the i2s has a maximum data rate it supports
the base clock can be like 40MHz
but the pipeline itself is a bit finicky
it simply stops working at certain clock rate that's around 20Mhz
DVI specs have lowest clock at 25.175 MHz
Any link for an FPGA upscaler?
What would you recommend as a good ESP32 dev board to start out with? And what kind of toolchain to support it?
would an external serializer IC mean the esp32 would only need 2.5175Mhz gpio speed for DVI?
@Nicolas Tremblay the new arduino FPGA board support hdmi.. I would look into that and clone it
@Dan Maloney tkae something with many pins that's cheap and goes on a bread board. Arduino IDE with ESP32 integration is the simplest tool chain
I like TTGO boards, a lot of them include battery charging on board and are small enough to embed in even small portable projects. See #SatNOGS On Air O
@erik pax not sure.. could be :-) you know any ones that does that?
This project is about the design of an 8-bit/16-bit nostalgia motherboard using currently in-production parts, and designed to interface primarily with modern peripherals. Features based on modern peripherals: - 2 Atari or Sega-style joystick ports. Should work with 6-button Genesis controllers, and many compatible controllers are currently in production.

@morgan I am using them, too. but they always want shipping :-D
What I was wanting to do is use the ESP8266 to control a RX5808 Analog receiver, 8 input 1 output ic switch and generate a NTSC output to switch the video output to. an overlay would also be nice using something like a MAX7456 chip.. The problem is 2 fold CPU power and enough CS lines..
yeah... I just buy a dozen or so at a time
also, custom WROOM/WROVER is pretty straight forward, in the future I'll be making more of my own custom devboards
without doing something tarded like hang a bunch of 328P's off it via I2C and have them manage the individual SPI's..
heard of the Frog Board ?
@erik pax is it serializing using the fpga?
@andrew.michael.johnson :-D sounds neat... multi processing at its best
@Nicolas Tremblay nice.. that's even cheaper than the one from aliexpress that I got
I think the serializer is a sepperate chip
I have to look into it, that might be the best hint I got so far :-)
what I'm currently in is checking out ICs that do VGA conversion to HDMI
analog devices has some encoders
I have a handful of NodeMCU's I use with breadboards... Have done a lot with arduinos, STM32 and TEENSY stuff but have not had the time to take the ideas I have in my head and start programming and breadboarding hardware for it yet.
but they are dicks since you have to have an HDMI license to get the ICs from them
Really? That seems wrong.
ADV7513 is the IC I have hhere now
actually you are not allowed to use the word HDMI if you are not licensed
I think you can just fake the HDMI signal over DVI
the smallest license you can get is 5k/year and somewhat like 1$ /device
What are you supposed to call it then?? XD
