Re: Can someone explain my oscillating touch readings?

Turns out it was an incredibly noisy 12v DC adapter. Even plugging it in a few metres away made the touch sensor go wild. Values are very clear and smooth as soon as it is unplugged.

It's a dirt cheap one from eBay, I'll be replacing it one from a reputable brand and checking again.

Can someone explain my oscillating touch readings?

I don't know much about AC, EMI, etc. I have a simple program on a basic custom ESP32 WROOM breakout board reading a touch pin and printing out the value via an ESP-PROG. When I am not touching the pin, it maintains an expected stable value ~1200. However, when I hold my finger on the pin, there is ...

Re: Esp32 ULP/RTC time drift

Possibly because you're not compensating for ULP program run time. If it's rounding up after 67 loops, and we know that means it's accumulated an additional second, then that's about 15ms per loop. That's possible given that you're doing I2C stuff. It would also mean that it should 'skip' another se...

Re: That is a somewhat curious forum here...

There's also this (expect it will be merged soon): https://github.com/espressif/arduino-esp32/pull/3900 On-topic, I'm probably about 1000:1. I've learned a lot from the issues and solutions discussed between other people, especially when it's some component/peripheral/thingy I've never tinkered with...

Re: Error loading jQuery from SPIFFS / AsyncWebServer

% is used to identify placeholders in AsyncWebServer so it will become a mess if there are other % characters in the file. Define something else for TEMPLATE_PLACEHOLDER (eg. `). See https://github.com/me-no-dev/ESPAsyncWebServer/blob/fc66fae6a96091143b873834231554aa013e084f/src/WebResponseImpl.h#L62

Re: can't configure http client timeout timer.

I had a PR here that implements it (but you should consider it very WIP and not production-ready): https://github.com/espressif/esp-idf/pull/3791 esp_http_client uses that internally to connect. If you want different timeouts for connection and send/receive with esp_http_client then you have two opt...

Re: can't configure http client timeout timer.

No, unfortunately, LWIP hasn't implemented a simple per-connection connect timeout. There are a few more TCPIP config options exposed in IDF 4.0 but they won't help much in this case. I share your frustration.
