I will be looking into this. Got to estimate which approach would take less time.
Thank you.

Hello,

I have been using Accelerometer 2.0 bricklet and now I want to build a small remote node for more testing and instead of designing my own KX122 breakout board I would like to reuse Accel 2.0 bricklet. So, as my master I would be using ESP32 board and via short cable connect to the bricklet which would be mounted on the equipment.

Could someone guide my on what should I be including in my ESP32 firmware in order to talk to accelerometer 2.0 bricklet?

Thank you

General Discussion / Quadrature encoder Bricklet
« on: September 26, 2018, 16:35:51 »
Hello,

I would like to ask if there is a plan to make a quadrature encoder bricklet?

Since, we have a many bricklets that could be used for motion control or any industrial automations. But I keep missing quadrature encoder bricklet that could host encoders like AMT102.

I currently tried using IO bricklets and tie it to interrupts but for higher precision it's not enough.

Thanks

Cables and brick connectors were fine. Turns out it was USB hub, connecting directly to my laptop it works just fine.

Thanks!

General Discussion / RedBrick keeps resetting BrickViewer
« on: August 12, 2018, 03:19:14 »
Hi,

I have downloaded the latest RED brick image and Brick Viewer.
Got RED image on a 8GB SD card.


RED Brick keeps resetting on a viewer, I can't connect to it properly and upload any programs, because it keeps resetting before I am able to finish the upload.

And if I try to run a python example just to read linear pot values most of the times I get error
Code: [Select]
python3 Red_brick_pot_test_1.py
Traceback (most recent call last):
  File "/home/soso/Projects/MotionControl/env/lib/python3.5/site-packages/tinkerforge/ip_connection.py", line 1164, in send_request
    response = device.response_queue.get(True, self.timeout)
  File "/usr/lib/python3.5/queue.py", line 172, in get
    raise Empty
queue.Empty

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "Red_brick_pot_test_1.py", line 28, in <module>
    lp.set_position_callback_period(50)
  File "/home/soso/Projects/MotionControl/env/lib/python3.5/site-packages/tinkerforge/bricklet_linear_poti.py", line 127, in set_position_callback_period
    self.ipcon.send_request(self, BrickletLinearPoti.FUNCTION_SET_POSITION_CALLBACK_PERIOD, (period,), 'I', '')
  File "/home/soso/Projects/MotionControl/env/lib/python3.5/site-packages/tinkerforge/ip_connection.py", line 1173, in send_request
    raise Error(Error.TIMEOUT, msg)
tinkerforge.ip_connection.Error: Did not receive response for function 3 in time (-1)

And sometimes it just works. When I connect via USB to Master Brick, I never have any issues by accessing bricklets etc.

I am running ubuntu 16.04.

Could anyone help me identify and fix the problem?
