I would like to be able to output VGA from AVR projects. VGA LCDs (used) are incredibly cheap. I don't need incredibly high resolution.
The main limit is cost, if the project is close to $25, then I might as well just add a rasPi. I think the best approach is to use SRAM to buffer a bitmap and then sync that up with the monitor.
This sram chip would work. There are some "tsop adapter" relatively cheap.
This might work well with double buffering - two ram chips one in read mode, one in write mode and a single bit to switch.
