@@ -42,6 +42,52 @@ Each peripheral supporting condition for this BSP is as follows: | |
| | GPIO | Support | | | ||
| | UART | Support | Using LUATOS_ESP32C3 development board requires connecting serial port to USB chip UART0_TX and UART0_RX (such as CP2102) | | ||
| | JTAG debug | Support | ESP32C3 usb-linked development boards can be debugged | | ||
| | WIFI | Partial support | There are currently some problems, such as `rt_mq_recive` cannot be used in ISR, etc., and we are still trying to solve it | | ||
| | BLE | Partially supported | There are currently some problems, such as running errors caused by the same `PC` and `SP` pointers after `NimBLE` is started for a period of time | | ||
| | GDBStub | Support | You can use the GDB provided by ESP-IDF by turning on the `BSP_ENABLE_GDBSTUB` switch, which will enter GDB mode after a chip error | | ||
|
|
||
| Note: | ||
|
|
||
| 1. WIFI and BLE cannot be enabled at the same time. When using the BLE driver, be sure to turn off the `RT_USING_WIFI` and `LWIP` switches in `menuconfig`. In addition, due to limited personal abilities and lack of debugging equipment, there are problems with the operation of WIFI and BLE drivers. If you can solve it, please contact me [[email protected]](mailto:[email protected]), I will be grateful. | ||
|
|
||
| 2. The BLE driver only supports `NimBLE` and is provided by the `bluetooth` component in `esp-idf`. To use the BLE driver, please refer to `bsp/ESP32_C3/packages/ESP-IDF-latest/examples/bluetooth/nimble` Sample program, please note that the `esp_timer_init()` function must be called to initialize the clock driver before calling the `NimBLE` related interface. | ||
|
|
||
| One way to run the BLE sample is to add the sample program to `scons` compilation and call the clock initialization program and sample program entry in `bsp/ESP32_C3/main/main.c`. | ||
|
|
||
| ```c | ||
| int main(void) { | ||
| ... | ||
| #ifdef BSP_USING_BLE | ||
| esp_timer_init(); //Call clock initialization program | ||
| app_main(); //Call the BLE sample program entry | ||
| #endif | ||
| ... | ||
| } | ||
| ``` | ||
| 3、 Regarding the use of the GDBStub component, please see [ESP-IDF official documentation on GDBStub](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32c3/api-guides/tools/idf- monitor.html?#gdbstub-gdb), currently I have provided a debugging script `esp32c3.gdb`, the specific usage method is as follows. | ||
| ```sh | ||
| wcx@tim ~/rt-thread/bsp/ESP32_C3 esp32 ± sudo riscv32-esp-elf-gdb # Enter gdb debugging | ||

| | GPIO | 支持 | | | ||
| | UART | 支持 | 使用LUATOS_ESP32C3开发板需要在UART0_TX和UART0_RX连接串口转USB芯片（如CP2102）| | ||
| | JTAG调试 | 支持 | ESP32C3采用USB方式和PC链接的开发板可以调试 | | ||
| | WIFI | 部分支持 | 目前存在一些问题，例如不能在ISR中使用`rt_mq_recive`等，还在尝试解决中 | | ||
| | BLE | 部分支持 | 目前存在一些问题，例如`NimBLE`启动一段时间后`PC`和`SP`指针相同导致运行错误 | | ||
| | GDBStub | 支持 | 通过开启`BSP_ENABLE_GDBSTUB`开关即可使用ESP-IDF所提供的GDB，其会在芯片出错后进入GDB模式 | | ||
|
|
||
| 注： | ||
|
|
||
| 1、WIFI和BLE不能同时启用，在使用BLE驱动时注意在`menuconfig`中关闭`RT_USING_WIFI`和`LWIP`开关。另外由于个人能力有限且缺乏调试设备，WIFI和BLE驱动运行都有问题，如果可以解决联系我[[email protected]](mailto:[email protected])，本人感激不尽。 | ||
|
|
||
| 2、BLE驱动仅支持`NimBLE`，并且由`esp-idf`中的`bluetooth`组件提供，使用BLE驱动可以参考`bsp/ESP32_C3/packages/ESP-IDF-latest/examples/bluetooth/nimble`下的样例程序，注意在调用`NimBLE`相关接口之前要调用`esp_timer_init()`函数初始化时钟驱动。 | ||
|
|
||
| 一种运行BLE样例的方案是将样例程序加入到`scons`编译并在`bsp/ESP32_C3/main/main.c`中调用时钟初始化程序和样例程序入口。 | ||
|
|
||
| ```c | ||
| int main(void) { | ||
| ... | ||
| #ifdef BSP_USING_BLE | ||
| esp_timer_init(); //调用时钟初始化程序 | ||
| app_main(); //调用BLE样例程序入口 | ||
| #endif | ||
| ... | ||
| } | ||
| ``` | ||
| 3、关于GDBStub组件的使用，文档见[ESP-IDF关于GDBStub官方文档](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32c3/api-guides/tools/idf-monitor.html?#gdbstub-gdb)，目前个人提供了一个调试脚本`esp32c3.gdb`，具体使用方法如下。 | ||
| ```sh | ||
| wcx@tim ~/rt-thread/bsp/ESP32_C3 esp32 ± sudo riscv32-esp-elf-gdb # 进入gdb调试 | ||
