@Dan, thanks for the note and for being a pioneer with all of us in this community. I feel like we're all trying to learn this stuff together and it's nice to have a sense of camaraderie.
There's a lot of challenges learning Synergy, e2 Studio, and the boards. After reading your comment, I had a new insight. You may want to want to contact @jcasman about borrowing an SK-S7G2 kit. We may be able to get Renesas to sponsor a few kits.
The primary reasoning behind this idea is that there's more tutorials from Renesas for the SK-S7G2, including blinky as part of the SK-S7G2 Quick Start Guide.
The original strategy of using the S3A7 IoT Fast Protyping Kit as a platform to explore IoT concepts with the Renesas IoT Sandbox is still valid. However, I think some people quickly go through Smart Chef Demo and Smart Garage Demo and then want to customize the LCD panel for their specific data. Or, they may want to add their own set of sensors.
As the S3A7 IoT Fast Protyping Kit is a new board, there are not as many tutorials to learn Synergy. Most of the tutorials focus on the Renesas IoT Sandbox and use the existing binary for Smart Chef. The tutorials that get into Synergy assume prior knowledge.
A gentler path would be to go to SK-S7G2 GUIX "Hello World" after the SK-S7G2 Quick Start Guide. This is not usable with the S3A7.
On this path, I used this video for the SK-S7G2, but it's fully usable with the S3A7.
After that, I think that Getting Started with the Weather Panel Application would be good.
Although I haven't gone through the Weather Panel Application tutorial, I believe it is the basis for the SK-S7G2 With AMS Sensor and Connected Weather Demo.
After those four tutorials, I think it would be easier to swing back to the S3A7 and get something awesome going for a full project. For example, the S3A7 Smart Chef Demo with Cloud-Driven GPIO would then look more feasible. To be honest, I feel we made an error in directing people to that tutorial prior to more basic tutorials for e2 Studio and Synergy.
We may need to migrate some of the SK-S7G2 tutorials to the S3A7 IoT Fast Prototyping Kit boards. A short-term strategy might be to get access to an SK-S7G2. @jcasman and I might be able to secure 5 units from Renesas for people like you that are interested in digging more into Synergy.
We're all learning and hopefully having fun in the process.
