Cypress CY7C65211 can be flashed only from Windows with a dedicated Cypress utility due to its unique flash file format. Fortunately, after some bargaining with Cypress I got a Linux utility that is licensed under LGPL and free (as speech _and_ beer). It can flash special, decoded versions of flash files that can be produced with a special Windows decoder executable that I can't provide with TinI/O because it's not GPL'd (actually it's not even licensed!) and isn't released to the public (yet). Instead the TinI/O package includes 2 already decoded flash files that should satisfy the needs of a typical user. Their names are:
- `5-5_decoded.cyusbd`, that provides 5 input and 5 output ports
- `3-3cs_decoded.cyusbd`, that provides 3 input and 3 output ports, plus a CapSense button with its dedicated input.

## 3.2 A little more detail on the flash files
_Here is a detailed description of the flash files configurations for the curious and other developers. It contains a lot of technical details, that aren't particularly useful in a typical TinI/O use case. A stripped-down version of the table below can be found at the end of the previous chapter "3.1 Flashing the chips"_
TODO Make a big ol' able with them config's
The flash files that are included with TinI/O don't have a Linux-compatible editor and therefore can't be tweaked to fit one's needs ideally. However, this can be done in a Windows environment using a dedicated program from Cypress. With it you can modify the chip's configuration without being limited to the premade flash files. However, some USB-related settings are and **have to be** the same regardless of the use case to ensure compatibility with TinI/O program.
