这一类问题在各类论坛中被反复提及，虽然本质上更多涉及硬件调试而非Proteus仿真本身，但由于它常常让开发者困惑，这里一并指出。仿真环境中JHD-2X16-I2C内置模型的功能、延迟特性和I2C总线行为是基于软件的抽象和模拟，与真实的LCD硬件（如使用PCF8574适配板+标准1602 LCD）存在差异。因此，。例如，仿真中的0x7C地址在实物中几乎不可能对应任何真实的I2C模块。在使用PCF8574实物模块时，代码中的地址应改为0x27或0x3F。此外，仿真中允许忽略的时序细节在真实硬件中可能会成为致命的错误。 jhd2x16i2c proteus exclusive

Go to System -> Set Simulation Options and change the single-step delay, or lower the operating frequency of your microcontroller property settings (e.g., set Arduino clock from 16MHz to 8MHz temporarily). If you want to refine this setup, let me know: What microcontroller are you using for the simulation?

: The simulation works sporadically, missing characters, or crashing. Cause : As confirmed by Labcenter staff, the Proteus JHD1214 model (upon which the JHD2x16I2C is based) does not support the "busy flag" read operation. It is a write-only device. Solution : In your firmware, replace any loops waiting for the Busy Flag with fixed, robust delays. For example, after sending a command, wait for 2ms; after sending a character, wait for 50 microseconds. Never attempt to read from the LCD's data pins over I2C.
