Part Number: TMS320F28335
Other Parts Discussed in Thread: SYSCONFIG
Tool/software:
To get the best accuracy (less than 0.02%) @ 115200 baud rate, what the SYSCLK and LSCLK to be used, please elaborate. for the TMS 320 controller baud rate tolerance.
One of our customer using the receiver system designed to accept the baud rate accuracy <0.02% @ 115200 baud rate on TMS320F28335.
Hi Shivaraju,
We have a baud rate error calculator available for some of our newer devices (gen 3 and newer) which can be used to find a LSPCLK frequency with low error. I would suggest using this tool with a newer device that has the same SYSCLK frequency as F2833x (for example F28P55x) and finding the most optimal baud rate/LSPCLK frequency combination for your application. The LSPCLK divider can be changed in the clock tree of Sysconfig and the baud rate can be changed directly in the SCI Sysconfig module to calculate the resulting error (shown as:"Baud Rate Error Percent [%]").
