*Dear All,* I hope this message finds you well.
I am currently working on a project using the ESP32C6 and find myself in need of an additional UART, bringing the total to three UARTs. Initially, I considered implementing a UART using bit-banging; however, after reviewing the documentation, I discovered that a low power UART option is available, which seems to suit my requirements. At first glance, adding this UART does not appear to be overly complex. However, I am encountering an issue related to a missing configuration: The UART configurations on the ESP require two parameters that I am having difficulty understanding: .txsig = U1TXD_OUT_IDX, .rxsig = U1RXD_IN_IDX, Could someone please explain what these parameters represent? Upon examining the gpio_sigmap.h file that references the ESP32C6, I noticed that there isn't a similar parameter available for use with the low power UART. How should I proceed in this case? Any guidance or assistance you can provide would be greatly appreciated. Thank you in advance for your support. *Best regards,* -- *Felipe Moura de Oliveira* *Universidade Federal de Minas Gerais* Linkedin <https://www.linkedin.com/in/felipe-oliveira-75a651a0> <https://twitter.com/FelipeMOliveir?lang=pt-br>
