HI LPRF,

Would you say me: How I can debuggin with IAR 7.51A + Zstack 1.4.3-1.2.1 to task level?

I marked ORTI RTOS in project options, but I have not found none* .ort file on Zstack, so I can not debuggin step by step into my tasks. I only can debugging step by step in zmain file.

Thanks an best regards,

Leonardo

Hi,

I have a little problem while using the CC2500. I am making a RF to RS232 Convertor. Baudrate is 4800Bps for RS232 and 250K for RF datarate. Using FIFO modes. Variable PAcket length. When I recieve a byte on the UART I send it via RF using TX buffer and the STX Command. Working well between 2 devices on 2 PC's independently. But when I transmit from both PC's one of the modules gives me the TX_UNDERFLOW State. Why is this happening and what does TX_UNDERFLOW signify. How can the buffer underflow when I am not issuing the STX command before writing to TX FIFO.

Please advise.

 

Thanks

Do you have any feedback on my most recent post: trouble initiating transmission with the CC2420 in buffered TX mode ?  Would appreciate it if you did.  Thx.
