The SPROG II / 3 and SPROG nano are relative easy to use and economically priced DCC Generator/Programmer with some extras.
¹) The mode word is currently not changed if the speed step of a loco is not set to 128.
Rocrail sends every 25ms a byte string like "
O 73 3F CC 80" as a command to SPROG II which on its turn generates the real DCC packet on the track output.
This byte string is a hexadecimal representation of the DCC packet to be send. A complete refresh cycle will take about 4 seconds if all 128 slots are in use.
Only the IID and the serial port has to be set, the rest is fixed in the firmware of the SPROG line.
SPROG 3 and S_Nano have device name "/dev/ttyACM0" under Linux.
The Pi-SPROG can only be used if Rocrail runs on the Raspberry Pi on which the Pi-SPROG is connected.
Pi-SPROG has the device name "/dev/ttyAMA0" under Linux/Raspbian.
Use the RCAN/CBUS library with serial 115200, and as device
The serial BPS must be set to 460800.
