Hi,
I recently started to use my FEZSpider starter kit to try to build some mini project for my company, and I bought FEZHydra and Serial Cam L2 to use as an upgrade to the starter kit component. However, the code works in FEZSpider does not work with FEZHydra.
There are two problems,
- The touch panel becomes unresponsive. When using FEZSpider, the Glide button will stay pressed as long as I press it. However, with FEZHydra, it is not only hard to press the button, but the button will become “unpressed” in like 300ms (although the TapEvent will be triggered)
- The Serial Cam does not work after moving to FEZHydra. I found that the last block data of the picture was never sent out. I have attached a screenshot as a reference.
I am using NETMF 4.2 RTM QFE2 with the lastest GHI package (GHI NETMF v4.2 and .NET Gadgeteer Package (10-24-2012).zip)
