Re: ESP32-Cam and SD Card

Same results... when I have a servo on 16 the board just reboots with the Guru Meditation error. When I have a servo on 12 then I get unwanted servo movement whenever one of the following happens: - Flashlight LED flashes - Camera takes a picture - SD card is accessed/written All three of those even...

Re: ESP32-Cam and SD Card

I need serial, so 1 and 3 are out. 0 works fine, so that's good for one of the two servo motors. If I have a servo on 16 then camera fails to detect and the unit just reboots in a loop with a Meditation Guru error. If I have a servo on pin 12 then the servo moves randomly whenever the camera takes a...

Re: ESP32-Cam and SD Card

So after some tedious testing and investigation it looks like with the camera AND SD card enabled there is only really ONE gpio that's left usable with no side effects, IO0 (which is also used to put the board into flash mode but once it's running then you can use it as a standard GPIO). I could als...

ESP32-Cam and SD Card

I posted recently about some issues with an ESP32-cam module and servos and you guys were a great help. They're working great and I'm making progress with my project, but now I'm running into an issue with the built on SD card slot. My first issue is that it looks like the SD card uses most of the r...

Re: ESP32Cam and Servo Control

Thats more or less what I though... What I ended up doing last night, and this seemed to work, was to use a double headed USB cable from an older USB hard drive. This let me draw power from two usb ports but still only need ONE connection going to the ESP32 and servos. I then moved the servos draw o...

Re: ESP32Cam and Servo Control

So just a followup, now that I've got the camera working with the servo I wanted to add a 2nd servo. However no matter what I do, as soon as I add the 2nd servo the unit just starts endlessly rebooting with brownout warnings. I've tried various USB cables, various power sources, etc. So far no matte...

Re: ESP32Cam and Servo Control

I think I resolved it. It looks like I just need to specify higher numbered timers for the servos. I wasn't able to get the servos to work using timers 1 or 2, but 5 seems to work fine.

ESP32Cam and Servo Control

I'm sorry if this is the wrong forum to ask this in. A friend of mine gave me an ESP8266 a few months back and now I'm hooked no making gadgets and devices of all kinds. I recently bought several ESP32 boards and 2 ESP32Cam boards. I'd like to use the ESP32Cam to be able to control it's own Pan/Tilt...
