I'm trying to get the HopeRF RFM23B to work. What is the SPI-mode to be used?

I tested my theory and it is not valid.

I changed hw and sw SPI, slowed down the clock and put in small delays but it does not help.

So, I stop at this point. Maybe I will pick it up again in a ...

I work with cc2420 IEEE transceivers. They all have hw SPI but 1 has software SPI.

My conclusion this far is that the transmitter, hw SPI, and the receiver, sw SPI, do not cooperate due to the spee ...

Dear PCM programmer,

Again there are interesting and promising suggestions in your reply.

Especially your suggestion to find a small test routine is useful. And your suggestion to look for paral ...

Hello,

I need a software SPI for my cc240 radio. It runs fine with hw SPI, but the sw version on an 18F4525 does not work.

I use this code:

#USE SPI (MASTER,MSB_FIRST,DI=pin_A5,DO=pin_E1, ...

So, the code snippet I posted is their definition for the CCS spi_write()

OK, thanks

I am in the process of translating software for the CC2420 radio from C18 C to CCS C.

My question for this moment is: what do the back slashes mean. See code fragment below.

#define _SPI_WRITE ...

Thanks a lot, PCM programmer,

I believe this will help me to get the CC2420/EasyBee started !!!

I let let you know if it works.

Best regards,

Thank you, PCM programmer

The CC2420 has built in support for buffered transmit and receive and it should be not too difficult to implement that.

Actually I'm trying to program the Flexipanel Ea ...

Hi,

Is there anyone familiar programming the CC2420 radio in C ??

What I need is a buffered Tx and a buffered Rx.

It must be easy but I'm stuck.

Any help is highly appreciated.

Hello,

Did anyone use an IEEE 802.15.4 stack for CC2420 radio in CCS-C ?

I plan to use this in a kind of domotica application.

Thanks in advance,

I got the "cdc_NTXP.inf" file fom CCS, the USB-communication from PIC18F4550 to PC using USB seems to work now.

Thanks,

Klaus

Thank you for the information.

I already sent an email to CCS and I hope they will send me the file.

In the USB development kit there is mainly hardware and software I already bought from CCS.

No, it is not there. But thanks anyway.

Hello,

I'm in the pocess of building a first USB to PC (XPproSP2) connection using a PIC18F4550. I use ex_usb_serial.c and the libaries provided by CCS.

So far I get the following results:
