Guide: In the previous NXP LPC11U37 development kit, the characteristics and functions of the board OP-Marco have prelimated, today I open another mystery card GS1011mix.
Today, another mystery card GS1011Mix is opened.
The GS1011MIX card is exactly that it should be a WiFi module, provided by GainSpan. The OP-Marco board is required to show its function.
OP-Marco is perfect with GS1011Mix
Supporting interface, implementing data interaction
Match OP-Marco with GS1011MIX, the GS1011MIX board power hop is connected to the + 3V3 and the MCU side. At this time, the GS1011MIX board voltage will be provided by OP-Marco and does not require an external DC power supply.
Give the NXP LPC11U37 development kit, normal start
At this time, the NXP LPC11U 37 development kit will be used to start the function in the trial, and the SW5 key is pressed, the GS1011Mix WiFi module will initialize, when WiFi is initialized, the RGB LED will extinguish
At this point, open the WiFi of the phone or mobile device, use the Android system as an example, search the SSID WIFI hotspot with NXP_XXXX, confirm the connection
Download the corresponding app for NXP LPC11U37 development kits (temporarily only supporting Android system) and install, open the application, click Start, enter the IP address 192.168.240.1, click Bind, if the connection is successful, you can display the suite sensor collection. Related information.
The OFF switch in the software can control the switch of the RGB LED. At this point, in conjunction with the SW1 button, you can switch the display of different colors of the RGB LED.
Red
Green
Blue
When you open our installed app, you can see a "light bulb", at this time, the NXP LPC11U37 development kit is close to strong light source, "light bulb" will slowly brighten, and the mobile card can also see A three-axis movement to the gravity acceleration sensor.
A set of very interesting development boards, a very loved app, compared to the general development board, the NXP LPC11U37 development kit does have increased a lot of fun.
As we all know, we use the ultimate goal of the development board to debug development. Compared to the current popular development board, NXP LPC11U37 development kit does not have a plate debug module, but its performance is still a strong. The own SWD debug interface can be compatible with a lot of trial simulation.
If there is a LPC-Link2 debugging the emulation, it is convenient, it is fully compatible with the OP-Marco's SWD debug port.
If not, then tragedy, fortunately I have a U-Link2 in my hand, you can download debugging in your own simple DIY.
Ready to work
First we have to figure out the OP-Marco board SWD debug interface definition.
Secondly, if you want to pick up the SWD interface debug board, the signal line must be connected in addition to the power supply, the territory, and the RESET, SWCLK, SWDIO signal feet, which are 15.7.9 pins according to the standard 20-pin JTAG circuit interface.
After the interface is defined, the DuPont line is connected, power up and open the development tool Keil, set the corresponding emulator, select SW debugging
IDCODE that can read the device has a normal SW communication, this, you can select the corresponding code to perform Debug
Quite good development kit, NXP LPC11U37 is essentially non-a small Internet of Things system, hoping to divide a piece of tide in smart interconnection.
