You talk a lot about poor cc2500EM performance, but you do not tell us the parameters you are programming it with. What modulation (you want FSK or GFSK)? What frequency deviaiton (bigger is better for range)? What IF receiver bandwidth do you have set? What data rate and packet size? Have you checked to see if the transmit and receiver boards

Hi I am about to start using the cc2500 chip and while reading the manual I read "ESD precaution should be taken". Should I take this warning seriously or I can just ignore it (because it is written on most of the electronic components). Did any one had troubles with ESD when working with the cc2500 or you were able to handle them just like a res
Hello, Microcontroller p89v51rd2 supports spi protocol. I have worked on spi communication i.e master to slave and slave to master data transfer. Please can anyone suggest me on how to start with the interface of these cc2500 modules to my controller. Can someone give me the detailed procedure, I have no knowledge about it. Thanks
i have found that, when i write an even no data(eg: 0x02) to a reg of cc2500,i got output always 0x0F when i read same reg. And when i write an odd no data(eg 0x05 (00000101) ) to a reg, i got output one bit rotated 0x82 (10000010). Thanks in advance.
a complete design can be found on this includes schematic and source code, it uses the cc2500 transceiver..
At first, RF is not easy... CC1100 is a Chipcon's product, but the company belongs to TI. refer to the site 1. Check the PCB layout : recommend exactly same as the reference design. gerber file is opend. review this first. PCB Antenna pattern is opened, too. 2. the passive elements, such as R/L/C, is importa
First you should choose a transceiver, I recommend using o chip from Chipcon - Texas Instruments, like CC1000 or the newer and better but only in QFN package, CC1101. You will find more info on the TI site. You may also want to look at the ti-store because there is a solution for you with a uC and cc2500. For the microcontroller you can use fo
what do you think about a small pcb with an Actel nano FPGA( ) on it and an TI MSP430-cc2500 (see also eZ430-RF2500 on ) combination... it will rule.. I was thinking of it but you can't place the actel nano FPGA yourself you have to do an pcb and place order to someone....

Hi, I am new to ADS layout simulation. I have simulated the folded dipole microstrip antenna suggested by TI(Texas Instruments) for transreceiver chip cc2500 to work for 2.4GHz frequency in ADS (whose datasheet is attached) but I am not getting the desired output. I have attached the method that I followed with the datasheets required.
here are the example libraries for CC1100 CC1101 CC1100E cc2500: RAF
As said in the datsheet, the module is based on TI cc2500. So just look for the respective datasheet, applications notes an d software tools.
I have recognized the plots, they are coming from CC1101 or cc2500. Please consider that these plots are the same plot, the secoond one just a zoom of the first one. They do not represent a simple filter transfer function, but an overall response of a complete receiver. These test are done injecting an interferer at a certain offset and increasing
I hav the ez430-rf2500-seh solar energy harvesting tool. I decided to make some modification based on the Demo code. I wanna choose P3.5 (UART) as a receive pin.
