done in bootloader mode, where every pin is reassigned according to the original layout.

LPC810 features:

ARM Cortex-M0+
Switch matrix for flexible configuration of each I/O pin function
2 USART interfaces, 1 SPI controller and 1 I²C-bus, with pin functions assigned through the switch matrix
Self Wake-up Timer (WKT) clocked from either the IRC or a low-power, low-frequency internal oscillator
CRC engine
Boot ROM API support: boot loader, USART and I²C drivers in ROM, power profiles, Flash In-Application Programming (IAP) and In-System Programming (ISP)

The debugging options supported are SWD (10 pin connector), JTAG boundary scan and Micro Trace Buffer (MTB).

The quickest/cheapest programming method is via ~~spi~~^*ISP (6 pin connector) with a USB/Serial cable.

mbed – ARM Rapid Prototyping Tool

The mbed Comes in two flavors: CortexM3(NXP LPC1768) and CortexM0(NXP LPC11U24).

Here is the LPC1768 version, a 2×20 pin /2,54mm DIP board easy to use with breadboards.

1 ethernet port
3 serial ports (Rx/Tx)
2 SPI ports
2 I2C ports
6 Analog INs or 5 Analog INs + 1 Analog Out
1 CAN Port
6 PWM out
1 USB port (D+, D-) and the main USB-mini Port as a serial terminal
4 blue LEDs

Connected to USB shows up a 2MB FAT-FS storage with a preloaded web page which connects and autenthicates the user to the mbed.org website where resides the Free Online C Compiler and all other help pages, manuals, code examples, community contributed programs and libraries.

Loading a program is simple as drag-and-drop, you only need to drop the binary file on the MBED drive and the MBED Interface does all the programming after a board reset.
