CPU Frequency¶
See board_build.f_cpu option from “platformio.ini” (Project Configuration File)
[env:myenv]
; set frequency to 160MHz
board_build.f_cpu = 160000000L
FLASH Frequency¶
Please use board_build.f_flash
option from “platformio.ini” (Project Configuration File) to change
a value. Possible values:
40000000L
(default)80000000L
[env:myenv]
; set frequency to 80MHz
board_build.f_flash = 80000000L
FLASH Mode¶
Flash chip interface mode. This parameter is stored in the binary image header, along with the flash size and flash frequency. The ROM bootloader in the ESP chip uses the value of these parameters in order to know how to talk to the flash chip.
Please use board_build.flash_mode
option from “platformio.ini” (Project Configuration File) to change
a value. Possible values:
qio
qout
dio
dout
[env:myenv]
board_build.flash_mode = qio
External RAM (PSRAM)¶
You can enable external RAM using the next extra build_flags in “platformio.ini” (Project Configuration File) depending on a framework type.
Framework Arduino:
[env:myenv]
platform = espressif32
framework = arduino
board = ...
build_flags =
-DBOARD_HAS_PSRAM
-mfix-esp32-psram-cache-issue
Framework ESP-IDF:
[env:myenv]
platform = espressif32
framework = espidf
board = ...
build_flags =
-DCONFIG_SPIRAM_CACHE_WORKAROUND
More details are located in the official ESP-IDF documentation - Support for external RAM.
Debug Level¶
Please use one of the next build_flags to change debug level. A build_flags option could be used only the one time per build environment. If you need to specify more flags, please separate them with a new line or space.
Actual information is available in Arduino for ESP32 Board Manifest.
Please scroll to esp32.menu.DebugLevel
section.
[env:myenv]
platform = ...
board = ...
framework = arduino
;;;;; Possible options ;;;;;;
; None
build_flags = -DCORE_DEBUG_LEVEL=0
; Error
build_flags = -DCORE_DEBUG_LEVEL=1
; Warn
build_flags = -DCORE_DEBUG_LEVEL=2
; Info
build_flags = -DCORE_DEBUG_LEVEL=3
; Debug
build_flags = -DCORE_DEBUG_LEVEL=4
; Verbose
build_flags = -DCORE_DEBUG_LEVEL=5
Upload Speed¶
You can set custom upload speed using upload_speed option from “platformio.ini” (Project Configuration File)
[env:myenv]
upload_speed = 9600
Erase Flash¶
Please platformio run --target
the next command to erase the entire
flash chip (all data replaced with 0xFF bytes):
> platformio run --target erase
# or short version
> pio run -t erase
Enable C++ exceptions¶
Please add -D PIO_FRAMEWORK_ESP_IDF_ENABLE_EXCEPTIONS
to build_flags
of “platformio.ini” (Project Configuration File) to enable C++ exceptions for ESP-IDF.
See project example.
Partition Tables¶
You can create a custom partitions table (CSV) following ESP32 Partition Tables documentation. PlatformIO uses default partition tables depending on a framework type:
default.csv
for Arduino (show pre-configured partition tables)partitions_singleapp.csv
for ESP-IDF (show pre-configured partition tables)
To override default table please use board_build.partitions
option in
“platformio.ini” (Project Configuration File).
Warning
SPIFFS partition MUST have configured “Type” as “data” and “SubType”
as “spiffs”. For example, spiffs, data, spiffs, 0x291000, 1M,
Examples:
; 1) A "partitions_custom.csv" in the root of project directory
[env:custom_table]
board_build.partitions = partitions_custom.csv
; 2) Switch between built-in tables
; https://github.com/espressif/arduino-esp32/tree/master/tools/partitions
; https://github.com/espressif/esp-idf/tree/master/components/partition_table
[env:custom_builtin_table]
board_build.partitions = no_ota.csv
Embedding Binary Data¶
Sometimes you have a file with some binary or text data that you’d like to make available to your program - but you don’t want to reformat the file as C source.
There are two options board_build.embed_txtfiles
and board_build.embed_files
which can be used for embedding data. The only difference is that files specified
in board_build.embed_txtfiles
option are null-terminated in the final binary.
[env:myenv]
platform = espressif32
board = ...
board_build.embed_txtfiles =
src/private.pem.key
src/certificate.pem.crt
src/aws-root-ca.pem
The file’s contents will be added to the .rodata
section in flash, and
are available via symbol names as follows:
extern const uint8_t aws_root_ca_pem_start[] asm("_binary_src_aws_root_ca_pem_start");
extern const uint8_t aws_root_ca_pem_end[] asm("_binary_src_aws_root_ca_pem_end");
extern const uint8_t certificate_pem_crt_start[] asm("_binary_src_certificate_pem_crt_start");
extern const uint8_t certificate_pem_crt_end[] asm("_binary_src_certificate_pem_crt_end");
extern const uint8_t private_pem_key_start[] asm("_binary_src_private_pem_key_start");
extern const uint8_t private_pem_key_end[] asm("_binary_src_private_pem_key_end");
The names are generated from the full name of the file. Characters /, .
,
etc. are replaced with underscores. The _binary
+ _nested_folder
prefix
in the symbol name is added by “objcopy” and is the same for both text and binary files.
See full example with embedding Amazon AWS certificates:
ULP coprocessor programming¶
If you want to take measurements using ADC, internal temperature sensor or external I2C sensors, while the main processors are in deep sleep mode you need to use ULP coprocessor. At the moment ULP can be used only with the framework ESP-IDF.
First of all, to use ULP in your project you need to make sure that it is enabled in your
sdkconfig.h
configuration file. The next two lines must be added:
#define CONFIG_ULP_COPROC_ENABLED 1
#define CONFIG_ULP_COPROC_RESERVE_MEM 1024
Usually CONFIG_ULP_COPROC_RESERVE_MEM
is already defined in the default
sdkconfig.h
with value 0
. You can modify this value to meet your requirements.
Secondly, all ULP code, usually written in assembly in files with .S
extension,
must be placed into a separate directory with the name ulp
in the root folder
of your project. So your project structure should look like this:
project_dir
├── include
├── lib
│ └── README
├── test
├── src
│ ├── main.c
│ └── sdkconfig.h
├── ulp
│ └── ulp_code.S
└── platformio.ini
See full examples with ULP coprocessor programming:
- https://github.com/platformio/platform-espressif32/tree/develop/examples/espidf-ulp-adc
- https://github.com/platformio/platform-espressif32/tree/develop/examples/espidf-ulp-pulse
More details are located in the official ESP-IDF documentation - ULP coprocessor programming.
Uploading files to file system SPIFFS¶
- Create new project using PlatformIO IDE or initialize project using PlatformIO Core (CLI) and platformio init (if you have not initialized it yet)
- Create
data
folder (it should be on the same level assrc
folder) and put files here. Also, you can specify own location for data_dir - Run “Upload File System image” task in PlatformIO IDE or use PlatformIO Core (CLI)
and
platformio run --target
command withuploadfs
target.
To upload SPIFFS image using OTA update please specify upload_port
/
--upload-port
as IP address or mDNS host name (ending with the *.local
).
Examples:
Over-the-Air (OTA) update¶
Using JFrog Bintray (free and secure Cloud solution)¶
- Video and presentation - swampUP: Over-The-Air (OTA) firmware upgrades for Internet of Things devices with PlatformIO and JFrog Bintray
- Demo source code: https://github.com/platformio/bintray-secure-ota
Using built-in Local solution¶
Demo code for:
There are 2 options:
- Directly specify
platformio run --upload-port
in command line
platformio run --target upload --upload-port IP_ADDRESS_HERE or mDNS_NAME.local
- Specify
upload_port
option in “platformio.ini” (Project Configuration File)
You also need to set upload_protocol to espota
.
[env:myenv]
upload_protocol = espota
upload_port = IP_ADDRESS_HERE or mDNS_NAME.local
For example,
platformio run -t upload --upload-port 192.168.0.255
platformio run -t upload --upload-port myesp8266.local
Authentication and upload options¶
You can pass additional options/flags to OTA uploader using
upload_flags
option in “platformio.ini” (Project Configuration File)
[env:myenv]
upload_protocol = espota
; each flag in a new line
upload_flags =
--port=3232
Available flags
--port=ESP_PORT
ESP32 OTA Port. Default 8266--auth=AUTH
Set authentication password--spiffs
Use this option to transmit a SPIFFS image and do not flash the module
For the full list with available options please run
~/.platformio/packages/tool-espotapy/espota.py -h
Usage: espota.py [options]
Transmit image over the air to the esp32 module with OTA support.
Options:
-h, --help show this help message and exit
Destination:
-i ESP_IP, --ip=ESP_IP
ESP32 IP Address.
-p ESP_PORT, --port=ESP_PORT
ESP32 ota Port. Default 8266
Authentication:
-a AUTH, --auth=AUTH
Set authentication password.
Image:
-f FILE, --file=FILE
Image file.
-s, --spiffs Use this option to transmit a SPIFFS image and do not
flash the module.
Output:
-d, --debug Show debug output. And override loglevel with debug.
-r, --progress Show progress output. Does not work for ArduinoIDE
Warning
For windows users. To manage OTA check the ESP wifi network profile isn’t checked on public be sure it’s on private mode``
Using Arduino Framework with Staging version¶
PlatformIO will install the latest Arduino Core for ESP32 from
https://github.com/espressif/arduino-esp32. The Git
should be installed in a system. To update Arduino Core to the latest revision,
please open PlatformIO IDE and navigate to PIO Home > Platforms > Updates
.
Please install PlatformIO IDE
Initialize a new project, open “platformio.ini” (Project Configuration File) and set platform to
https://github.com/platformio/platform-espressif32.git#feature/stage
. For example,[env:esp32dev] platform = https://github.com/platformio/platform-espressif32.git#feature/stage board = esp32dev framework = arduino
