Espressif4_4_1 精简便携式 : VSCode1.61_嵌入式便捷式_含必备插件:

一、将压缩包文件解压到C盘根目录

1. 将[settings.json]，复制到"C:\Users\用户名\AppData\Roaming\Code\User"

二、 安装VScode插件 Espressif IDF

三、编译例程，并调试

1. 使用VScode打开 C:\prog\Espressif\esp-idf\examples\peripherals\gpio\generic_gpio
3. 选择对应芯片型号，再执行编译



4. 
   



6. 编译完毕后，执行烧录



7. 
   



9. 打开观察窗口，查看串口log



10. 
    

第二种：更换任意盘符

1. 便携式vscode v1.69.1,集成嵌入式常用插件（解压即用） ​​下载​​：
2. 便携式Espressif v4.4.1，解压后，编写环境变量即可。​​下载：​​

需要添加的环境变量如下：

IDF_PATH                   D:\prog\Espressif
IDF_PYTHON_ENV_PATH        %IDF_PATH%\tools\python_env\idf4.4_py3.8_env
IDF_TOOLS_PATH             %IDF_PATH%\tools


PATH添加如下：
手动一次添加
%IDF_PATH%;
%IDF_TOOLS_PATH%\tools\idf-python\3.8.7;
%IDF_TOOLS_PATH%\tools\xtensa-esp32-elf\esp-2021r2-patch3-8.4.0\xtensa-esp32-elf\bin;
%IDF_TOOLS_PATH%\tools\xtensa-esp32s2-elf\esp-2021r2-patch3-8.4.0\xtensa-esp32s2-elf\bin;

%IDF_TOOLS_PATH%\tools\dfu-util\0.9\dfu-util-0.9-win64;
%IDF_TOOLS_PATH%\python_env\idf4.4_py3.8_env\Scripts;

在末尾;直接添加
%IDF_PATH%;%IDF_PATH%\tools;%IDF_TOOLS_PATH%\tools\idf-python\3.8.7;%IDF_TOOLS_PATH%\tools\xtensa-esp32-elf\esp-2021r2-patch3-8.4.0\xtensa-esp32-elf\bin;%IDF_TOOLS_PATH%\tools\xtensa-esp32s2-elf\esp-2021r2-patch3-8.4.0\xtensa-esp32s2-elf\bin;%IDF_TOOLS_PATH%\tools\xtensa-esp32s3-elf\esp-2021r2-patch3-8.4.0\xtensa-esp32s3-elf\bin;%IDF_TOOLS_PATH%\tools\riscv32-esp-elf\esp-2021r2-patch3-8.4.0\riscv32-esp-elf\bin;%IDF_TOOLS_PATH%\tools\esp32ulp-elf\2.28.51-esp-20191205\esp32ulp-elf-binutils\bin;%IDF_TOOLS_PATH%\tools\esp32s2ulp-elf\2.28.51-esp-20191205\esp32s2ulp-elf-binutils\bin;%IDF_TOOLS_PATH%\tools\cmake\3.20.3\bin;%IDF_TOOLS_PATH%\tools\openocd-esp32\v0.11.0-esp32-20211220\openocd-esp32\bin;%IDF_TOOLS_PATH%\tools\ninja\1.10.2\;%IDF_TOOLS_PATH%\tools\idf-exe\1.0.3\;%IDF_TOOLS_PATH%\tools\ccache\4.3\ccache-4.3-windows-64;%IDF_TOOLS_PATH%\tools\dfu-util\0.9\dfu-util-0.9-win64;%IDF_TOOLS_PATH%\python_env\idf4.4_py3.8_env\Scripts;

三 使idf支持c++17

x\Espressif\tools\cmake\build.cmake

四 不定长接收串口数据

x\Espressif\components\driver\uart.c

//read any size, only added two line to fucntion uart_read_bytes, marked with mk

    int len_tmp;
    if(xSemaphoreTake(p_uart_obj[uart_num]->rx_mux,(portTickType)ticks_to_wait) != pdTRUE) {
        return -1;
    }
    while(length) {
        if(p_uart_obj[uart_num]->rx_cur_remain == 0) {

            } else {
                //When using dual cores, `rx_buffer_full_flg` may read and write on different cores at same time,
                //which may lose synchronization. So we also need to call `uart_check_buf_full` once when ringbuffer is empty
                //to solve the possible asynchronous issues.
                if(uart_check_buf_full(uart_num)) {
                    //This condition will never be true if `uart_read_bytes`
                    //and `uart_rx_intr_handler_default` are scheduled on the same core.
                    continue;
                } else {

                    return copy_len;
                }
            }
        }
        if(p_uart_obj[uart_num]->rx_cur_remain > length) {
            len_tmp = length;
        } else {
            len_tmp = p_uart_obj[uart_num]->rx_cur_remain;
        }
        memcpy((uint8_t *)buf + copy_len, p_uart_obj[uart_num]->rx_ptr, len_tmp);
        UART_ENTER_CRITICAL(&(uart_context[uart_num].spinlock));
        p_uart_obj[uart_num]->rx_buffered_len -= len_tmp;
        uart_pattern_queue_update(uart_num, len_tmp);
        p_uart_obj[uart_num]->rx_ptr += len_tmp;
        UART_EXIT_CRITICAL(&(uart_context[uart_num].spinlock));
        p_uart_obj[uart_num]->rx_cur_remain -= len_tmp;
        copy_len += len_tmp;
        length -= len_tmp;
        if(p_uart_obj[uart_num]->rx_cur_remain == 0) {
            vRingbufferReturnItem(p_uart_obj[uart_num]->rx_ring_buf, p_uart_obj[uart_num]->rx_head_ptr);
            p_uart_obj[uart_num]->rx_head_ptr = NULL;
            p_uart_obj[uart_num]->rx_ptr = NULL;
            uart_check_buf_full(uart_num);
        }
    }

    xSemaphoreGive(p_uart_obj[uart_num]->rx_mux);
    return copy_len;
}
