Those of you who want to do this using Window's 8/10: Window Command Prompt cd to the directory. 1) 'stm32flash.exe COM9' replace COM9 with your COM port number. 2) 'stm32flash.exe -k COM9' This will unlock your shield. 3) 'stm32flash.exe -f -v -w motor_shield.bin COM9' This will flash the bin and re-lock the shield. The Adafruit BME280 sensor library supports passing in alternative GPIO pins from the default D2 (GPIO 4) and D1 (GPIO 5) for SDA and SCL respectively for the Wemos D1 Mini. Since the I2C is software driven on the D1 Mini, it is reasonably straight forwards to assign different ports. Ports D6 and D7 line up well with the particular BME280

I2C help, please. Using Arduino Programming Questions. SteveMann August 4, 2019, 4:19am #1. I have a Wemos d1 mini (master) that sends a filename over I2C to an Arduino Uno with an Adafruit Audio Shield. If the Uno finds the wav file on the SD card, it plays the file. Works great.

This post describes how to install the board support package for the WeMos D1 Mini board into the Arduino IDE and blink the board's LED. Note A WeMos D1 Mini clone: "IZOKEE D1 Mini NodeMcu Lua 4M Bytes WLAN WIFI Internet Development Board Base on ESP8266 ESP-12F for Arduino, 100% Compatible with WeMos D1 Mini" from [amazon] was used in this example. Description from Amazon: This D1 mini module
D1 R32 – ESP32. An Esp32 micro-controller in an Arduino Uno footprint. This is a powerful little development board with WiFi and Bluetooth capabilities. Best of all it’s easy to program using the Arduino IDE. Just follow this tutorial here for the full step-by-step instructions on programming ESP32 with Arduino IDE.
