Admin — Thu, 16 May 2013 21:26:00 GMT

Simple PCB for CMSIS-DAP debug adapter. Additional serial (UART) interface.

Compatible with Keil ARM. Available on Github (Eagle files and codes).

Provide USB HID (for debug) and USB Serial (for messages) on STM32F103C8 chip.

Router device (continue EzMacPro - STM32 & EFM32)

First post about small device for home automation and meerkats control station.

Test only with RFM22B and STM32F103CB.

Now device photo

and complete in a box

Now i use STM32L151 (5-6uA in sleep mode) but also test EFM32 (2 uA sleep).

Ported EzMacPro stack provide P2P network (many base stations with many end-devices) or star (single base station) network.
I plan use for home automation, simple car show control system and for wild animal control application.

Build-in accelerometer provide device self control for movement (legal or not). Together with microSD device can record data from remote (end) device for long time w/o use GSM(GPRS) and WiFi.

Many thanks USR company for WiFi-USART module (based on EFM32 chip - so extremely low consumptions). This module provide easy access from any end-user device to this router (now i make a simple Android application to control and visualize some data)

Telit Terminal

I use RSTERM software from roundsultions for programming Telit modules (GE863, GE865, GM862).

But this program don't work with budget CP2102 USB-serial convertor.
This simplest terminal program works with serial port via serial port class from .NET framework.
