此模块是我在以前公司做热风枪项目时设计的一个模块，用于实时显示当前温度，其精度可以达到1摄氏度，三位半液晶显示，界面美观，稍作改动也可用段码LED作为显示。 程序功能：10位A/D的温度采集（热电偶）；TN段码液晶驱动；温度补偿； 文件包括：所有C源程序；完整的项目文件包（基于MCU：HT46R23） PCB HT46R23 DATASHEET 三位半液晶片DATASHEET-This module is in my hot air gun to do before the company projects a module designed for real-time displays the current temperature, its accuracy can reach 1 degree Celsius, three semi-liquid crystal display, interface aesthetics, make a minor amendment to paragraph can also be used as a code LED display . Program features: 10-bit A/D Acquisition temperature (thermocouple) TN LCD driver code segment temperature compensation documents include: All C source code complete package of project documents (based on the MCU: HT46R23) PCB HT46R23 DATASHEET 3 semi-liquid crystal film DATASHEET

1. 本程序使用一个定时器和任意 2 个 I/O 口模拟一个串行口。 2. 1位起始位，8位数据位，1位停止位。发数据位时先发低位。 3. 支持半双工通讯。收、发波特率相同。 4. 应把定时器中断优先级设置为最高级。 5. 本程序每接收一个字节后就把它放到一个队列缓冲区中(也可使用环行缓冲区), 待缓冲区满后，将缓冲区中的内容原样发回。这是为了测试多字节连续收发的 能力和简化程序。实际应用中应防止缓冲区溢出。 6. 由接收转换到发送时要先调用 soft_send_enable ()； 由发送转换到接收时要先调用 soft_receive_enable ()。 7. 发送最后一个字节后如果要立刻转为接收，必须等待最后一个字节后发送完毕 while ( rs_f_TI == 0) // 等待最后一个字节发送完毕-err
