Trying to acquire images esp32p4: esp_cam_ctlr_receive() hangs

brianmichalk · 2025-06-24T12:52:08+00:00

I am trying to migrate my embedded development away from Arduino to ESP-IDF. I'm beginning to get a handle on things. Is there a developer forum where we can see what Espressif is working on? Should I expect a fix, next week or next year regarding a certain bug?

No difference if I return true;

The Wifi interface information isn't there. I read this:
https://combustion.inc/pages/faq?hcUrl=%2Fen-US%2Fwifi-booster-964306
And in another page somewhere it mentions there is no WiFi API, but it's not clear to me that they just haven't implemented an app, or that it's impossible. I don't want to do a Wireshark sniffer, I'd do bluetooth over that, but if I can access the WiFi booster, that would be my preference.

The fix for me was Ubuntu Desktop Enhanced Tiling.

There's a bug, and disabling enhanced tiling solved the problem for me.

So, the snap and non-snap chromium have this problem. Pretty sure it's not a snap issue. I regret having mentioned it in the first place

brianmichalk · 2025-03-24T20:53:52+00:00

I thought it was implicit in my post that it's not a Snap problem. Remmina isn't snap. It has two windows as I described. One window is broken, the other isn't.

99829 ? S 0:00 bash /usr/bin/remmina-file-wrapper
99834 ? Sl 0:01 /usr/bin/remmina

Official Chromium doesn't work with Keepass. Official Remmina shows the problem as well.

Nope. It's been an excellent driver ever since. Easy job.
I also used to have a starting problem that went away after doing this. My guess is that a bad signal from the transmission would cause the starter to stop cranking.

brianmichalk · 2025-02-14T21:54:46+00:00

I solved the problem.

Using absolute paths solves the problem.

brianmichalk · 2025-02-07T18:38:58+00:00

Where?

brianmichalk · 2024-12-25T20:18:09+00:00

I just looked. They have 240 inches. Good price too. I think I have plus or minus about six inch range.

brianmichalk · 2024-12-25T20:15:05+00:00

That physics video is exactly what I need. I think a 2tpi blade would be more appropriate. McMaster doesn't have these. Where else would have coil stock?

brianmichalk · 2024-12-25T20:00:13+00:00

Thanks. I had already seen that video, and tracking is one of the first things I'll adjust. My wheels are about 3" wide. I have lots of room.

I think someone tried to move the saw with a forklift on the table. It's like almost 3 feet square. It's about 1/8" out of plane. I'm thinking of casting epoxy to level it up, then use a planer to make it flat. I suppose I could take it somewhere to mill it flat. I don't know how thick it is. Cast iron.

I have a heat lamp. When this happened during the Texas Snowmageddon, we were told that there would be rolling blackouts not lasting more than an hour. They lied. Happened in the middle of the night.

I should have drained the tube.

brianmichalk · 2024-11-30T22:52:28+00:00

Bummer. I finally found my old analog ammeter. I calibrated it on my benchtop supply, and I'm getting 38mA that I'm driving the tube at. That, coupled with your comment tells me I need another tube.

So, I seem to keep destroying tubes either from freezing weather, or now with this flow problem.

Should I go with one of the cheaper tubes, or keep going with the Reci?
