Diagnostic Aids
Two methods have been provided to aid in debugging.
loopback
This method checks for WiFi connectivity 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.py
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
The Telemetrix4RpiPicoW server 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
NOTE: You may also add Serial.println statements to the server sketch and use a
serial monitor to retrieve debug information.
