Exception in Tkinter Callback During myCobot 280 Pi Calibration

[jhordanhiro]

Description

I am encountering an issue with my myCobot 280 Pi during the calibration process. The error occurs when running the rasp_mycobot_test_gui.py script. The script fails with a Tkinter callback exception. This issue is preventing me from completing the calibration process.

Steps to Reproduce

1. Ran the rasp_mycobot_test_gui.py script on a Raspberry Pi connected to myCobot 280 Pi.
2. Selected the appropriate serial port (/dev/ttyAMA0) and baud rate (115200 or 1000000). // I tried to use both
3. Attempted to calibrate the robot arm by clicking the "Start Calibration" button.

Expected Behavior

The calibration process should start, and the robot arm should respond accordingly without any errors.

Actual Behavior

An exception is thrown in the Tkinter callback when the calibration function is invoked. The detailed error message is as follows:

Exception in Tkinter callback

Environment

• myCobot 280 Pi
• Raspberry Pi
• Atom v6.5

The last parameter of the send_angle interface ranges from 1 to 100. Please modify line 216 of the rasp_mycobot_test_gui.py file and change self.mycobot.send_angle(self.calibration_num, 0, 0) to self.mycobot.send_angle(self.calibration_num , 0, 20)
