@brief Support for the limifrog-v1 board
|
|
|
|
## Overview
|
|
LimiFrog-v1 arose from the La BlueFrog board. LimiFrog-v1 contains the first
|
|
hardware revision of that kickstarter project. LimiFrog-v2 is already there and
|
|
the RIOT support will follow.
|
|
[LimiFrog](https://github.com/LimiFrog/LimiFrog-HW)
|
|
features a variety of sensors as well as an OLED Display and a BLE
|
|
(Bluetooth Low-Energy) module.
|
|
|

## Flashing and Debugging the device
|
|
|
|
The LimiFrog-v1 has no on-board programmer nor an USB-UART converter. It can
|
|
be programmed by using the integrated ST-Link/V2 programmer of any STM32Fx-
|
|
discovery board. See the Hardware subsection in Flashing and Debugging section
|
|
[here](@ref boards_yunjia-nrf51822) for an example.
|
|
Another way is to use a stand-alone ST-Link V2 programmer as shown in the
|
|
picture.
|
|
|
|
|
|
|
|
|
|
To debug the device you may also want to use a stand-alone UART converter and
|
|
connect it to the pins PC10 and PC11 and keep the programmer plugged.
