The Wino board is an Arduino-like stackable development system which is both smaller and cheaper than Arduino units and features built-in WiFi as standard.

The main Wino controller board measures 26.5 x 18.5 mm and fitted with an Atmel ATSAMD21 running at 48 MHz with 128 kB Flash storage and 16 kB RAM. The board uses the ESP8266EX WiFi module which supports all the 802.11 b/g/n standards offering P2P and soft-AP modes and TCP-IP / UDP, static IP and DHCP networking. The 27-pin stackable connections around the board periphery provide connections for 15 digital GPIO pins, 6 x 12-bit ADCs and a 1 x 10-bit DAC.

I will start from saying that the board could be replaced by any Arduino plus some(s) its motor driver shield(s). So why I made it you may ask? Well, while I made this tiny tank-robot model presented on below pictures, I wanted to make at least some things by myself, and decide what I need and how I need it instead of only buying prefabricated stuff.

If you can beg, steal or borrow an Atmel ISP programmer, then you can use the Arduino environment to develop on the Atmel AVR Atmega328P Scorpion Board. An Arduino on Scorpion Board guide, Optiboot bootloader and example sketches have been added.

If you own an Arduino Uno board, you can now try out the Piconomic FW Library risk free without abandoning the creature comforts of the Arduino environment. You can use the existing Optiboot bootloader to upload code. I have added a getting started guide for the Arduino Uno. There are examples, including a CLI (Command Line Interpreter) Application that creates a “Linux Shell”-like environment running on the Arduino Uno so that you can experiment with GPIO, ADC, I2C and SPI using only Terminal software (for example Tera Term)… it is really cool!

An autonomous AVR ISP programming device with SD-Card, Nokia display, ZIF socket and standard 6-pin ISP interface:

From project to project the number of hex files on our PC was increasing. Many people send us their virgin ATMegas to get them flashed. And last not least distributing PCB’s and pre-flahed chips via agile-hardware forced us to burn many, many AVRs. In principle this is a work an ape should do but reality was different. So we spend munch time in this boring job. To much time …

Thus it was just consequent to think about a device that would do the job for us. Here is the result, the SolderLab Easy Auto Programmer V1.0. An All-in-one AVR programmer with SD-card, Nokia Display, a ZIF-Socket and a 6-pin ISP interface. With this device the programming of an AVR is done in seconds including the setting of fuse bits (before AND after flashing), flashing the chip, verifying the flash. And all this without any connection to the PC and by pressing just one single button. You just have to put all your hex files into a folder called “hex” on a standard FAT32 formatted SD card, put the card into the programmer an supply it with some voltage (7-20V). That’s it the rest is done by the “ape”.

This minimalistic board is packed with features and comes with an extensive ecosystem of documentation and firmware.

For the student (we are never too old) that wants to fast track his career as a professional firmware developer there is:

  • a detailed getting started guide
  • an Atmel AVR quick start guide, with tutorials and examples
  • Recommend best practices

For the developer that wants to improve his game there is:

  • A header to quickly connect different kinds of peripherals (GPIO, A/D, UART, SPI & I2C). Notice that each interface has it’s own +3V3 and GND pins to make wiring easier and also improves EMC.
  • A full-featured CLI application to experiment with the connected device and verify that it works, before committing to a single line of C code.
  • A firmware framework that lays the foundation so that you can quickly develop a new application.
  • A Temp&Pressure Logger and Analog voltage Logger application that demonstrates how you can quickly develop your own custom logging application using the onboard AT45D DataFlash.

AtmelCorporation have announced two additions to their SAM G series of ARMCortex-M4-based MCUs. The two latest models are designated the SAM G54 and SAM G55. They feature high performance (up to 120MHz), low-power (102 µA/MHz in active mode, down to 5 µs wake-up) and tiny outline (as small as 2.84 x 2.84mm). Both are targeted at IoT applications and include all the features of the current SAM G family of devices including an Atmel | SMART ARM Cortex-M4 MCU + FPU (floating point unit) together with integrated sensor fusion algorithms.

Build a cheap and simple full software controlled step-up (boost) converter to drive a LED string of 10 LEDs. LEDs are used as string to light up a acrylic engraved plate placed in a holder (also made out 5 layers of lasered black acrylic glas). Step up is from 5V to about 30V, current regulated to about 20mA.

An app note from Atmel, digital sound recorder with AVR and DataFlash (PDF!):

This application note describes how to record, store and play back sound using any AVR microcontroller with A/D converter, the AT45DB161B DataFlash memory and a few extra components.
This application note shows in detail the usage of the A/D Converter for sound recording, the Serial Peripheral Interface – SPI – for accessing the external DataFlash memory and the Pulse Width Modulation – PWM – for playback. Typical applications that would require one or more of these blocks are temperature loggers, telephone answering machines, or digital voice recorders.

Although not officially released until December we were able to get a glimpse of Atmel corporation’s SmartConnect SAM W25 module at electronica 2014. This small module has been designed for use in IoT edge node applications. Edge nodes are parts of the IoT infrastructure where information interacts with physical events; these devices might, for example be inputting information from sensors or outputting control actions. The nodes also need to adapt the information to and from the network and provide data security.

Use a $4 microcontroller to launch web pages with the push of a button over serial I/O.. by Elliot Williams @ makezine.com:

A microcontroller is a self-contained, but very limited computer — halfway between a computer and a component.

The top reasons to integrate a microcontroller into your projects are connectivity and interactivity, and one easy way to get your microcontroller talking with the outside world is standard asynchronous serial I/O. Many devices can communicate this way, from wi-fi routers to GPS units to your desktop or laptop computer. Getting comfortable with serial I/O makes debugging your AVR programs much easier because the AVR can finally talk to you, opening up a huge opportunity for awesome.
