Re: IR receiver/transmitter for ESP8266?

Another question: so where does the ESP8266 fit into this equation? Is it also hampered with FreeRTOS under the hood in terms of software-driven interrupts?

Re: IR receiver/transmitter for ESP8266?

So I've got an ESP32-S with two UARTS at 62.5 and 202Kbps, with a hopeful but likely unrealistic <1ms realtime requirement, to mux both of those serial channels into a third UART operating at 460800. But after reading your other thread about soft interrupt issues with ESP32-S, I then went down the r...

Re: Timer with microsecond resolution

So is ESP8266 an option here? From what I understand it is not plagued with soft IRQ issues as ESP32-S?

Re: Timer with microsecond resolution

But RMT is write-only and beta status currently, correct?

Re: Timer with microsecond resolution

This thread makes me sad. I've been working on a design with three serial UARTs @ 57.6Kbps, 62.5 Kbps, and 202 Kbps speeds and ultra low latency / jitter requirement for the 62.5/202Kbps UARTS, using ESP32-S as the MCU running Micropython. Is this even doable with the ESP-32 given these soft interru...
