+## DHT11 Output Data Format

+

+The DHT11 sensor outputs data in the following format:

+

+**Data Structure:** `8-bit humidity integer + 8-bit humidity decimal + 8-bit temperature integer + 8-bit temperature decimal + 8-bit checksum`

+

+### Data Breakdown:

+- **Byte 1:** Humidity integer part (8 bits)

+- **Byte 2:** Humidity decimal part (8 bits)

+- **Byte 3:** Temperature integer part (8 bits)

+- **Byte 4:** Temperature decimal part (8 bits)

+- **Byte 5:** Checksum (8 bits)

+

+

+

+

+由以上数据就可得到湿度和温度的值，计算方法：

+湿度 = byte4 . byte3 = 45.0(%RH)

+温度 = byte2 . byte1 = 28.0(℃)

+校验（byte5） =？ byte4 + byte3 + byte2 + byte1 = 73 (= 湿度 + 温度) （如果相等则校验正确）

+时序简介：主机（ESP32）向DHT11发送传输数据命令（拉低再拉高）->DHT11响应收到命令（拉低再拉高引脚）->DHT11向主机（ESP32）传输数据（拉低再拉高）

+

+

+命令发送和响应

+

+

+

+数据0：

+

+

+

+数据1：

+

+

+

+说明：上图中的特定值，其实是按要求时间段取的一个中间值，具体范围大家可以查询手册。

+

+时序总结：无论是主机向DHT11发送还是DHT11向主机发送，都是拉低再拉高引脚完成一个动作，包括命令、应答、发送1bit数据，不同的是拉低的时间和拉高的时间

+## Interrupt Control Issues Troubleshooting

+

+**Arduino examples wiki link:** https://docs.espressif.com/projects/arduino-esp32/en/latest/libraries.html

+

+### Common Issues and Solutions:

+

+1. **Interrupt functions need the `ARDUINO_ISR_ATTR` macro**

+2. **Use serial debugging**

+3. **Program crashes due to incorrect flash size settings**

+## OLED Memory Layout

+

+The following diagram shows the display memory layout: **64×128 bits**

+

+

+

+### Data Types

+

+Data written to the OLED screen is divided into two types:

+

+1. **Command Type:** Controls cursor position and other settings

+ - Format: `0x00 + command_value`

+ - Example: Setting cursor position

+

+2. **Data Type:** Writes values to the display buffer

+ - Format: `0x01 + data_value`

+ - Example: Writing pixel data

+

+### Display Principle

+

+The display works by:

+

+1. **Buffer Allocation:** Create a buffer matching the screen size

+ - **Buffer Size:** `64 × 128 ÷ 8 = 1024 bytes`

+

+2. **Buffer Modification:** Update the buffer content as needed

+

+3. **Display Refresh:** Send the entire buffer content to display memory

+ - **Refresh Method:** Update all columns in the display memory simultaneously
