Board data: Yingpeng Feijia Control Evaluation Board EVB-T335 Download
BBBLACK has a raspberry sect in the open source hardware, a large reason is that its onboard core chip -ti's AM335X series application processor, relies on stable and reliable, versatility, etc., this in the industry Applying an extremely wide chip is almost one of all the "must-have courses" for industrial control board companies.
Free application for EVB-T335 industrial control board
In the traditional industrial control equipment, stability has been in the first place, and with today's technology is getting more mature, in the pursuit of stability, it is necessary to make factors such as performance, function, and price, which allows the threshold in the industrial control. A lot. In China, companies that can do and do a good job in industrial control are also a lot, such as Mir Technology, Yingji, Fei Ling, Yingpeng Fei, etc., each has its own characteristics, this time, the pavilion network has got Ying Peng A Ti AM335X (Cortex-A8) series processor program is launched - Evb-T335, this piece has an industrial control board with the BBBLACK's classroom chip?
EVB-T335 Evaluation Board
EVB-T335 evaluation board supporting device is very complete, the interface scaled on the board is basically equipped with related wires, saves the cost of the user's second purchase or DIY. What is more worth mentioning is that the evaluation board that has been taken is also equipped with a 7-inch LCD screen module with a resistive touch screen, which is convenient for users to develop the board, which looks very good.
The EVB-T335 evaluation board is divided into a bottom plate and the core plate COM-T335. The bottom plate is an extension of core board functions and peripheral interfaces, and the core panel can be used as a project product development, which is very flexible and convenient.
EVB-T335 Development Board Features:
TI company Cortex-A8 AM3352 processor, 800MHz frequency
Onboard 512MB SDRAM, 2GB EMMC
Second Road Gigabit Ethernet, does not support IEEE1588; two high-speed USB HOST

EVB-T335 Based on the field of industrial control, the EVIC is particularly strengthened, such as expanding 6 serial ports and common industrial control bus CAN, and the board is extended to two Gigabit Ethernet ports, which invisible The difference from the general industrial control board, in addition, the high-precision RTC circuit supports the expansion of the WiFi module, supports the audio circuit, and some features of their onboard.
Take a look at each peripheral interface of the Myb-AM335X backplane.
Power / WiFi Antenna / USB HOST / Ethernet / Audio Interface
Since the TI AM3352 application processor selected by the EVB-T335 evaluation board, it integrates two Ethernet Mac. Here is the design of adding two Ethernet PHY to implement communication communication, compared to single Ether The network port, the advantage in special applications can be embodied, such as connecting to other devices while connecting the Internet, and the AR8035 Ethernet PHY supports the Gigabit network transport protocol, supports the RGMII interface.
MicroSD / serial port
RTC Button Battery / Touch Screen Interface / I2C / LCD / LVDS Interface
COM-T335 core board
Let's take a look at the core module COM-T335 of the EVB-T335 onboard.
The core module COM-T335 is the control brain of the entire EVB-T335 evaluation board. The process is also more than the bottom plate, and the 6-layer PCB board, the stamp hole design, 144Pins, the relative bottom plate is also more smart, only 40 * 40mm size, not as good as a bank card.
The COM-T335 core board mainly mounted the core application processor AM3352, 2GB EMMC 512RAM SDRAM, TI power management chip, and RTC chip, and its hardware structure is shown below.
The core board AM3352 belongs to an application processor in the TI AM335X series, based on the ARM Cortex-A8 kernel, 800MHz frequency. Although TI is a ARM depth partner, it is not much based on A8 kernel. It is: OMAP35X and AM3X series, OMAP with TI's own DSP core, suitable for high-speed computing equipment; and AM3X series It is an industrial grade chip, the price is cheap, the industrial parameters are stable, and there are more domestic and foreign use.
Ying Pengfei selection TI AM335X series application processor as the core of the industrial control board is also due to the market trend, the AM335X series is relatively rich in image, graphic processing, peripheral, such as Ethernetcat, PROFIBUS industrial interface options, and AM335x series Products can choose a stronger application processor when adding functions to implement compatible, without frequent modification, which is invisibly reduced by developers' cost.
The following table is some of the features of the TI AM335X series of products.
Therefore, the user can complete the COM-T335 core board as a package completed SOC, determine the 144PIN foot signal to implement, DIY to go to your project, such as a POS machine application with COM-T335 core board DIY .
POS machine application
Another example is true for medical monitor applications.
Monitor application
Of course, more human machine interactions are not under words.
Human-machine interaction application
Used
Basically, the characteristics of Yingpeng Fei EVB-T335 development board, we actually look at it, here the author will use the liquid crystal module of the set of 7-inch with resistive touch screen as a video output of the board, to ensure the normal start and operation of the system Need to make some settings.
1. Connect the interface of the resistance touch screen, the signal of the resistance touch screen is not integrated with the interface of the LCD screen, and is additionally connected.
2. Make sure the system starts configuration hopping J1 in the OPEN state, the board will start from EMMC (J1 is in a closed, the board can be activated from the MicroSD card).
Plug in the 5V / 2A power adapter, turn on the power switch to power it, the EVB-T335 development board is built into the Linux system, when the board is running, the yellow Run LED light on the core board will keep flashing, an upper power except Loading U-boot is the core board of Yingpeng Fly.
System loading
After entering the system, Ying Peng flew to the user to prepare two test methods, one is the QTDemo test mode, and the other should be a factory-factory function test mode.
Qtdemo test
Engineering test mode
The engineering test mode is basically facing, and the functions of the board can be tested.
In addition to this, we can also operate the Linux system with the supplied serial forward wireway.
For example, use the ECHO implementation to light the LED.
In addition to the test of the LED, the author also tested the USB interface, the network port, serial port, microSD and other functions. It can be used normally. About the test method and the official information of the development board support, the love board will also release it later in the forum. On board related information for users to download. Overall, for users who have demand for industrial control applications, the "full-featured" EVB-T335 industrial control board "full-feature" EVB-T335 industrial control panel launched by Ying Pengfei is indeed worth a try.
summary
Introduced the function and basic use of Yingpeng Fei EVB-T335 development board, rich industrial-grade peripheral function and supporting information is the flash point of Yingpengfei. From the current situation of the market, most of the TI AM335X series products are more widely used in the field of industrial control, and the performance is relatively stable and reliable. If the user is based on the POS machine, the monitor, human-machine interaction, etc. mentioned above and those itself BBBLACK design-related applications but cannot meet the final product needs of the company / users can try the COM-T335 core modules provided by Yingpeng Fei, perhaps you will bring you a surprise. Love board network forum has now opened the free trial opportunity for EVB-T335 industrial control board, and users need to apply for free, send the door!
