Debug with serial

You can only print things to debug for this. If you wanna set break point, checking registers etc, use another debug method.

ref. and code: https://github.com/portapack-mayhem/mayhem-firmware/pull/2111/files

usage

1. Include the async msg header in your file

#include "usb_serial_asyncmsg.hpp"

if err happend after including it, maybe try not to include it but still using it (we are trying to settle the headers to prevent circuit including but it need sometime)

2 print things in your code and it will appear on serial.

void FileManBaseView::push_dir(const fs::path& path) {
    std::string test_string = "test string:";
    UsbSerialAsyncmsg::asyncmsg(test_string);
    std::string test_string111 = "abcdefghi";
    UsbSerialAsyncmsg::asyncmsg(test_string111);

    std::string test_path_label = "test_path:";
    UsbSerialAsyncmsg::asyncmsg(test_path_label);
    UsbSerialAsyncmsg::asyncmsg(path);

    std::string test_vec_label = "test_vector:";
    UsbSerialAsyncmsg::asyncmsg(test_vec_label);

    std::vector<uint32_t> test_vector;
    test_vector.push_back(1);
    test_vector.push_back(2);
    test_vector.push_back(3);
    UsbSerialAsyncmsg::asyncmsg(test_vector);

    std::string test_num_label = "test_num:";
    UsbSerialAsyncmsg::asyncmsg(test_num_label);

    uint8_t test = 254;
    UsbSerialAsyncmsg::asyncmsg(test);

    if (path == parent_dir_path) {
        pop_dir();
    } else {
        current_path /= path;
        saved_index_stack.push_back(menu_view.highlighted_index());
        menu_view.set_highlighted(0);
        reload_current(true);
    }
}

why not printing anything?

• make sure async msg lock is disabled.

asyncmsg enable

• make sure serial connected

help

• MayhemHub currently not support real-time serial command communication. Use others.

It’s possible that the object you are printing isn’t implemented yet (e.g. color obj). If you would like, feel free to implement it by editing usb_serial_asyncsg.cpp and hpp files.
