Human Machine Interface (HMI) platform for the rapid release of customer products. The core of yG (pronounced, "sig") is Renesas SynergyTM a comprehensive and integrated software-based microcontroller platform. FDI adds the Synergy platform to its GUI hardware, systems and production expertise. The end result is a sum of high-quality products that provide a robust and proven source for GUI and HMI solutions: yG = Renesas Synergy+ GUI The yG-S7G2 Modular Development Kit for the System on Module is the gateway for beginning Renesas SynergyTM projects. The yG-S7G2 Modular Development Kit is compatible with FDI's yG Modular Development LCD Kits but can be used independently as a lower cost option for those embedded applications without the need for a touch screen display. FDI offers low cost customization services for customer specific hardware, software or packaging applications at volumes of 500 units or more. 1.2 ESD Warning The YG-S7G2-MDK is shipped in a protective anti-static package. Do not subject the module to high electrostatic potentials. Exposure to high electrostatic potentials may cause damage to the boards that will not be covered under warranty. General practice for working with static sensitive devices should be followed when working with the kit. 1/30/2025 Copyright ©2025, Future Designs, Inc Page 5 of 26 YG-S7G2-MDK 1.3 Renesas Synergy S7G2 Microcontoller Block Diagram User's Manual Figure 1: S7G2 System Block Diagram 1/30/2025 Copyright ©2025, Future Designs, Inc Page 6 of 26 YG-S7G2-MDK 1.4 yG-S7G2 SOM System Block Diagram User's Manual Figure 2: YG-S7G2 Kit Block Diagram (4.3" display shown) 1/30/2025 Copyright ©2025, Future Designs, Inc Page 7 of 26 YG-S7G2-MDK User's Manual 1.5 Requirements The YG-S7G2-MDK requires a carrier board with a 200-pin SO-DIMM socket. The socket should have the key at the 1.8V location. The CARRIER Board from Future Designs provides this socket and should be utilized to develop your application for initial verification. Each yG development kit includes: · yG-S7G2 System on Module (SOM) · Renesas Synergy Software Platform · Carrier Board · 5 VDC, 2.3A North American Power Supply · USB and Ethernet Cables · Segger ARM Cortex-M Mini-JTAG debugger and cables · Optional LCD Carrier Board · Optional 4.3" or 7.0 PCAP Touch Screen LCD 1.6 yG-S7G2 SOM Power Requirements The power requirement for the YG-S7G2-MDK is 5V DC Center Positive 2A Power Supply. Getting Started 2.1 Setting up the Hardware The SOMDIMM should be inserted into the DIMM Socket as shown below and then locked into place by pushing down to the Carrier Board. Ensure the SOMDIMM is inserted completely into the socket prior to locking. The socket utilized on the CARRIER Board is rated for a minimum of 25 insertions. 1/30/2025 Copyright ©2025, Future Designs, Inc Page 8 of 26 YG-S7G2-MDK User's Manual Figure 3: SOMDIMM Insertion The following are step by step instructions for setting up the hardware. 1) Make sure you have a SOMDIMM board plugged into the CARRIER board at J1. 2) Verify the LCD Interface ribbon cable connects the LCD CARRIER board to the CARRIER (J7) board. 3) With the power off, plug the 5V center-positive Power Supply into 5V (P5) of the CARRIER board. 4) Connect an RJ-45 Ethernet cable to the ETHERNET (J5) interface of the CARRIER board. 5) Plug in a female-to-female DB9 serial cable between PC and RS232 (P4) on the CARRIER board. 6) Insert a USB drive. 2.2 Demonstration Software Insert a formatted USB drive into the YG-S7G2-MDK boards and connect them to your PC using an Ethernet cable. In your PC, set a static IP address on the PC to be on the same network (IP=192.168.0.x with Subnet mask=255.255.255.0). Once connected, the YG-S7G2-MDK demonstration software will deliver you to a web page at the address https://192.168.0.180. Thread counts will automatically update or you can click on "System Variables" to force an immediate update. Use the 7 ThreadX tasks outlined on the web page to update the system variables. 1/30/2025 Copyright ©2025, Future Designs, Inc Page 9 of 26 YG-S7G2-MDK User's Manual Figure 4: ThreadX YG-S7G2-MDK Demonstration 1/30/2025 Copyright ©2025, Future Designs, Inc Page 10 of 26 YG-S7G2-MDK User's Manual yG-S7G2 SOM System on Module Board Components 4.1 ARM Mini-JTAG J2 The yG-S7G2 SOM uses a JTAG connector based on a 2mm header.
