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: ...

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...
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...
Also tried to redefine #define USBPHY_DM_NUM 19 to an other pin in the first line in my .ino file, hoping it will reroute the GPIO matrix accordingly, but this didn't help either. avrguru Posts:1 Joined:Thu May 16, 2024 5:41 am ...
1.首先下载友善之臂Friendarm的开发包Matrix,并编译 apt-get update && apt-get install git git clonehttps://github.com/friendlyarm/matrix.git 2 . 针对NanoPC T3修改common.h, common.c两个文件 可能T3比较新,官方的开发包并没有包含对T3的初始化的支持,所以需要修改这两个文件 ...

- 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...
