-- I want to share information of size something around 400 bytes between the two 8051 uC. One uC will write into 24c02 and other uC will read it. Unable, the 24C02 store only up to 256 byte (2048 bits / 8). Furthermore both masters must be true multi master. Software I2C can only be single master. You need 8051 with hardware I2C, which are able to solve arbitration. Peter |
