{TOC} [<-- WEB |https://remoteqth.com/civ-stepper.php] 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 ##24V DC power Supply ##TX inhibit output ##CI-V # '''Configure over USB CLI''' !Hardware * [Schematics rev0.2 .pdf|https://remoteqth.com/hw/civ-stepper-02.pdf] * [Interactive BOM|https://remoteqth.com/hw/civ-stepper-02-ibom.html] !Connect !! Endstop Switch for calibrate start point motor stepper (zero step, zero °). After start up stepper spins reverse &#8634; and wait for endstop signal who stops him and resets counters. [https://remoteqth.com/img/wiki-civ-stepper-05.png|noborder] !! Stepper Connect two phase '''NEMA 17''' stepper motor. Another type not supported. One of the phases is known by the ohmmeter. Another phase is isolated. * If stepper rotate reverse, you can change polarity one phase or activare reverse from CLI. [https://remoteqth.com/img/wiki-civ-stepper-04.png|noborder] !! BCD input Activate by grounded +5V pull-up. [https://remoteqth.com/img/wiki-civ-stepper-06.png|noborder] !! CAT Connected to Icom or MicroHam CI-V outputs. [https://remoteqth.com/img/wiki-civ-stepper-07.png|noborder] !! TX Inhibit output Open collector without pull-up. [https://remoteqth.com/img/wiki-civ-stepper-08.png|noborder] !! Power supply 24V with 1A power rating. Lowest voltage accepted, but stepper lower torque. [https://remoteqth.com/img/wiki-civ-stepper-03.png|noborder] !! USB Command Line Interface (CLI) !!! How to connect * Connect USB micro cable between CLI stepper and your PC * install [PuTTY terminal|https://www.putty.org/] * 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 [https://remoteqth.com/img/wiki-civ-stepper-02.png] ** press '''Open''' !!!CLI commands After open PuTTY press character [?] who show actual setting and available command [https://remoteqth.com/img/wiki-civ-stepper-01.png] !!! 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 [https://remoteqth.com/img/wiki-civ-stepper-09.png|noborder] What you need * any version Raspberry PI * microSD card with [Raspbian Lite|https://www.raspberrypi.org/downloads/raspbian/] * 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|https://www.raspberrypi.org/documentation/remote-access/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 ** [windows|https://www.raspberrypi.org/documentation/remote-access/ssh/windows.md] ** [Linux|https://www.raspberrypi.org/documentation/remote-access/ssh/unix.md] ** [iOS|https://www.raspberrypi.org/documentation/remote-access/ssh/ios.md] * 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 ? key show status information and you can '''configure via CLI'''[https://remoteqth.com/img/wiki-civ-stepper-01b.png] * 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|https://github.com/ok1hra/CI-V_stepper] and compile in [Arduino IDE|https://www.arduino.cc/en/Main/Software] ## Install [EEPROM library|https://www.arduino.cc/en/Guide/Libraries] # Download '''compiled binary''' from [release page|https://github.com/ok1hra/CI-V_stepper/releases] and upload with some tool ## for example [avrdude|http://www.ladyada.net/learn/avr/avrdude.html] or [Xloader|http://xloader.russemotto.com/] 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;}} !MQTT variant * need install wiznet ethernet module * use another firmware [GitHub|https://github.com/ok1hra/MQTT-stepper] * for setup and control see source code header
