RCA to VGA using FPGA for Raspberry Pi
Hi all.. Shortly received my Raspberry pi... i took my byte... :)
I don't have HDMI capable display or an RCA monitor when i received the device..
But the eagerness was so high to think about an RCA video to VGA conversion, since my PC monitor is VGA capable only and was immediately available with me.
I have an Altera DE2-115 FPGA board with Cyclone IV FPGA. It is a future perfect development board with a bunch of multimedia capabilities and large I/O options (still lacking HDMI ).
It have a RCA Video In plug. It also have a VGA output connector. So i thought of connecting Rasp pi RCA output to the DE2-115 board. And VGA out of DE2-115 to my PC monitor. The starter CD with DE2-115 have a TV Box Demonstration program. Refer to the DE2-115 User manual (page 55). Loaded the .mcs file of TV Box program to Cyclone FPGA. Connected and powered Raspberry Pi.
Voila... The raspberry fruit logo and boot messages started scrolling up.. and finally Raspberry Pi desktop was on my PC monitor.
This is not a cost effective solution because an FPGA development board can cost you thousands.. but still it reminds about the powerful capability of building your custom hardware inside a FPGA chip on the fly and which in-turn reduces a huge time of prototyping and testing.
and if your are seriously looking for a VGA solution for Raspberry Pi, then buy an HDMI to VGA converter.
