ln2block

ln2block is the combination of hardware and software to send block messages in a Fremo meeting between two block enabled stations. There are more implementations for this, which can be found at fremo-block The ln2block variant aims to directly connect Loconet switchpanels to block. First implementation is done with https://smf-modelle.de/ Dr-S2 panels in the Loconet variant. But other implementations such as arduino based or felderblock are possible.

hardware

The hardware is a adaption of the boards shown here with the following adaptations:

• Schlüesselinterface integrated
• Arduino Nano based to ease programming and debugging
• OLED status display

v5 is a variant which has connections on both ends of the pcb.

v6 is adapted to fit the Strapubox SP2000 (again).

Getting parts:

Reichelt Shopping Cart for V5 parts: (https://www.reichelt.de/my/1871884). For logging purposes a SSD1306 OLED Display is used. Any I2C variant should work.

Manuals:

See the wiki

Software

Software is fully functional for:

• Tf71
• Relaisblock
• Felderblock

Programming the Arduino

To program the Arduino please use the Arduino IDE.

Prerequisites:

• Wire Library (included within IDE): needed for the U8g2 Library
• U8g2 Library: to write text and/or graphic on the OLED display
• LocoNet Library: to send/receive Loconet messages

Configuration

The ln2block software can be configured through LNCV programming. The values in scope are described at fremo-block. A spreadsheet to calculate the appropriate values for each LNCV is found at https://github.com/nh-finescale/ln2block/tree/main/documentation

This sheet also contains a HEX explanation to translate HEX values shown on the OLED display back into which LNCV are on and off.
