SCI communication

Other Parts Discussed in Thread: RM48L952, HALCOGEN

Hi...,

i had interfaced sensor modules with RM48L952 safety MCU and viewed (Hexa decimal value of SCI)the output through terminal window, everything is fine i converted the hexa value output  manually to input analog voltage. i wand to communicate the SCI output to external Display processor to display the data. but i see and SCI port in RM48L952 and how can i do it. how to configure the SCI in halcogen to communicate the output value to external processor.

Thanks and regards

K.Manjunathan

    Hello Manjunathan,

    Are you using a terminal window application such as TeraTerm or Putty? If you alread have the serial communications coded and working with a PC this should be a task of connecting the right signals from the RM48 to your external controller (Rm48 SCI-Rx to external processor sci-tx, RM48-Tx to external processor Rx) and matching the settings between the two controller. i.e., baudrate, stopbits, parity, etc. settings.

    Is the external controller already configured or do you have to write the code for it as well? If it is already programmed, you would need to look up the sci requirements for the external processor/display to match settings as mentioned earlier but you should also be aware if the external processor/system requires specific packet requirements such as command, data length code, data, CRCs etc.

    Yes i am using Terminal window. i can able to view the output in terminal window. but i don't find any SCI - Rx and SCI - Tx pins in the RM48L952 MCU. attached images sir. i got some clarifications form your answer. please clarify few more doubts
