In 2015, Shanghai's CES exhibition once again proved the hot, and with the rise of smart hardware products, a variety of WiFi module programs have also become a hot frying of many manufacturers. This is not, ATMEL is also "going to" a development learning suite based on WiFi program - Winc1500-XSTK, mainly for the field of Internet of Things.
WINC1500-XSTK is the learning development kit of the Atmel XPlainedPro platform, including a SAMD21 XPLAINEDPRO motherboard, a WiFi module extension ATWINC1500, and an IO1 sensor extension board, as shown below.
Samd21 XPlainedPro motherboard and IO1 sensor expansion board everyone is unfamiliar, we have accessible in past evaluation, SAM D series MCU belongs to the ATMEL ultra low power series microcontroller products, based on ARM Cortex-M0 + processor, SAM D21 board is interested in reference to evaluation articles:
Simplified embedded system design - XPLAINED PRO development board equipped with ATMEL SAM D21
This article we focus on see the WiFi module expansion board in this development kit, as shown below.
Atwinc1500 XPLAINED Pro is similar to the other extension modules of Atmel, using standard 20pin extended interfaces, and the main devices on the expanded board are the WiFi modules of this model of Atwiinc1500-MR210PAM.
Atwinc1500-MR210Pa is a WiFi module optimized for low-power Internet access, with a working voltage of 2.7V to 3.6V, support IEEE 802.11 b / g / n, with a size of only 21.5mm * 14.5mm * 3.4mm. The module integrates power amplifiers, low noise amplifiers, switches, power management, and PCB antenna, which can be connected to the main controller via SPI and UART interfaces, which are as follows:
IEEE 802.11 b / g / n (1 × 1), up to 72 Mbps rate
PA and T / R switch, integrated PCB antenna
Treat outstanding sensitivity and range through advanced physical layer signaling
Support Wi-Fi direct connection and AP mode
Support IEEE802.11 WEP, WPA, WPA2, WAPI
On-chip memory management engine to reduce host load
4 megabits of internal flash memory and OTA firmware upgrade
SPI, UART and I2C as host interface
2 or 3-line Bluetooth coexistence interface
TCP / IP Agreement Stack (Client / Server) Application Socket
Network Protocol (DHCP / DNS), including security TLS protocol stack
In addition, we can also understand the wireless performance parameters of the Atwinc1500-MR210PA module through some WiFi modules on the market, as shown in the following table, the advantage is obvious, but there is a point in which the engineer pays attention to the ATWINC1500-MR210Pa needs external MCU.

After first understanding the characteristics of the Atwinc1500-MR210PA module, let's take a look at the actual usage. The Atwinc1500-MR210PA module needs to be used with the Atmel's XPLAINED PRO development board, as shown below.
Open the Atmel Studio6.2 IDE tool, if your version is too low, does not support Samd21 XPlainedPro motherboard, first need to upgrade.
We can see the Atwinc1500 XPlained Pro expand board, Atmel Studio 6.2 is not identified, what is going on? Look at the prompt, we need to go to Atmel Gallery to upgrade the expansion board plugin.
Open the Tool menu, find the extension manager, find the WinC1500 in many plugins for upgrade, after upgrading, we can load the corresponding routine officially upgrade the board and debug.

summary
Introduced Atmel's latest Atwinc1500 XPlained Pro WiFi module board and the use of SAM D21 development boards, in the era of rapid rise in the net network, an excellent WiFi module solution has become a hot flavor, atmel The launch of the Atwinc1500-MR210PA WiFi module is not only low power consumption, but also has high receiving sensitivity. It is more free to use other MCU platform to implement the expansion of wireless solutions. Interested to go to the Atmel official website to learn more, the recent love board network will launch this WiFi Develop a trial activity of the kit, please look forward to it.
