I want to develop hart protocol using AD5700. I've some queries,
Is it necessary to purchase below mentioned things from HARTComm,
1. HART license?
2. HART special code?
3. HART annual membership?
CN0267 shows a reference design for a complete 4-20mA loop-powered field instrument/transmitter with HART interface. This design uses the ADuCM360 microcontroller, AD5421 loop-powered DAC and AD5700 HART modem. It does not provide the HART stack. A basic code example that demonstrates the functionality and performance of the circuit can be found in the CN-0267 Design Support Package.
