This is the third post of my series documenting the development of a custom firmware for the FS-i6s transmitter. In my previous post i wrote about how to connect to the target using the DFU bootloader mode. This time we will use a different way to connect to the STM32F0: We will connect a ST-Link… Read More »
This is the second post of my series documenting the development of a custom firmware for the FS-i6s transmitter. See my previous post for details about the used parts and the pinout. DFU Bootloader The STM32F0 has a nice feature: An on-board, un-brickable DFU bootloader. This bootloader can be entered by the following sequence: remove… Read More »
This is the first post of my series documenting the development of a custom firmware for the FS-i6s transmitter. Components In order to write a custom firmware for the Flysky FS-i6s transmitter we will need to know which components are used and how they are connected. So let’s take a look at the PCB: CPU… Read More »
