1. Prerequisite
This chapter provides the hardware and software prerequisites for using MCHPRT2 tool with the
ATWINC/ATWILC series and ATBTLC/ATSAMB series.
1.1 Hardware Prerequisites
This section provides the hardware tools that are required to test the RF system. ATWINC/ATWILC is
connected to the GUI using Aardvark™ or serial bridge. SAM-ICE™ is used to connect ATBTLC/ATSAMB
to GUI.
1.1.1 Aadvark I2C Host Adapter
Aardvark I2C/HCI Host adapter is used to interface PC via USB to I2C pins of ATWINC/ATWILC. The
same is shown in the following figure. For more information, refer to http://www.totalphase.com/products/
aardvark-i2cspi/.
Figure 1-1. Aardvark I2C/HCI Host Adapter
1.1.2 USB - UART Converter
This USB-UART converter (MCP2200) Breakout Module) will be used to interface PC to the UART DTM
interface of ATWINC3XXX, ATBTLC1000 and ATSAMB11 devices. Any generic USB-UART converter can
also be used.

1.1.3 JTAG Emulator
The AT91SAM-ICE is a JTAG emulator designed for ARM® core based MCUs and MPUs. It is used to
program test firmware. For more information, refer to http://www.microchip.com/DevelopmentTools/
ProductDetails.aspx?PartNO=at91sam-ice
Figure 1-3. AT91SAM-ICE JTAG Emulator
1.2 Software Prerequisite
1.2.1 Serial Bridge Connection (ATWILC/ATWINC)
MCHPRT2 GUI can be operated without the Aadvark tool with the help of serial bridge application from
Atmel Studio. In the GUI, instead of I2C select UART. Enter the valid Com port, baud rate and click Init to
start evaluating the RF test system. For more information, see the Serial Bridge Application Note.
1.2.2 MCHPRT2 GUI Tool
The MCHPRT2 tool allows the user to easily configure, evaluate and test an RF system. It simplifies the
effort during the early stage of development. The later sections have a detailed explanation on how the
tool is used to test the RF system.

1.3 UART/I2C Pin Details
Connect the UART or I2C to PC, and power on the ATWINC/ATWILC/ATBTLC/ATSAMB. Ensure that
ATWINC/ATWILC/ATBTLC/ATSAMB is in the right test mode with the correct pins.
The following table provides the I2C connection for ATWINC/ATWILC 1XXX and 3XXX series.

BT_TXD NA NA Pin 8 Pin 14
BT_RXD NA NA Pin 9 Pin 15
Connect the J-Link and power on the ATBTLC/ATSAMB-ZR series. Connect the BT_TXD and BT_RXD
lines to the UART input pins of an USB-UART converter.
The following table provides the J-Link connection for ATBTLC/ATSAMB series. Pin 41-49 is ground
exposed paddle; it must be soldered to system ground.

Note: MCHPRT/MCHPRT2/HCI_Command tools have DTR enable or disable function on UART.
For example:
SAMB11 Xpro board serial port setting is different, which only supports the following conditions:
serialport.DtrEnable = true;
serialport.Handshake = Handshake.RequestToSend;
serialport.RtsEnable = true;
In MCHPRT/MCHPRT2/hci_command tools DTR must be enabled.

It is mandatory that the ATWINC/ATWILC chip is in the right bootloader state for establishing connection
from GUI through I2C. To do that, the host MCU must power-up the ATWINC/ATWILC chip and then
perform the reset sequence as defined in the figure Power-up/down Sequence (ATWINC/ATWILC). This
is done very easily from the host MCU by calling the nm_bsp_init() and nm_bsp_reset() function. The
code snippet for the same is as shown below,
int main(void)
{/* Initialize the board. */
system_init();
/* Initialize the BSP. */
nm_bsp_init();
nm_bsp_reset();
while(1) {
}
}
1.4.2 Power-up/down Sequence (ATBTLC/ATSAMB)
The power-up/down sequence for ATBTLC/ATSAMB is shown in the following figure. The timing
parameters are provided in following the table. For SAMB11, ensure that the steps referred in Appendix
A5 Erase and Program SAMB11 are followed before establishing connection with MCHPRT2 GUI.
