NO compatible board e g OLIMEXINO 328 OLIMEXINO STMB2 PIC32 PINGUINO Electrode cable The pinout for the board strictly follows the DUINO extension specification Best choice for a board would be OLIMEXINO 328 or any DUINO board which utilizes the ATmega328 since we have working and tested examples for those MCUs configuring them for ATmegal28 would require tweaking of the code The cable features three electrodes two data electrodes 1 channel and DLR electrode feedback If you use more than one SHIELD EKG EMG you can use cables without DLR for every shield after the first IMPORTANT NOTE The electrode cables for SHIELD EKG EMG and MOD EEG SMT differ from each other In case you want to build a working SHIELD EKG EMG system without owning a DUNIO board the best choice would be our board OLIMEXINO 328 This is the web page for the board http www olimex com dev olimexino 328 html 2 3 Powering up the board Page 6 of 18 OLIMEX 2012 SHIELD EKG EMG The SHIELD EKG EMG board is powered by the host board it is mounted on There is the option to be powered either by 3 3V or 5 0V host board configured easily by a jumper On powering the board PWR LED must become GREEN 2 4 Arduino Maple Pinguino note What is Arduino Arduino is an open source electronics prototyping platform designed to make the process of using electronics in multidisciplinary projects more accessible The hardware consists of a simple op
6. R technology the computational power of Arduino boards is modest this is why a team from MIT developed the MAPLE project which is based on ARM7 STM32F103RBT6 microcontroller The board have same friendly IDE as Arduino and offers the same capabilities as hardware and software but runs the Arduino code much faster The Maple project can be found at http leaflabs com In parallel with Arduino another project was started called PINGUINO This project chose its first implementation to be with PIC microcontrollers as AVRs were hard to find in some parts of the world like South America so it is likely to see lot of PINGUINO developers are from that part of the world PINGUINO project founders decided to go with Python instead Java for processing language For the moment PINGUINO is much more flexible than Arduino as it is not limited to 8bit microcontrollers Currently the IDE which has GCC in Page 7 of 18 OLIMEX 2012 SHIELD EKG EMG background can support 8 bit PIC microcontrollers 32bit PIC32 MIPS microcontrollers and ARM7 CORTEXMS microcontrollers which makes PINGUINO very flexible because once you make your project you can migrate easily through different hardware platforms and not being bound to a single microcontroller manufacturer The PINGUINO project can be found at http www pinguino cc Page 8 of 18 OLIMEX 2012 Here you get acquainted with the main parts of the board Note the names used on the board differ from the name
