Hello everyone,
I’d like to switch from Arduino IDE to PlatformIO because the program I’m writing is getting more and more complex and the advanced features of this platform would come in handy.
I started out with the basic LED blinking app and everything worked fine. Upload was successful, Serial showed the messages. My platformio.ini file was the exact same I copied down below except for the lib_deps part.
Then I created a new project, copied my code, added the required dependencies to the .ini file and my Serial stopped working.
Here’s my platformio.ini file:
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
monitor_speed = 115200
upload_port = /dev/cu.SLAB_USBtoUART
monitor_port = /dev/cu.SLAB_USBtoUART
lib_deps =
arduinogetstarted/ezButton @ ^1.0.4
adafruit/RTClib @ ^2.1.1
SPI
I’m on a MacBook and the SiLabs USB drivers are installed to make the Arduino IDE work.
pio device list --serial
outputs
/dev/cu.Bluetooth-Incoming-Port
-------------------------------
Hardware ID: n/a
Description: n/a
/dev/cu.usbserial-0001
----------------------
Hardware ID: USB VID:PID=10C4:EA60 SER=0001 LOCATION=1-1

/dev/cu.SLAB_USBtoUART
----------------------
Hardware ID: USB VID:PID=10C4:EA60 SER=0001 LOCATION=1-1
Description: CP2102 USB to UART Bridge Controller
If I don’t specify the upload port, then it finds the /dev/cu.usbserial-0001, which didn’t work on Arduino IDE.
Here is the output of the upload:

How can make the Serial work?
UPDATE: Seems like a dependency problem… I added this to my ini file for the LED blinking project, which didn’t have any dependencies:
lib_deps =
arduinogetstarted/ezButton @ ^1.0.4
adafruit/RTClib@^2.1.1
and I get this:
