Espressif 32

Configuration

platform = espressif32

Espressif Systems is a privately held fabless semiconductor company. They provide wireless communications and Wi-Fi chips which are widely used in mobile devices and the Internet of Things applications.

For more detailed information please visit vendor site.

Configuration

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 Espressif IoT Development Framework:

[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 pio run --target the next command to erase the entire flash chip (all data replaced with 0xFF bytes):

> pio run --target erase

# or short version

> pio run -t erase

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:

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

Note

In case with ESP-IDF, these files also need to be specified in CMakeLists.txt using the target_add_binary_data function.

The file 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.

Note

With the ESP-IDF framework symbol names should not contain path to the files, for example _binary_private_pem_key_start instead of _binary_src_private_pem_key_start.

See full example with embedding Amazon AWS certificates:

Uploading files to file system SPIFFS

  1. Create new project using PlatformIO IDE or initialize project using PlatformIO Core (CLI) and pio project init (if you have not initialized it yet)

  2. Create data folder (it should be on the same level as src folder) and put files here. Also, you can specify own location for data_dir

  3. Run “Upload File System image” task in PlatformIO IDE or use PlatformIO Core (CLI) and pio run --target command with uploadfs 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 built-in Local solution

Demo code for:

There are 2 options:

pio run --target upload --upload-port IP_ADDRESS_HERE or mDNS_NAME.local

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,

  • pio run -t upload --upload-port 192.168.0.255

  • pio 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/framework-arduinoespressif32/tools/espota.py --help

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.
    -I HOST_IP, --host_ip=HOST_IP
                        Host IP Address.
    -p ESP_PORT, --port=ESP_PORT
                        ESP32 ota Port. Default 3232
    -P HOST_PORT, --host_port=HOST_PORT
                        Host server ota Port. Default random 10000-60000

  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
    -t TIMEOUT, --timeout=TIMEOUT
                        Timeout to wait for the ESP32 to accept invitation

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``
