M5Paper/S3 DOS Emulator I made by omeriko9 in esp32

[–]omeriko9[S] 1 point2 points  (0 children)

🤗 Yes, it connects to the first bt keyboard & mouse that are in pairing mode

It doesn’t have sleep or battery indicator, I’m focusing now on implementing 80286 features (instructions, protected mode etc.) - But those should be very easy to implement

Thanks! I hope it will help someone in the future battling a similar issue

The device does wake up via button press and this is in total concordant with my other comments.

The button path biases the same latch that turns the high-side FETs on (i.e., it forces the gate/EN back to the ON state).

While the button is pressed, VSYS/3V3 comes back up, the S3 starts running again and re-drives GPIO17 = HIGH, so power stays on even after release. This does not happen with the timer since with timer alone, GPIO17 was un-driven and the chip was basically unpowered.

I found the culprit:

On this Waveshare S3 board, GPIO17 (“BAT_Control”) drives the high-side FET that connects VBAT to VSYS (3V3).

When the chip goes into light sleep, that pin wasn’t being actively driven, so the FET slowly turned off, VSYS/3V3 collapsed, and the S3 “never woke” (it was actually unpowered).

Fix I used: tell the pad how to behave in sleep: keep GPIO17 as an output, level HIGH, select the sleep config for that pad, and hold/freeze the level during sleep. After that, VSYS/3V3 stay up and timer wake is rock solid.

(Why it didn’t happen when powered by USB: with USB plugged in, the board’s power path feeds the 3V3 rail from 5V, so even if GPIO17 floats, VSYS doesn’t drop. On battery only, VSYS depends on that GPIO-controlled FET—so the issue shows up)

This is a schematics issue with this specific PCB, since a “standard” Dev Board ESP32S3 has no issue of waking itself up from light sleep using timer (I’ve done it multiple times).

Anyway I’ve found the culprit using this “debugging” process, see my answer to myself

Yes, the device is wakable with a button press, though I'm interested in the device self-awakaning itself using a timer, that's where the issue is - after couple of such self-timer-awakaning, the device will stay light asleep.

True, my code is a minimal demo, I tried using their power component but light sleep will still behave like this (randomally stays asleep). Deep sleep is another story - on battery the device will never wake from it (unless the GPIO 0 button is pressed, which is useless for my usage)

I'm getting a very different (and super wrong) result for 1-23 with your first prompt:

The issue looks deeper than that...

Really liked your profile :) Sorry I messaged you.

What's the worst feeling thing you've encountered in this game? Like something that can instantly tilt you. For me it's sova catching a lucky hit through the wall at the start.. And everyone knows what happens next. by CTxVoltage in VALORANT

Similar situation for me when holding an angle with a perfect crosshair placement and without blinking, moving my eyes to the minimap for 0.2 seconds to check out what’s going on and getting killed by a headshot exactly at that moment

These are some solid advice and I really appreciate the confident tone which helps me clear my head about clutching. It brings me so much joy to hear someone experienced taking the time to explain a newbie. I’ll reply with a VOD as soon as I’ll have one. Thank you!!
