The lamps and filters have a longer life than other lamp-based projectors, with a lamp life of 10,000 hours in normal mode and 17,000 hours in Eco Mode. It's lamp-based (not laser) and boasts a low total cost of ownership (TCO). I would like to know if this is related to calculating jpeg data units.The most affordable device in Epson’s signage projector range. I got fed up with messing with it and just look at several images, wrote down all the file sizes and the magic bytes, converted everything to binary and hammered away at ANDing ORing bitshifting until I forced a formula that worked. Here is the formula for those last 3 bytes: int iSize = bImage.length īaHeader = (byte) ((iSize > 7) | 0x80) I was able to solve this, but I would like to know why this works. The projector only supports the use of RGB565 jpeg images inside the data send. I've read lots of stuff about jpeg and am still digesting much of it but I think if I knew what was required to calculate data units, I'd find my mystery 3 bytes. So it seems that the 3 bytes have something to do with data units. I then changed the 3 bytes to 00:b5:80 (incremented the middle one by 0x30) 1b - All white (RGB565) image 1024x768 - filesize 12915 - 22 full rows and 4 blocks.Ģb - Color (RGB565) image 1024x768 - filesize 58577 - 7 rows and 22 blocks. Here are some examples: 1a - All white (RGB565) image 1024x768 - filesize 12915 - 4 blocksĢa - Color (RGB565) image 1024x768 - filesize 58577 - only 3 blocks ![]() Also the smallest image size I can send to the projector is a 3w x 1h which correlates with my first two images show below. Anything less and the image will not project. ![]() I have found what seems to be a base line by setting those last three bytes to 80:85:00. Here is a screen shot of a partial capture with the 3 bytes highlighted: If I strip off that header, I can view the image. In the data send, a jpeg image is sent with a header attached like this. I can connect and send images captured through packet traces from a Windows machine with a driver but cannot create an acceptable image. I have an Epson Ex5220 that doesn't have a linux driver and have been trying to work out communication through wifi.
