Hello do you have contact details anywhere like email or twitter?

thanks

Please, if you express the reason why you need an additional communication channel (beyond this) we could find a way. I could reach you.

I saw your interest in video on esp32 and I was curious to know if you had seen this:

https://www.reddit.com/r/esp32/comments/gosbxg/esp_8_bit_atari_8_bit_computers_nes_and_sms_game/

The interesting thing being that it displays NTSC as well as PAL on composite video from esp32. NTSC has never been done before successfully.

My code works fine in NTSC. Please have a look at my fork of ESP32lib.

Do you also use the audio PLL to achieve NTSC, like esp_8_bit? What does your solution do different to ESP32lib to get NTSC? esp_8_bit also says it has very stable color PAL signal due to the audio PLL - curious to know if your code does this too?

I'm hoping there will be NTSC and Pal for FabGL one day because there a well documented development libraries and also the VT100 terminal on FabGL. At the moment it is only VGA.

Maybe one day the various solutions will merge in some way so all the best features of each are combined,

I am working in a highly portable code. Still not ready. Current public version ("advanced" branch): NTSC works very well (slow, but new upcoming version is fast and allows millions of colors). PAL needs more work. I will need to study what esp_8_bit does. For now, bitluni's lib with my extension is the only library capable of outputing to both VGA and composite. I you want details you can read the issues in bitluni's repo and see the changes I did in the commits (my commit comments aim to be self-explanatory and the diffs are incremental to be easy to understand). Do you have specific suggestions? are you willing to help and get involved in the development?

Mainly I'm interested because I'd like to write applications that can be displayed on analog TVs. For some reason I have collected about 20 old analog TVs (alongside a large vintage computer collection).

Do you have specific suggestions?

No, mostly I'm just curious about how and why the various solutions do things as they do. I just find video/VGA/PAL/NTSC on esp32 an interesting field. There's lots of great innovation - all the libraries seem unique in some way and each discover new and amazing ways to do things.

I made a comparison of each: https://www.reddit.com/r/esp32/comments/gpezk3/feature_comparison_of_esp32_graphics_sound_game/

I'm keen to do testing. I have TV's capable of NTSC and PAL.

Have you thought about trying it on the esp32-s2? The possible advantage there is that more PSRAM can be mapped into DMA addressable space which perhaps could make a larger frame buffer.

Do you have a repo with your new driver in it yet?

[Martin-Laclaustra]

Your help is welcome. Please refer to https://github.com/bitluni/ESP32Lib/issues/50#issue-618742128 where you will find all the information on the development. I do not have any esp32-s2. Have you tried bitluni's lib vga in it? You can try mine for composite (it is the same lib). I do not know how advanced the support for it in the arduino-esp32 project is. ... nor how different the registers to control I2S are. However, I have other ports in mind for the code first, but they will have to wait for now. I am closing this issue here as this is totally unrelated to CronAlarms.
