Other Parts Discussed in Thread: TEST2, CC2640R2F, CC2652R
Hello,
in a project where I am supposed to work, I am allowed to work with the RF products of TI. But I am still quite inexperienced and would be grateful if someone might recommend a good entry guide.
Specifically, I have a CC2500 with the settings listed below that I want to connect to. Unfortunately there seems to be hardly any development products left for the CC2500, so I am wondering which current chip I should use to connect with the CC2500 with the given settings or is there an overview of the compatibility between the different RF products from TI?
Thanks in advance for your help.
CC2500 RF-Settings:
// Product = CC2500
// Crystal accuracy = 40 ppm
// X-tal frequency = 26 MHz
// RF output power = 0 dBm
// RX filterbandwidth = 540.000000 kHz
// Deviation = 0.000000
// Return state: Return to RX state upon leaving either TX or RX
// Datarate = 250.000000 kbps
// Modulation = (7) MSK
// Manchester enable = (0) Manchester disabled
// RF Frequency = 2433.000000 MHz
// Channel spacing = 199.950000 kHz
// Channel number = 0
// Optimization = Sensitivity
// Sync mode = (3) 30/32 sync word bits detected
// Format of RX/TX data = (0) Normal mode, use FIFOs for RX and TX
// CRC operation = (1) CRC calculation in TX and CRC check in RX enabled
// Forward Error Correction = (0) FEC disabled
// Length configuration = (1) Variable length packets, packet length configured by the first received byte after sync word.
// Packetlength = 255
// Preamble count = (2) 4 bytes
// Append status = 1
// Address check = (0) No address check
// FIFO autoflush = 0 - NoteMe LH9527: autoflush=1 in TI_CCxxx0_PKTCTRL1 => Vermeidung der Weitergabe von Tels mit CRC-Fehlern an MSP (nur bei Tel-Längen < FIFO-Länge zulässig!)
// BEM1: Evtl. autoflush standardmäßig einschalten, jedoch nach Empfang Bind-Request (bis Funk-TimeOut) ausschalten -> dann auch lange Daten-Tels möglich.
// BEM2: Noch längere Daten-Tels (z.B. angepasst an FTP-Tel-Datenlänge 0x200) sind möglich, wenn nach RF-Header im RF-Data-Packet eine 2-Byte-Länge eingefügt wird.
// Siehe auch "NoteMe" in RFReceivePacket() weiter unten in dieser Datei.
// Device address = 0
// GDO0 signal selection = ( 6) Asserts when sync word has been sent / received, and de-asserts at the end of the packet
// GDO2 signal selection = (11) Serial Clock
