Re: FabGL

You don't have to use anything from the Arduinocade project, just the code to read from the NES controller: #include ... #ifdef _use_gamepad_nes byte state = 0; byte nes_state = 0; byte NESreadButtons(void); byte NESshiftin(void); void NESstrobe(void); #endif ... #ifdef _use_gamepad_nes nes_state = ...

Re: FabGL

The GPIO's INPUT_PULLUP are very small on an ESP32, so it is most convenient to use a splitter controlled by an additional GPIO. splittersimple.gif splitter.gif The USB is only for power supply. Using a NES or SNES controller, as I mentioned before, is as simple as using the GPIO for CLK, Reset and ...

Re: FabGL

Is there any way to attach any gamepads to the VGA32? Here you have the use of an Atari DB9 controller with the WEMOS D1 R32 board: https://github.com/rpsubc8/ESP32TinyChip8 PlacaWemosD1R32cvbsmod.gif If you want to use a TTGO VGA32 v1.x board, the easiest way is to use the Mosfet Sot23 of the PS/2...

Re: FabGL

A long time ago I made a port of the uzem emulator to the ESP32 with VGA, but the result was very slow, less than 19 fps: https://www.youtube.com/watch?v=ajBJ0d2dqbY So I chose to port the API in C, getting real time, no problem: https://www.youtube.com/watch?v=ovIUlSzXTU4 Instead of using fabgl, I ...

Re: Arduinocade -

Thank you very much. The most difficult work has been done by rossum. I just started from your code and made several modifications, adapting them to what I needed. Thanks also for the gconvert tool, I'll take a look at it calmly. The utility to play mp3 through DTMF commands sent by arduinocade, I h...

Re: About to wire up the non-color version of the Uzebox

Thank you very much for answering my questions.
Is there any possibility of using another xtal, for instance 14,318 MHz and using a trick, so you can double the speed at 28.636 MHz?
The cost of shipping the xtal of 28.636 MHz are very high. :o

Re: About to wire up the non-color version of the Uzebox

For black and white version (without using the AD725), what if you change the 28.61818 MHz oscillator by another 28,322 MHz oscillator, it should make any changes to the kernel code? What problems can result in the image and sync?
What other oscillator values ​​are possible?
Greetings.
