### 测试
|
||
|
||
串口中断发送通过测试
|
||
|
||
spi_flash读写通过测试
|
||
|
||
对智能模块通信串口，阻塞发送数据通过测试。
|
||
|
||
|
||
|
||
|

|

|
||
|
||
### 问题
|
||
|
||
#### 串口中断
|
||
|
||
25/02/24
|
||
|
||
在freerots环境下，中断不生效
|
||
|
||
解决
|
||
|
||
> 25/02/25
|
||
>
|
||
> 需要启动freerots任务
|
||
>
|
||
> 同时中断部分
|
||
>
|
||
> ```c
|
||
> void UART5_IRQHandler(void) __attribute__((interrupt("WCH-Interrupt-fast")));
|
||
> ```
|
||

|
||
> 变为
|
||
>
|
||
> ```c
|
||
> void UART5_IRQHandler(void) __attribute__((interrupt()));
|
||
> ```
|
||
>
|
||
> 其他中断同上，由硬件压栈变为软件压栈

#### 串口发送的数据不正确
|
||
|
||
25/02/28
|
||
|
||
解决
|
||
|
||
将数据通过队列发送，需要将buff的位置移动到起始位置+结构体长度
|
||
|
||
```c
|
||
uint8_t *Buff = (uint8_t *)pvPortMalloc(200);
|
||
if (Buff == NULL) {
|
||
log_error("Memory allocation failed\n");
|
||
return;
|
||
}
|
||
|
||
queueUartSendInfo *sendBuff = (queueUartSendInfo *)Buff;
|
||
sendBuff->length = sizeof("hello world\n");
|
||
sendBuff->data = Buff + sizeof(queueUartSendInfo);
|
||
strlcpy((char *)sendBuff->data, "hello world\n", sizeof("hello world\n"));
|
||
// for (int i = 0; i < sizeof("hello world\n"); i++) {
|
||
// sendBuff->data[i] = data[i];
|
||
// }
|
||
// *sendBuff->data = *data;
|
||
// *sendBuff->data = 'H';
|
||
|
||
log_info("dataLen:%d\n", sendBuff->length);
|
||
log_info("data:%s\n", sendBuff->data);
|
||
xQueueSend(upward_uart_Queue, &Buff, 10);
|
||
vTaskDelay(1000);
|
||
```
|
||
|
||
|
||
|
||
#### 中断中不能分配和释放内存
|
||
|
||
解决
|
||
|
||
中断中添加信号量，通知任务来释放。
|
||
|
||
|
||
|
||
|
||
|
||
## 接收解析
|
||
|
||
#### su806传来的数据
|
||
|
||
见网关单片机通信协议
|
||
|
||
#### 传感器传来的数据
