a problem about CC256x MT UART BRIDGE
I have made a uart bridge according to the document of CC256x MT UART BRIDGE and made some modifications myself. The uart bridge work well when baudrate <= 57600. But It works unstable when baudrate=115200. I think the reason is that crystal on EZ430 board is 32.768kHz and the SMCLK(18MHz) is from DCO by FLL loop. I am going to increase crystal to 8MHz. But I find that there is clock signal(32.768kHz slow clock) output to PAN1325. I want to know:
1. May I transfer data through uart bridge with 115200 baudrate by increase crystal frequency?
2. Have slow clock signal to PAN1325 to be 32.768kHz?
The 115200 UART baud rate is supported and should work. Please make sure the clock crystals used have the recommended specifications. The slow clock (RTC) must be 32.768kHz and meet the 100ppm stability requirement.
thanks Arild Kolsrud
My be the crystal I used not be good enough supporting 115200 baud rate, or my other device's baud rate is not accurate.
