CC3200-LAUNCHXL Development Board Evaluation Report
[Copy link]
I am very grateful for the help of EEworld and TI. I couldn’t wait to open the package after receiving it. There was a USB notebook and a CC3200 red board in the package. It was great and I was very happy. . .
Nowadays, everything is connected, and the Internet of Things is applied in various products. Think about it, before the Internet of Things came out, every time we developed a product, after selling it, if your product has a bug, you need to take the product back and then upgrade it. Isn’t it very inconvenient? But if we apply the Internet of Things technology, when we find that the product has a defect, we can remotely upgrade the product we sold through WIFI or 4G, which saves time and effort, especially for overseas customers. You only need to upgrade it in the company with a click of the mouse. Of course, there are many aspects of the application of the Internet of Things. I will just give an example to illustrate.
In order to achieve remote upgrade, we first need to rotate a chip. When selecting a chip, we need to consider the following issues: actual functions, power consumption, applicability, cost, etc. After multiple comparisons, we finally determine the solution.
The one to be reviewed is the Ti CC3200 LaunchPad
The above is the unboxing picture of CC3200. The big one in the middle surrounded by the gold border is CC3200. I have marked the onboard resources in the picture. The first thing I did after getting the board was to download the manual and SDK package from TI's official website (this was actually my first time playing with it): Here are some descriptions from the official website:
Description
This Launchpad Wi-Fi reference design features the SimpleLink Wi-Fi CC3200 Internet-on-a-Chip solution with integrated MCU for Internet of Things (IoT) applications. This embedded Wi-Fi solution is a wireless MCU that integrates a high-performance Cortex-M4 MCU and peripherals, allowing customers to develop an entire application using a single IC. The CC3200 includes an M4 core running at 80MHz and offers up to 1MB of Flash options and up to 256KB of RAM options, providing flexibility to match your end application. Includes a rich set of peripherals including SPI, UART, I2C, I2S, SDMMC, 4-channel ADC, 4 PWM, and built-in power management. Powerful cryptographic engines such as AES, 3DES, SHA, and CRC allow your application to connect securely to the cloud.
With built-in wireless and Internet security protocols and on-chip security accelerators, the SimpleLink CC3200 solution delivers a reliable, trouble-free security experience for the IoT.
characteristic
Wi-Fi network processor with on-chip WLAN and TCP/IP stack
On-chip Cortex M4 80MHz processor allows custom APIs to be implemented on-chip
802.11 b/g/n station with fully integrated auto-calibrated radio, baseband and MAC
Advanced Wi-Fi connection manager that does not require host processor involvement
2 UARTs, 2 SPIs, camera, audio, I2C, 4-channel 12-bit ADC, 4 timers, 16-bit PWM, 27 GPIOs
Embedded encryption engine with 256-bit encryption technology and WPA personal and enterprise security features
From the above, we can see that this WIFI chip is quite playable.
Now start to power on. Since I am not in the lab, I cannot measure the power consumption at present, I can only power on and off.
Note: Due to the high power consumption of the board, if you connect the sensor at the beginning, the serial port of the notebook cannot carry the current, so you need to remove the sensor jumper pins J2, J3, and J4 on the board. The picture is as follows
