This is not compatible with the use of the analogue input(s) for voltage or current measurements. at least one of the Australian-made Freetronics boards) and some Ethernet Shields appear to use Analog I/O for purposes connected with the Ethernet controller. Arduino CompatibilityĪrduino clones that have on-board Ethernet (e.g. '''Connect the jumper to Digital 2 for Arduino Uno/Duemilanove or Digital 3 for Arduino Leonardo.''' These pins connect to the special hardware interrupt pin INT0.įor more information on RFM12B & RFM69CW connection to Arduino, see. The setting of this jumper depends on which Arduino board the shield is connected to. ![]() The right hand solder jumper sets the RFM12B interrupt pin. ![]() RFM12B / RFM69CW Interrupt Solder Jumper Setting #if defined(_AVR_ATmega32U4_) //Arduino Leonardo If you're using an Arduino Uno (ATmega328), in the file RF12.cpp, replace the entire function "void rf12_set_cs(uint8_t pin)" with this:
