FPG-EYE hardware and software
The FPG-EYE is a development board produced by Evidence S.r.l.. The board core is based on Lattice Lattice XP2-17 fpga. This board can be used as a standard fpga development board or as a mico32 soft-core platform.
On FPG-EYE can be found on the following devices:
|25Mhz crystal oscillator|
|Serial Flash 4Mib|
|Leds and switches|
And as Optional:
|Colors CMOS Camera|
|RF Transceiver Module|
More technical informations you can get on Evidence FPG-EYE page.
The FPG-EYE board is provided with a programmed demo application inside. The demo application is hosted by a Mico32 platform. Furthermore you can download FPG-EYE software packet. The packet contains:
- Evidence custom camera component (MSB component with binary netlist).
- Evidence custom serpar_io component (MSB source component).
- Binary external flash bootloader.
- Python bootloader interface script.
Following a brief description of these software components.
Evidence custom camera component
The camera (mico32_camera) is a wishbone component developed by Evidence S.r.l.. Once imported in MSB's Available Components, you can use it in yours platform designs. Mico32 camera comes with an Erika driver with all API you need for your applications. You can find code examples of mico32_camera API use on [downloadable applications]. Otherwise you can write yours personal driver. You find all needed information to do that on Mico32_camera: Writing drivers based on mico32_camera page.
Evidence custom serpar_io component
This is another Evidence S.r.l. custom component. Like other custom component, before use the serpar_io in yours platform, you have to imported in MSB's. It is, essentially, a parallel serial converter. The processor writes a datum on out register of the serpar_io component, that serialize it out to a 74hc595 (serial to parallel shift register) device. Similarly, serpar_io can get a serialized datum from 74hc165 (parallel to serial shift register) and put it on his in register, so the cpu can read it. The serial to parallel shift register enable/disable devices power supply and leds on the board. On other hands the parallel to serial shift register reads switches states on the board. You can find code examples of serpar_io use on [downloadable applications].
