Sometimes I'll get the gibberish again, most times I just get a blank screen with boxes that I can manipulate using the contrast.Īt the moment I cannot get anything to pop up on the screen, other then lines 1 and 3 showing the completely filled character space (the boxes when I raise the contrast to full), while lines 2 and 4 do not respond. I basically plug everything into the bb and arduino and then power it up. Is there a specific way of working the LCD? I am going to return this one for a new one (different brand/manufacturer). I've tried moving it to another area on the bb, check, recheck and re-rechecked the connections and everything was fine. I can get the contrast to work fine but the information doesn't display (i.e. While it did work for a short while using the 4 wires, I still have yet to be able to continually receive a constant working display. I've testing the soldering and there doesn't seem to be an issue with and shorting of pins. I believe there is a problem with the actual LCD. Well it seems that the issue wasn't that simple. Just the 16 header pins connected directly to my bb and soldered onto the display board. I've tried searching but everyone has an I2C module (I think that is what it is called) connected on the back. Whenever I re-load the code I get a new set of gibberish across the 2 lines.Ĭan anyone point me in the right direction? I use a switch to disconnect the power/ground from the display. Lcd.print("1234567890abcdefghijklmnopqrstuvwxyz") Īll I get is gibberish though across 2 lines. set up the LCD's number of columns and rows: initialize the library with the numbers of the interface pins I change the lcd.begin from 16,2 to 20,4. I am using the built-in examples from the arduino IDE. I am very new to arduino and fairly new to programming. I tried with an ESP32 board that is shields compatible, same result, worked when connected directly but not when shield installed.That is the item I've purchased. I attaching them to the Arduino Mega 2560, same result, did not work. Please, do you have any idea what I was missing, or if the 2 shields required something else for the sensor, or should I RMA the 2 shields that were not accepting the sensor? Thank you in advance.Įdit: I did try the 2 shields with some other boards, one by one, not stacked. So at this point, only by using the Aliexpress Shield or Directly connecting SCL and SDA could the sensor be read. With this problem, I tried removing the shield from the Uno and connecting the I2C pins directly onto the board, which worked just as expected. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. However, with the Aliexpress shield I got, the sensor worked flawlessly, and angles and velocity were read as how they should be. Tech Specs Compatibility Suggested Libraries The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. Sometimes, when the shields are installed, the Serial mornitor in the Arduino IDE stops completely and indefinitely, requiring a restart of the application to be able to work again. I tried migrating the SDA and SCL to A4 and A5 on the lower left corner but there was no difference. It always shows a fixed number of 12.60 for angle, and 0.00 for speed. Now, with the 2 shields I got from the link above installed, the Uno does not seem to be able to properly get the data from I2C sensor. display the angle and the angular velocity to the terminal has to be called before getAngle nad getVelocity this function reads the sensor hardware and it is usually called in motor.loopFOC() ![]() iterative function updating the sensor internal variables MagneticSensorI2C sensor = MagneticSensorI2C(AS5600_I2C) Then I loaded up the example sketch in the utils for the AS5600, which would look like this: #include ![]() The AS5600 has a total of 7 pins, 5 of which I connected to the shield according to the guide on the document website, that is: VCC to 5V on shield, GND to GND on shield, DIR to GND on shield, SCL to SCL on shield, SDA to SDA on shield, GPO and OUT pins are left unconnected. The board I was using was the Arduino Uno, no stacked shield. Google 'Arduino Mega pinout' and go to images. As far as I found, both wiring schematics go to the SCL and SDA pins of the mega. I did some open_loop examples testing and the three were doing fine, until I hooked up the AS5600 encoder to the shield. Hello I got both a general I2C LCD for Arduino and a DS3231 clock module. Some weeks ago I ordered 3 Shields of the SimpleFOC project, 2 of which I ordered from one place ( Simplefoc Shield V2.0.4 V1.3.3 Development Board for BLDC Servo Drive of Mechanical Dog), and the other one I ordered from another place (Aliexpress). I am having trouble with two SimpleFOC Shields and the AS5600 sensor.
