The Arduino VGA Shield will be, as the project name may indicate, an Arduino shield that outputs VGA video.
Project Status
Initial design phase, chipset selection, BOM assembly.
Chipset Options
- 4D Systems µVGA-PICASO-MD1 module ($54)
- Very expensive
- Some complaints about reliability
- Only talks RS232
- New 4D Systems uVGA-II(SGC) module ($49)
- Relatively expensive
- Only supports up to 800x480 (WVGA) @ 16bpp
- Very easy to interface with (via an I2C/SPI to RS232 bridge likely)
- Propeller chip with custom code ($8)
- Cheap
- Unsure how high resolution would be possible given generating VGA video from an MCU
- Custom FPGA solution ($?)
- More work than any other solution
- Similar cost to propeller chip, likely
- Off-the-shelf VGA controller chip
- The Epson S1D13506 seems promising, you talk to it and it has an internal RAMDAC to generate video.
- Supports LCD, VGA, and NTSC/PAL composite output
- Flexible bus to talk to the microcontroller
- Requires EDO DRAM, which isn't available anymore.
- The Epson S1D13517 might work, it's like the S1D13506 but takes SDRAM
- Supports up to 800x600 16bpp
- Only supports TFT displays, may be able to make it talk DVI though through timings/TMDS converter?
- The Epson S1D13506 seems promising, you talk to it and it has an internal RAMDAC to generate video.
- Project Peacock
- Hybrid CPLD/MCU solution, cheaper than using a softcore in an FPGA
- Would allow for an easy DVI shield too
