Good RS232-based Protocols for Embedded to Computer Communication, Pictures of different adapters, trying to understand how they work (PLC to PC communication), How to calculate line capacitance for I2C (100kHz) communication, I2C communication between MPU6050 and MSP430FR2433. An appropriate converter between the two must be used. This Verilog FPGA design turns a cheap Altera Cyclone-II EP2C5T144 "minimum system board" into a nice I2C bus monitor. RS232C is a byte transport protocol. The language of this course is English. Alibaba.com offers 1,600 i2c rs232 products. An example is the Microchip 24LC41. Want to improve this question? Printing message when class variable is called, What do this numbers on my guitar music sheet mean. They are completely different protocols used for completely different things. To wrap serial in I2C, realize that it's possible to model a bidirectional serial link using the I2C multi-master capability. Preferred is hardware based solution so that no MCU programming is required & low power since system is battery powered. Serial to I2C Conversion makes it easy to talk to I2C devices using NCD standardized commands. Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts.
