RF PGM upload
Application program can be uploaded into IQRF transceivers even wirelessly. This IQRF highlight is called ICWPTM (In-Circuit Wireless Programming). It is convenient for TRs which can not be plugged in a programmer (soldered, inaccessible etc.). RF PGM means a great advantage especially for network development. All nodes can be programmed at once in a few seconds. For development of huge networks it is a must.
Configuration
- Programmer: CK-USB-04 with TR-52BA, RFPGMCK plug-in inside, connected to PC with IQRF IDE Upload and C04-TX.hex loaded
- Programmed device: transceiver inside RC-04 (TR-52BA compatible)
Upload procedure
RF PGM upload is completely described in the
AN009 Application note. Details can also be found at
RC-04 User's guide.
Basic hints:
- Press pushbuttons 3 and 4 for more than 5 s to enter RF PGM mode
- Press pushbutton 2 for more than 0.7 s to leave RF PGM mode
- RC-04 indicates RF PGM mode by short red LED flashes in 2 s period
Operation
