Re: PicoTTS Text-to-Speech component
Hi CityHunter71! I hope you'll have fun experimenting with PicoTTS! You'll have full control over the audio buffers if you wish, so you can tinker as much as you'd like. I did find that I ran low on CPU cycles if I tried to both sample and generate speech at the same time, but I haven't had time to ...

PicoTTS Text-to-Speech component
Hi all, For quite some time I've been hoping Espressif would provide a TTS engine for English as well as Chinese. It's all well and good to be able to call out to services like OpenAI's TTS, but to me on-the-edge speech interaction needs to function without Internet connectivity. We already get exce...

Re: MQTT in IDFv5 - where is user_context?
For anyone else running into this issue, as pointed out to me on the github issue*, what has happened is that the mqtt library has moved its event notifications from its own callbacks over to regular esp_event notifications. So, the functionality still exists, but is now via esp_event. *) https://gi...

MQTT in IDFv5 - where is user_context?
Hi, I'm looking at porting an mqtt client implementation from IDFv4 to IDFv5, but I've run into what seems to be a big issue. Previously*, it was possible to set a "user context" pointer when initialising the client, and that pointer would then be handed back in each event. This followed the typical...

Re: Minimum supply voltage?
No, it's not something we'd be comfortable making assumptions on based on tests across a small sample. We ended up not using the ESP32 in the end.

Minimum supply voltage?
We would like to run ESP32 modules on a 2.4-2.7V supply. The ESP32 data sheet's pin list mentions that the chip itself can work down to 2.3V, the Espressif website claims 2.2V in the chip overview, and a post by John Lee here earlier suggested it was actually down to 2.0V. However, the data sheet's ...

Re: Cannot Start Task in ISR
Nope, no need from my direction. It was a point of curiosity since our (NodeMCU) event post function most certainly is used from ISRs (and uses the ...FromISR() versions).

Re: Cannot Start Task in ISR
@ESP_Sprite On that note, I saw that the default implementation of esp_event_send() uses xQueueSendToBack() rather than xQueueSendToBackFromISR(). Does that imply that esp_event_send() should never be called from an ISR, or are the queues safe regardless?
