Icom CI-V stepper allows tuning with stepper motor Nema 17 some devices dependancy to Icom frequency

Quick start guide

Connect hardware (Stepper, Endstop switch, Power Supply, TX inhibit output, CAT)
Configure over USB CLI

Hardware

Connect

Endstop

Stepper

BCD input

Activate by grounded +5V pull-up.

CAT

TX Inhibit output

Power supply

USB Command Line Interface (CLI)

How to connect

Connect USB micro cable between CLI stepper and your PC
install PuTTY terminal
after run it set

com port dependency to your system
baudrate to 115200
Connection type to Serial
In Terminal category turn off options Implicit CR and Implicit LF by picture
press Open

CLI commands

After open PuTTY press character ? who show actual setting and available command

Secure remote manage

Configuration available via serial CLI (command line interface). This interface can be safely accessed to the Internet and encrypted connections to manage all features

What you need

any version Raspberry PI
microSD card with Raspbian Lite
micro USB cable
5V power adapter with micro usb cable
ethernet connection
for first start HDMI monitor and USB keyboard

How to start

after first boot login to serial console with default login pi and password raspberry
run command and enable SSH
```
sudo raspi-config
```
run command and write down the shown IP address
```
ip a
```
you can disconnect HDMI monitor and USB keyboard
connect to Raspberry PI from any other PC

update system with run command

sudo apt-get update && sudo apt-get upgrade

install screen fith command
```
sudo apt-get install screen
```
run screen
```
screen /dev/ttyUSB0 115200
```
now after pres any key show status information and you can configure via CLI
close screen with CTRL+A K and confirm y
disconnect from Raspberry PI use command
```
exit
```

Firmware

For upload firmware you have two possibilities

Download source from GitHub and compile in Arduino IDE

Install EEPROM library

Download compiled binary from release page and upload with some tool

for example avrdude or Xloader for windows

Firmware source

contains some settings which does not available from CLI

You can enter frequency and uStep directly in to firmware without CLI wizard. How to

Disable preset coment line
```
//#define RestoreMemoryFromEeprom
```

Write frequency and uSteps i to array

unsigned long StorageFreqToStep[112][2] = {
  {7000000, 0},
  {7010000, 500},
  {7020000, 1000},
  {7030000, 1500},
  {7040000, 2000},
  ..

Upload firmware
Select BCD input to bank-0 (must be, because only bank-0 saved also frequency, higest bank saved uStep only)
Save frequency/uStep table from RAM to EEPROM with command s in CLI
Replay edit table, upload and save for any higher bank
After fill EEPROM to your liking, enable command in source file
```
#define RestoreMemoryFromEeprom
```
After upload frequency/uStep table will be set by preset selected bank. For more info use command l or e in CLI.

Time (second number in ms) after which reduce stepper current and save last position to eeprom, if disable endstop
```
long CurrentRunTimeout[2] = {0,1000};
```
Enable serial debug if uncoment this line
```
#define SERIAL_debug
```
CLI baudrate, default is 115200
```
const int BAUDRATE0 = 115200;
```
