It would help if I could find the c code for gpio_matrix_in and gpio_matrix_out. I have searched the esp/components folder and cannot find the source code for these functions. They are not in gpio.c. Where is that code?WiFive Posts: 3529 Joined: Tue Dec 01, 2015 7:35 am Re: ...

I had previously been using IO Mux/GPIO Matrix without Bundle and writing directly to the wts/wtc registers in C and was getting 60ns. If the nops are added to the Deticated/Bundle technich it will also be 60ns. Thanks for the info posted above, it was very helpful.6...
The example: examples\peripherals\gpio\matrix_keyboard does not compile. There seems to be a problem with the Dedicated GPIO Configuration. One of the error messages is: DEDIC_GPIO_INTR_NONE' undeclared I ran idf.py set-target esp32c3. Did I miss something in memuconfig?
There are so many different sources for interrupts in the ESP32 interrupt matrix. The Interrupt Matrix embedded in the ESP32 independently allocates peripheral interrupt sources to the two CPUs’ peripheral interrupts. It does accept 71 peripheral interrupt sources as input. And it generates 26 peri...

- UART configuration types have been moved to `esp_hal::uart` (#2449) - `spi::master::Spi::new()` no longer takes `frequency` and `mode` as a parameter. (#2448) - Peripheral interconnections via GPIO pins now use the GPIO matrix. (#2419) ### Fixed Expand Down 544 changes: 32...
