Hi,

I try the same configuration (Pi with UNO) using USB. What do You mean

with rename the dev port?

Thanks for Your help.

Hi, if you want to use the Horrus FW, you will find the assignment in the software at https://github.com/bqlabs/horus-fw/blob/develop/cpu_map.h.

Kind regards

hi, in my test phase I used a motor driver with success,

but the ZUM HAT has additional FET drivers for the LASER

and a direct connection to the UNO. That's the benefit.

best regards

The USB connector of the UNO is made of metal and must be insulated with tape,

otherwise there will be a short circuit in the power supply of the ZUM. (see picture)

Kind regards

I downloaded the Arduino SW from Mario on GITHUB and modified it (pin-addresses on Cyclop).
Motherboard = CYCLOP, baud rate = 57600.

modification arduino software

version.h
#define BUILD_VERSION "v.20210318"

configuration.h

#ifndef MOTHERBOARD
#define MOTHERBOARD BOARD_CYCLOP
#endif

#ifndef BAUDRATE
#define BAUDRATE 57600
#endif

check pin assignment

pins_CYCLOP.h
#define RIGHT_LASER_PIN 2
#define LEFT_LASER_PIN 3
#define RIGHT_LASER_LED_PIN 4
#define LEFT_LASER_LED_PIN 5
#define MICROSTEP A5

/*

*/
#define ENABLE_PIN_0 9
#define STEP_PIN_0 12
#define DIR_PIN_0 13

/**

*/
#define LIGHT_PIN A0

To see the work of the laser outside I mounted 2 additional LED. UNO pins 4 + 5

LaserDriver.ccp

void initialize_laser_driver(){
pinMode(RIGHT_LASER_PIN, OUTPUT);
pinMode(LEFT_LASER_PIN, OUTPUT);
pinMode(LIGHT_PIN, OUTPUT);
pinMode(RIGHT_LASER_LED_PIN, OUTPUT);
pinMode(LEFT_LASER_LED_PIN, OUTPUT);
digitalWrite(LIGHT_PIN, LOW); //turn light off
digitalWrite(RIGHT_LASER_PIN, LOW); //turn right laser off
digitalWrite(LEFT_LASER_PIN, LOW); //turn left laser off
digitalWrite(RIGHT_LASER_LED_PIN, LOW); //turn right laser LED off
digitalWrite(LEFT_LASER_LED_PIN, LOW); //turn left laser LED off
}

void left_laser_on(){
digitalWrite(LEFT_LASER_PIN, HIGH);
digitalWrite(LEFT_LASER_LED_PIN, HIGH);
laser_is_active = true;
}

void left_laser_off(){
digitalWrite(LEFT_LASER_PIN, LOW);
digitalWrite(LEFT_LASER_LED_PIN, LOW);
laser_is_active = false;
}

void right_laser_on(){
digitalWrite(RIGHT_LASER_PIN, HIGH);
digitalWrite(RIGHT_LASER_LED_PIN, HIGH);
laser_is_active = true;
}

void right_laser_off(){
digitalWrite(RIGHT_LASER_PIN, LOW);
digitalWrite(RIGHT_LASER_LED_PIN, LOW);
laser_is_active = false;
}

compile and upload

I use FabScanPi-Server 0.10.0

important and necessary changes in fabscan.setup on Raspberry pi

sudo nano /etc/fabscanpi/default.config.json

"connector": {
"type": "serial",
"firmware": "ciclop",
"baudrate": 57600,
"autoflash": "False",
"flash_baudrate": 115200,
"port": "/dev/ttyACM0"

autoflash must be set to False, otherwise arduino software will be overwritten.

USB connection UNO <---> Raspberry Pi USB1

I hope i could help, it works perfectly for me

I cant find any Fab Scan Hat (pi or uno), so I would like to use an Arduino UNO connected to the Pi.

If using an UNO rather than the HAT, do I need to change the UNO bootloader, or just upload the firmware ? 

I've downloaded the firmware on to the Uno from this github repo

mariolukas/FabScanPi-Firmware: Firmware of FabScanPi 3D Laser Scanner (github.com)

I can send commands to the Uno via UART with the serial monitor from the Arduino IDE.

I've also got the Pi side working, after connecting the Uno to the Pi via USB, the server starts up but I am getting the bootloader message in the FabScan Server log file

INFO - fabscan.server.FSScanServer: FabScanPi-Server 0.9.4
DEBUG - fabscan.scanner.interfaces: Scanner Type is: laserscanner
DEBUG - fabscan.scanner.laserscanner.driver.FSSerial: Port in Config found
DEBUG - fabscan.scanner.laserscanner.driver.FSSerial: Latest available firmware version is: v.20200624
INFO - fabscan.lib.util.FSUtil: b'avrdude-original: Using autoreset DTR on GPIO Pin 7'
ERROR - fabscan.scanner.laserscanner.driver.FSSerial: Communication error on port /dev/ttyAMA0 try other flashing baudrate than 115200. Maybe corrupted bootloader.

From the browser I get the error (shortened message here for brevity)

The FabScanPi server is currently not running

So any ideas on why the FabScan server has comms error to the Arduino firmware ? BTW I do not have any hardware/peripherals etc connected to the Arduino UNO yet - I presume there is no feedback from the UNO to the FabScan via serial in terms of peripheral state ?

Thanks
