Control system for converting PC serial port into I2C and multi-channel IO

The utility model provides a control system for converting a PC serial port into I2C and multi-channel IO, comprising an MCU module, upper computer software, a relay control module and a multi-channelIO signal acquisition module, the system depends on an MCU and a virtual instrument, and in order to adapt to the multi-purpose and integrated requirements in the automatic test field, open type andmodular specifications are adopted. The MCU and the upper computer are independent, so that the device is extremely high in compatibility, a user selects a module to select a model according to actualconditions, and the compatibility and stability of the module to be controlled are greatly improved. The MCU peripheral module is developed by adopting an embedded system, takes an application as a center, takes a computer technology as a basis, and meets the requirements on measurement and control onsite and universalization of functions, reliability, cost, size, power consumption and the like. 本实用新型提出了一种PC串口转I2C及多通道IO控制系
