Hi I want to simulate the I2C, and find this example
// Simulation of I2C Memory (Slave) MAP V:0,V:0xFFFF READ WRITE // Map User 64kB Memory region DEFINE int SADR // Slave Address signal void I2CMEMORY (void) { unsigned long adr; adr = V:0; while (1) { wwatch (I2C_OUT); // Wait for data from Microcontroller while (I2C_OUT == 0x0100) { // START detected wwatch (I2C_OUT); // Wait for data from Microcontroller if (I2C_OUT > 0xFF) continue; if ((I2C_OUT >> 1) != SADR) continue; // test if Slave is addressed I2C_IN = 0xFF00; // ACK to Microcontroller if (I2C_OUT & 1) { // Slave Read while (1) { I2C_IN = _RBYTE(adr); // Read Byte from Memory adr++; // Increment Address wwatch (I2C_OUT); // Wait for ACK from Microcontroller if (I2C_OUT != 0xFF00) break; } } else { // Slave Write wwatch (I2C_OUT); // Wait for data from Microcontroller if (I2C_OUT > 0xFF) continue; adr = (I2C_OUT << 8) | V:0; // Set Memory Address High Byte I2C_IN = 0xFF00; // ACK to Microcontroller wwatch (I2C_OUT); // Wait for data from Microcontroller if (I2C_OUT > 0xFF) continue; adr = I2C_OUT | adr; // Set Memory Address Low Byte I2C_IN = 0xFF00; // ACK to Microcontroller while (1) { wwatch (I2C_OUT); // Wait for data from Microcontroller if (I2C_OUT > 0xFF) break; _WBYTE (adr, I2C_OUT); // Store Byte in Memory adr++; // Increment Address I2C_IN = 0xFF00; // ACK to Microcontroller } } } } } SADR = 0x54 // Slave Address I2CMemory() // Starting signal function
