Serial Console
|
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
|
|
By default a serial console appears on pins 1 (TX GPIO0) and pin 2
|
|
|
|
|
|
(RX GPIO1). This console runs a 115200-8N1.
|
|
|
|
|
|
|
|
|
|
|
|
The board can be configured to use the USB connection as the serial console.
|
|
|
|

|
|

|
|
A BOOTSEL button, which if held down when power is first
|
2022-08-17 19:41:50 +02:00
|
|
|
|
applied to the board, will cause the RP2040 to boot into programming
|
|
|
|
|
|
mode and appear as a storage device to a computer connected via USB .
|
|
|
|
|
|
Saving a .UF2 file to this device will replace the Flash ROM contents
|

============
|

|
|
|

|
|
|
|
|
|
The Raspberry Pi Pico can be powered via the USB connector,
|
|
|
|
|
|
or by supplying +5V to pin 39. The board had a diode that prevents
|
|
|
|
|
|
power from pin 39 from flowing back to the USB socket, although
|
|
|
|
|
|
the socket can be power via pin 30.
|
|
|
|
|
|
|
|
|
|
|
|
The Raspberry Pi Pico chip run on 3.3 volts. This is supplied
|
|
|
|
|
|
by an onboard voltage regulator. This regulator can be disabled
|
|
|
|
|
|
by pulling pin 37 to ground.
|
|
|
|
|
|
|
|
|
|
|
|
The regulator can run in two modes. By default the regulator runs
|
2022-08-17 19:41:50 +02:00
|
|
|
|
in PFM mode which provides the best efficiency, but may be
|
2022-07-01 22:23:35 +02:00
|
|
|
|
switched to PWM mode for improved ripple by outputting a one
|
2022-08-17 19:41:50 +02:00
|
|
|
|
on GPIO23.
