-Microchip MRF24J40
--------------------------------------------------------------------------------
-
-This directory contains a capture of the communication between a custom sensor
-mote board [1] and a Microchip MRF24J40MA IEEE 802.15.4 transceiver module.
-
-It is not nearly a complete sample of what types of traffic are possible,
-it does not have any examples of cyclic mode, it doesn't even contain RX
-packets, other than an ACK.
-
-[1] The board used is available here:
-https://github.com/karlp/karlnet/tree/master/nodes/boxcar

-Logic analyzer setup
---------------------
-
-The logic analyzer used was a generic Saleae Logic clone (at 16MHz).
-
-The same configuration was used for all captures.
-
- Probe Pin Description
- -------------------------
- 0 nRESET
- 1 INT Signals the host MCU
- 2 SDI Slave data IN
- 3 SCK SPI clock
- 4 SDO Slave data OUT
- 5 nCS SPI chip select
- 6 VDD
-
-
-mrf24j40-reset-wakeup.sr
-------------------------
-
-Capture of power-on behaviour resetting the radio and rewriting its config
-as per the datasheet recommendations.
-
-The sigrok command line used was:
-
- sigrok-cli -d fx2lafw --config samplerate=16M:captureratio=2 \
- --time 10ms -o mrf24j40-reset-wakeup.sr -t nCS=f \
- --channels 0=nRESET,1=INT,2=SDI,3=SCK,4=SDO,5=nCS,6=VDD
-
-
-mrf24j40-wake-tx-ack.sr
------------------------
-
-Captures the host MCU waking the radio, sending a packet, and checking the
-interrupt flags for an ACK. The sequence is not necessarily optimal, but
-functional.
-
-The sigrok command line used was:
-
- sigrok-cli -d fx2lafw --config samplerate=16M:captureratio=70 \
- --time 20ms -o mrf24j40-wake-tx-ack.sr -t INT=r \
- --channels 0=nRESET,1=INT,2=SDI,3=SCK,4=SDO,5=nCS,6=VDD
