Icom CI-V stepper allows tuning with stepper motor Nema 17 some devices dependancy to Icom frequency
Quick start guide
24V DC power Supply
TX inhibit output
Configure over USB CLI
Q1 - bad footprint pinout
Switch for calibrate start point motor stepper (zero step, zero °). After start up stepper spins reverse ↺ and wait for endstop signal who stops him and resets counters.
Connect two phase NEMA 17 stepper motor. Another type not supported. One of the phases is known by the ohmmeter. Another phase is isolated.
Activate by grounded +5V pull-up.
Connected to Icom or MicroHam CI-V outputs.
TX Inhibit output
Open collector without pull-up.
24V with 1A power rating. Lowest voltage accepted, but stepper lower torque.
USB Command Line Interface (CLI)
How to connect
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
How to start
after first boot login to serial console with default login pi and password raspberry
run command and enable SSH
run command and write down the shown IP address
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
screen /dev/ttyUSB0 115200
now after pres ?
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
For upload firmware you have two possibilities
Ordered List ItemDownload source
and compile in IDE
Download compiled binary
from release page
and upload with some tool
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
Write frequency and uSteps i to arrayunsigned_long_storagefreqtostep_112_2_7000000_0_7010000_500_7020000_1000_7030000_1500_7040000_2000
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
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 endstoplong_currentruntimeout_2_0_1000
