## 3.1 Flashing the chips
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.
And they provide the following configurations:
| _parameter_ | _value in `5-5_decoded.cyusbd`_ | _value in `3-3cs_decoded.cyusbd`_ |
|-------------|---------------------------------|-----------------------------------|
| parameter | value in `5-5_decoded.cyusbd` | value in `3-3cs_decoded.cyusbd` |

_Note: Not all of the information here is neccesary to know when using TinI/O.
For a stripped-down version refer to the next chapter, "Using TinI/O"_
Please notice that flashing of these files isn't the only way of configuring chips. They can be also customized with the Windows utility. The important thing is that you should
configure the USB settings as described in the table above.
## 3.3 Flashing with the `cy-config` utility
The flash files I covered in the previous chapter can be flashed with the `cy-config` utility that installs with TinI/O. The utility is text-based. It can be used by running `cy-config`.
