Board: ESP32-DEVKIT1
Got this board to play around with…
- esp32_devkit1.txt
-------------- ESP32-DEVKITV1 -------------- - clone of DOIT's ESP32 DEVKIT V1? - ESP-WROOM-32 (ESP32-D0WDQ6) = ESP32-D0WD-based modules with integrated flash - DECISION20200822: = toolchain and build environment is simply not worth it! = WILL USE micropython instead! ----------- micropython ----------- - get some tools > pip install esptool rshell - download binary from https://micropython.org/download/esp32/ = selected esp32-idf3-20191220-v1.12.bin = idf4 seems to be missing LAN? stick with idf3 for now... - erase flash > esptool.py --chip esp32 --port /dev/ttyUSB0 erase_flash - flash micropython > esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 460800 write_flash -z 0x1000 <bin> - use rshell to manage code (vfs) > rshell --port /dev/ttyUSB0 --buffer-size=32 - download file in rshell > cp <file> /pyboard[/<more_path>] ---------- board info ---------- esp32 doit devkit v1 vid = 0x10c4 pid = 0xea60 sn = 0001 esp32 doit devkit v1 (aliexpress - usb type c) vid = 0x1a86 pid = 0x7523 sn = (null)
Decided to use micropython. Pinouts shown below (Disclaimer: Image copied from RandomNerdTutorials).
(Disclaimer: Sorry, I can't remember where I got the following two from…).
Below is a simple python script to test SSD1306 OLED display which makes use of this micropython library code.
- test.py
from machine import Pin, I2C from ssd1306 import SSD1306_I2C from time import sleep def run_this(): i2c = I2C(-1, scl=Pin(22), sda=Pin(21)) oled_width = 128 oled_height = 64 oled = SSD1306_I2C(oled_width, oled_height, i2c) oled.text('Hello, World 1!', 0, 0) oled.text('Hello, World 2!', 0, 10) oled.text('Hello, World 3!', 0, 20) oled.show()
Using Arduino IDE:
- select
Preferences>Additional Board Manager URLs
- enter
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json.
- open
Boards Manager
and install esp32 (search for it) - when selecting board for upload, select
DOIT ESP32 DEVKIT V1
Note: esp32 flash tool requires python serial module (e.g. pip install pyserial
)
Board: ESP01S
