Dear Sir/Madam,
I am facing issue with MAX3232CPWR, when running at baud rate 115200, i can see garbage start showing on the UART terminal output. But when running lower speed like 57600, 9600, not issue found. some of the board is working correctly.
Please refer to the attached picture here. the waveform captured is when UART is power up and no sending any data at RX/TX line from PC via USB2UART converter. Can you advice if the pulse output look normal? and should I change the capacitor value, will it help?
best regards,
kpk
