There are four lines I2C in MPC 5748G. Now,I have a MPC5748G and two MCP4725. I use the I2C_2(PE9_SCL, PE8_SDA) for one MPC4725 that one's address ox62. And use the I2C_3(PE10_SCL, PE11_SDA) for one MPC4725 that other's address ox63. Then I want to get two outV. I meet tow question.
- It is not working that I used the I2C clock. I can't get varying voltage on pin PE9_SCl and PE10_SCL.
- If I want to make MPC5748G became the mater, the address of MPC5748G how to get.
This is my procedur belowing.
