Re: axi_axi_hdmi problems in directfb supplied examples
Hi, The driver implements the FBIOPUTCMAP ioctl. But since the framebuffer is in truecolor format (which means you can specify the color for each pixel individually) setting a palette makes no sense...

Hi, Sorry I forgot to mention that you need to replace the '$1' with the radio station frequency you want to listen to, e.g. 89.3. - Lars

View ArticleRe: Need help implementing CVBS and HD/SDI output from VGA / LVDS
Dave, I have some follow up questions regarding the ADV8005. 1) Can this part accept LVDS input (I don't see native capability), or do you have a recommended chip to convert 720p/1080p LVDS into...
View ArticleRe: Need help implementing CVBS and HD/SDI output from VGA / LVDS
Hi Mike, 1) Nope, and we have no LVDS to HDMI or LVDS to TTL converter. A small FPGA could almost certainly do LVDS to TTL though.2) It can't read settings from an EEPROM directly-- it always has to be...

Re: Need help implementing CVBS and HD/SDI output from VGA / LVDS
Hi Dave, Which would yield better results (or easier setup, cheaper hardware maybe?) through this chip, in your opinion; LVDS to HDMI, or LVDS to TTL? My LVDS port has 2x 4-channels. Mike
View ArticleRe: EVAL-ADV7619-7511 having interop problems with Blu-rays
Hi Lin- I think delay caused by DVI is the consequence, not the reason. The reason is lack of device authentication within 100 ms. HDCP 1.4 spec says “The HDCP Transmitter must not read the R0 ' value...
