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?

Re: ESP-IDF 1.0 Release plan
@ESP_iggr Regarding the interrupt allocation, I would much prefer to have you get that into master sooner rather than later, regardless of whether it's 1.0 compatible. My alternative is pretty much rolling my own and ignoring whatever you might actually provide later, because by then it'll be too mu...
