<div></div>

<div> </div>

<div><strong>2、初步应用</strong></div>

<div>将板子，接到电脑上，打开串口115200，显示日志</div>

<div></div>

<div>当前固件为：BW16 Combo-AT固件(固件号1879)</div>

<div>准备刷入：BW16最新版Combo-AT固件(固件号2179)</div>

<div>固件更新版本说明：<a href="https://aithinker.readthedocs.io/zh-cn/latest/docs/taobao/BW16/index.html">RTL87XX系列 — 安信可科技文档 (aithinker.readthedocs.io)</a></div>

<div> </div>

<div><strong>3、电路分析</strong></div>

<div>原理图：</div>

<div>BW16-Kit版本中接口Type-C对应串口0，引脚UART_LOG_RXD（PA8_LOG_RX0）、UART_LOG_TXD（PA7_LOG_TX0），操作AT指令不会发生冲突。</div>

<div>开发板只能选择通过Type-C或者通过UART_LOG_RXD、UART_LOG_TXD引脚接TTL模块的方法烧录新固件，完成固件升级。</div>

<div><span style="color:#3498db;">Flash默认2MB</span></div>

<div><span style="color:#f39c12;">原理图没什么问题，唯一的就是，板子上没有丝印啊，也没有丝印图，想改阻容不知道哪个是哪个~</span></div>

<div>  </div>

<div> </div>

<div><strong>4、固件更新</strong></div>

<div>刷入最新固件2179，</div>

<div>刷入教程和工具：BW16_V1.0和V1.2开发板下载更新固件指导手册：</div>

<div><span style="color:#1abc9c;">打开串口工具，选择对应的串口号，配置波特率115200,8,N,1，用16 进制显示：</span></div>

<ol>
<li>将开发板连接电脑</li>
<li>长按右边的按键Burn不松</li>
<li>按一下左边的复位按键</li>
<li>松开右边的按键Burn，此时模块进入烧录模式<br />
如果进入到烧录模式则电脑串口会不断接收0x15，则进入了烧录模式；<br />
</li>
<li>关闭串口助手的端口占用</li>
<li>打开ImageTool.exe 工具，Chip Select选择（8721D）<br />
</li>
<li>COM选择对应的串口号，波特率为1500000，open串口，下方会显示open successfully连接成功；<br />
地址0x8000000，Size：2048KB，刷入固件前点击erase擦除flash内原有的固件<br />
</li>
<li>点击erase擦除<br />
点击Browse选择最新的固件，可以分开刷入，也可以直接选择合并好的（2179）BAT_BW16_自定义_16Mbit_V4.18_P5.6.4_20230530.bin，地址0x08000000<br />
</li>
<li>点击Download进行下载，固件更新，完成后自动关闭串口<br />
<br />
</li>
<li>此时使用串口助手打开端口进行连接，log仍在输出0x15，<span style="color:#3498db;">点击复位，已为最新版本的日志，发送AT+GMR指令查看版本号，固件更新成功</span></li>
</ol>

<div></div>

<div><strong>5、AT指令点灯</strong></div>

<div>DEMO板的RGB5050三色灯分别接在了芯片的PA12/PA13/PA14脚</div>

<div></div>

<div>确认引脚在芯片上的位置，通过RTL8720DN的数据手册如下，发现PA12/PA13/PA14脚对应芯片的20/21/22脚</div>

<div></div>

<div><strong>①、设置IO管脚映射关系</strong></div>

<div><strong>AT+SYSIOMAP 查询或设置 IO 映射表</strong></div>

<div>命令：</div>

<div>AT+SYSIOMAP=<PinNumber>,<pin1>,<pin2>,...,<pinN></div>

<div><pinNumber>：要设置的 IO 总数。</div>

<div><pinxx>：模组 IO 引脚</div>

<div>（从模组左上角逆时针排序，引脚序号从 1 开始）对应的芯片引脚编号(1~254，这个根据芯片手册上的引脚编号来就可以)如果模组没有对应芯片引脚则设置为 NC</div>

<div> </div>

<div>映射三个LED的引脚，那么就用串口助手发送</div>

<div>AT+SYSIOMAP=22,PinMap:NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,NC,20,21,22</div>

<div> </div>

<div>串口助手回复：</div>

<div>flash save ok</div>

<div>AI_HalWriteFlash success</div>

<div> </div>

<div>则证明已经对PA12/PA13/PA14完成了映射</div>

<div>发送AT+SYSIOMAP?则会回复已配置的IO情况</div>

<div> </div>

<div><strong>②、设置 GPIO 输出电平</strong></div>

<div>命令：AT+SYSGPIOWRITE=<pin>,<level></div>

<div>参数：</div>

<div><pin>：模组 IO 引脚号。从模组左上角逆时针排序，引脚序号从 1 开始</div>

<div><level>：引脚电平。0：低电平，1：高电平</div>

<div> </div>

<div>点亮LED</div>

<div>AT+SYSGPIOWRITE=20,1</div>

<div>AT+SYSGPIOWRITE=21,1</div>

<div>AT+SYSGPIOWRITE=22,1</div>

<div>关闭LED</div>

<div>AT+SYSGPIOWRITE=20,0</div>

<div>AT+SYSGPIOWRITE=21,0</div>

<div>AT+SYSGPIOWRITE=22,0</div>

<div> </div>

<div></div>

<div></div>

<div>点灯成功~</div>

<div> </div>

<div> </div>
