Hello everyone, I have a problem. I'm practicing using the esci serial port function module of mpc5634m. The problem is that the data sent by the upper computer is different from the data received by the MCU, and the data sent by the MCU is also inconsistent with the data received by my upper computer. The baud rate settings on both sides are the same, 9600. I don't know why? Does anyone know?
For example, I send hexadecimal 0x03 on the upper computer, and I observe that the value in the register of the MCU is 0x7e, then the MCU sends out 0x7e, but the upper computer receives 0x20. Then I test that the upper computer sends out 0x7e, and the value in the register of the MCU is 0x20, then the MCU sends out 0x20, and the upper computer receives 0x03, completing a cycle.
