MSP430FG439: Flow control

Hee-Choel Hwang

Part Number: MSP430FG439

Hi..

We made custom board with MSP430FG439 and INI321 and connect to PC serial port.

I think that MSP430 send ADC data very quickly.

So, PC application lost some ADC Data.

Is it possible flow control between MSP430 and PC uart communication?

Thnks.

    Hi,

    For MSP430, we don't support flow control function for UART.

    But you means that loss data for PC? why? have you try to capture some wavefomr in TXD/RXT wires?

    MSP430 be able to capture analog signal via ADC, but I think you can send those data to PC, then start to next convert. This should not root cause for lost data.

    Thanks!

    Best Regards
