"Since Altera launched a new series of Max 10 FPGA devices, the focus on Max 10 has been constant in the market. If you count down the existing development kits based on Max 10 FPGA in the market, there are really many, such as Max 10 neek kit with rich functions, Altera Max 10 FPGA Evaluation Kit in portable pocket laboratory, Odyssey max10 sensor development kit for IOT, etc, These boards have their own characteristics, and the onboard functions also cover different user groups to a certain extent. Today, aiban.com will recommend another FGPA development kit based on Max 10 devices - the deca development kit obtained from iResearch electronics.
As we all know, the max 10 FPGA series has greatly increased the logic resource density (up to 50K logic units) on the basis of the previous generation of max series products. It also integrates resources such as embedded processor soft core, DSP module, DDR3 storage controller, analog module and so on. Compared with the max 10 FPGA itself, which we are already very familiar with, Let's focus on what functions this development kit of deca will carry.
The packaging box of deca development kit itself is very large, and the internal accessories are also very rich, including:
A deca development board
A WiFi ble expansion board
One 800W pixel camera module (ar0833)
One Ethernet cable, two MINIUSB cables
One 5V / 2A power adapter
A quick start note
Interestingly, the WiFi ble expansion board equipped with the deca development board is compatible with the expansion interface of bbblack, which makes it easier for many engineers familiar with the open source hardware board of bbblack. In addition, the ar0833 800W pixel camera module adopts the latest Mipi interface used in current electronic products, such as mobile phones and tablets, This greatly facilitates the engineers to transplant the camera function platform in the future, which is very good.
In addition to the supporting accessories, the deca development board has many onboard functions, including Ethernet function, analog input, audio circuit, various sensors, touch keys, etc., which is convenient for engineers to develop various simple to complex multimedia project applications based on the prototype DIY of deca development board.

Among the currently known Max 10 FPGA products, in addition to the onboard 10m50 FPGA product, there are also product series for low-end application markets such as 10m02 and 10m04 with less resources. For details, please refer to the figure below.
In addition, let's take a look at the expansion board compatible with bbblack expansion interface provided in the development kit.
There are mainly two wireless module circuits on the expansion board, Ti based cc3100 WiFi and Ti cc2650 ble.
Ti's cc3100 is mainly composed of WiFi network processor and power management subsystem. The Wi Fi network processor subsystem includes a unique Wi Fi internet-on-a-chip and a dedicated ARM MCU. Of course, this ARM MCU does not act as a host control, but is mainly responsible for Wi Fi and internet protocol processing. In this way, there is no need for external microcontroller to handle these things, It greatly facilitates the selection of external MCU by engineers, or directly realizes the expansion of existing projects through SPI interface and UART interface, such as the current expansion on deca development board, which is connected through SPI signal, which is quite flexible.
The main features of cc3100 are as follows:
802.11 B / g / N RF, baseband and media access control (MAC), Wi Fi driver
Base station, access point (AP) and Wi Fi direct mode
TX power: 18.0 dBm@1 DSSS，14.5 dBm@54 OFDM
RX Sensitivity: 95.7 dBm@1 DSSS，74.0 dBm@54 OFDM
Application data throughput: UDP: 16mbps, TCP: 12mbps
VBAT Wide voltage mode: 2.1 to 3.6V

After understanding the characteristics of the deca development board, we officially launched the video game and connected the camera module and expansion board to the deca motherboard. It fits very well and looks very tall.
Before power on, we need to understand the whole power supply system of the lower board.
It can be seen that the whole deca development board has seven different working voltages. Applications requiring high current are realized through the power module and internal integration of DCDC, while low current applications use LDO. For a development board, the power supply system of deca is very complex.
The power adapter matched with the board is 5v-2a output. After power on, the board runs the built-in factory program. It seems that the effect of breathing lamp is realized by changing the lighting frequency of led through PWM.

The development of deca development board needs to use Altera's EDA tool quartus prime. Since Max 10 is the latest product launched by Altera, the corresponding EDA version needs to be more than 14.0.2 to support, and quartus prime after 14.0 needs a 64 bit system to support. At present, the latest version on the official website is 15.1 (quartus prime) 15.1 instructions for use). Deca development kit is equipped with rich routine resources, including materials provided by Youjing and Altera's online design store resources.
Engineers can select appropriate application routines according to their own needs, such as the CapSense function on the board, which is realized through cypress's capacitive touch sensor chip cy8cmbr3102 and internally connected through I2C signal.
We can compile and download through Altera's EDA tool quartus prime.
Similarly, you can directly download and view the routine through the script program written in the routine application, as shown in the following figure.
After the download is completed, the LED can be lit as long as you put your finger close to or touch the touch key position on the deca development board.

Let's also take a practical look. Since there are detailed design guidelines for building routine applications in the wiki, this article will not repeat the steps one by one. If you have needs, you can click here to view them. Load WiFi ble routines.
The development board runs WiFi AP mode, and we can search for a hotspot named dallaslogicwifi.
Connect the computer in the author's hand to the WiFi hotspot of the development board and open the website mysimplelink.net.
At this time, we can control the LEDs and sensors on the deca development board through the buttons under the tab bar on the website.
