 ## Usage:
 
 * [Install](/timonel-bootloader/README.md#Installation) "timonel.hex" on a Tiny85 (bare chips or Digisparks).
-* Build your application program as usual, then use "[tml-hexparser](/timonel-hexparser)" to convert the ".hex" file into a byte array to be included in "[timonel-twim-ss.bin](/timonel-twim-ss)" or "[timonel-twim-ms.bin](/timonel-twim-ms)".
-* Use [VS Code](http://code.visualstudio.com) + [PlatformIO](http://platformio.org) to compile and install "[timonel-twim-ss.bin](/timonel-twim-ss)" or "[timonel-twim-ms.bin](/timonel-twim-ms)" (containing the payload) in an arduino-compatible MCU. It has been tested with ESP8266 ESP01 and NodeMCU. **Note:** The supplied ".bin" file contains a small payload demo that blinks PB1 on the Tiny85.
+* Build your application program as usual, then use "[tml-hexparser](/timonel-hexparser)" to convert the ".hex" file into a byte array "payload.h" to be included in the "data/payloads" folder of "[timonel-mss-esp8266](https://github.com/casanovg/timonel-mss-esp8266)" or "[timonel-mms-esp8266](https://github.com/casanovg/timonel-mms-esp8266)".

It has been tested with ESP8266 ESP01 and NodeMCU. **Note:** The supplied ".bin" file contains a small payload demo that blinks PB1 on the Tiny85.
 * Connect both chips by **I2C** (SDA, SCL and ground).
 * Open an asynchronous terminal (e.g. [MobaXterm](http://mobaxterm.mobatek.net)) connected to the serial port of the I2C master (115200 N 8 1).
 * Run the "timonel-twim-ss" commands shown on screen for erasing and flashing new firmware on the Tiny85.
 * It is also possible to update the bootloader itself by using "[timonel-updater](/timonel-updater)" (based on the micronucleus upgrade program).

+
+#### Libraries
+
+* **[Nb_Micro](https://github.com/casanovg/Nb_Micro)**: Arduino library to control devices that implement the NB command set over an I2C bus.
+* **[Nb_TimonelTwiM](https://github.com/casanovg/Nb_TimonelTwiM)**: Arduino library for uploading firmware to a microcontroller running the Timonel bootloader. It uses the NbMicro library to access the I2C bus.
+* **[Nb_TwiBus](https://github.com/casanovg/Nb_TwiBus)**: Arduino library to scan the I2C bus in search of connected devices addresses and data. It uses the TimonelTwiM library bootloader object definition.
+* **[nb-twi-cmd](https://github.com/casanovg/nb-twi-cmd)**: NB TWI (I2C) command set.
+
+#### Demo I2C master test applications
+
+* **[timonel-mss-esp8266](https://github.com/casanovg/timonel-mss-esp8266)**: Timonel I2C master **single slave**. Serial console-based application that allows sending commands to a device that runs the bootloader from an ESP8266.
+* **[timonel-mms-esp8266](https://github.com/casanovg/timonel-mms-esp8266)**: Timonel I2C master **multi slave**. Serial console-based application that runs a loop that flashes, deletes and runs a user application on several Tiny85's running the bootloader from an ESP8266.
