Diagnostic Aids
Two methods have been provided to aid in debugging.
loopback
This method allows you to check that there is serial communication between the client and the server.
def loop_back(self, start_character, callback=None)
This is a debugging method to send a character to the pico device,
and have the device loop it back.
:param start_character: The character to loop back. It should be an integer.
:param callback: Looped back character will appear in the callback method
Example: loop_back
Sample Output
Sending: A Sending: B Sending: Z Looped back: A Looped back: B Looped back: Z
get_pico_pins
def get_pico_pins(self):
This method returns the pico_pins dictionary
:return: pico_pins
The keys in the dictionary returned from this method are the GPIO pin-numbers. The value is the pin type assigned to the pin:
Pin Mode MAP:
PIN TYPE | VALUE |
---|---|
DIGITAL_INPUT | 0 |
DIGITAL_OUTPUT | 1 |
PWM_OUTPUT | 2 |
DIGITAL_INPUT_PULLUP | 3 |
DIGITAL_INPUT_PULL_DOWN | 4 |
ANALOG_INPUT | 5 |
i2c | 9 |
NEO_PIXEL | 10 |
MODE_NOT_SET | 255 |
Example: get_pico_pins.py
Sample Output
{0: 255, 1: 255, 2: 255, 3: 255, 4: 9, 5: 9, 6: 0, 7: 255, 8: 255, 9: 3, 10: 255, 11: 255, 12: 255, 13: 255, 14: 10, 15: 255, 16: 255, 17: 255, 18: 255, 19:255, 20: 255, 21: 255, 22: 255, 25: 255, 26: 255, 27: 5, 28: 255}
Sending: A Sending: B Sending: Z Looped back: A Looped back: B Looped back: Z
send_debug_info reports
Telemetrix4RpiPico contains the send_debug_info function that allows you to send internal values back to the client and display them on the console.
void send_debug_info(byte id, int value)
The report is formatted as follows:
DEBUG ID: byte_id Value: int_value
