Quote from: bmp02 on July 02, 2019, 10:14:29 PMPlease note the chip on the programmer needs to be flashed with firmware and fuse bytes. To do that, I bought the Micro USB Tiny AVR ISP / USBTinyISP Programmer (this one: https://www.ebay.com/itm/Micro-USB-Tiny-AVR-ISP-5V-ATtiny44-USBTinyISP-Programmer-For-Arduino-Bootloader/222053881584). It's 1.86$ including shipping, not too bad huh.Then download this driver (https://learn.adafruit.com/usbtinyisp/drivers) and the AVRDUDESS Gui (http://blog.zakkemble.net/avrdudess-a-gui-for-avrdude/) to flash firmware and fuse bytes.

Quote from: SilentEyes on March 03, 2021, 08:02:54 AMHi provato,I know it has been forever since I posted in this forum lmao.First and foremost, How would I be able to wire the switch to my oscillator? I was thinking more like I take NTSC/3.3v from one pin of the GPU and then PAL/GND from another pin of the GPU and somehow wire them to the outsides of the switch and then the middle to the oscillator? My PU-7 does seem to only have 1 input. If you're saying that I need to wire the input of S0 the switch, I wouldn't really understand how to do that. I dunno, you're better than me at this. It seems that the newer models are easier cause they have two inputs that you can link to a second oscillator. In this case, I was thinking of wiring a 53.20mhz oscillator from a PAL ps1 that's broken, but I don't know where S0 would be on a hardwired pu-7. I know this is a lot lmao, I have lots of questions. Please let me know.Thanks!

Quote from: Monkeyball on March 18, 2021, 06:03:52 PMI've had a DFO installed on my PAL 5552 model PS1 and I am having a strange issue with the console.My TV normally switches between NTSC / PAL modes automatically but on this occasion it is having issues syncing to the PS1 signalThe strange bit is the console is a PAL model with DFO but PAL games are not syncing correctly and if the TV does manage to lock onto the signal the colours come out wrong NTSC games are working normally though.I had the DFO installed so that I could have the games work with the correct colours in PAL / NTSC using composite cable.What do you think is going on?It works on a more modern TV KV-32FQ70U but not my primary retro tv SONY KV-A2942UThe TV in the video is in service mode and it gives an example of the problemhttps://www.dropbox.com/s/nq7zpme04u4qn9e/VIDEO0286.mp4?dl=0In the second video you can see it a bit clearer without the black rolling lines picked up by the phone camerahttps://www.dropbox.com/s/mj74auwwcfi40i8/VIDEO0287.mp4?dl=0I'm thinking maybe its an issue with the installation or the DFO itself as I understand it was made with modern TV's in mind?Maybe an older CRT needs different clock frequency timing?Btw what was the result of installing a 50/60hz switch on the 1002 model? I'm guessing that installing a switch will allow the TV to sync properly
Quote from: provato on March 19, 2021, 08:03:37 AMIt's not a mod for modern TVs only. It should work perfectly fine with ntsc 4.43 and pal 4.43 capable CRTs. Your monitors are indeed capable of both ntsc and pal (looked up the manuals).Use an RGB scart PS1 cable (to rule out subcarrier frequency problems) and see if the problem persists.If it does, then most probably it's an installation or a clockpro code problem.Which clockpro hex file have you written on the cdce**** chip, and which such chip are you using?

PU-8 SCPH-1002 model. Here's a picture of your board.Close to the GPU, there is an xtal marked "53.20", which outputs 53.2 MHz. Remove it from the board using a hot air gun while being careful to not remove any of the other SMD components that are close to it. That will reveal 4 solder points. Now it's time to install the DFO: solder the 3v3 line to the upper left pad, solder the GND line to the lower right pad, solder the CLK output to the upper right pad and finally solder the S0 line to pin 7 of the Sony CXA1645 video encoder chip.You can also follow this procedure on PU-18 boards (SCPH-550x), although it uses a different video encoder, so you should solder S0 to a via that leads to pin 157 of the GPU instead.
