Microduino-smartRF

Microduino smartRF uses the latest high-performance CC1101 wireless communication chip, which can be widely applied to various short distance wireless communication field

Features

• With highest working rate at 500KBPS, it supports 2-FSK, GFSK and MSK modulation;
• Capable of modifying baud rate, power, frequency and other related parameters by software;
• High sensitivity (Under 1.2KBPS - 110dDm, 0.1% packet error rate);
• Low power consumption (1.2 KBaud,433 MHZ RX is 15 ma);
• Built-in hardware CRC error detection and point-to-multipoint communication address control;
• With programmable and controllable power output，the maximum power is +10dBM;
• It owns wireless wake up function and supports low power electromagnetic wave activation function;

Specification

Development

Application library downlaod: https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_03_Microduino_SmartRF_CC1101

Test program download： https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Texting/Microduino_SMARTRF

Application

You can download the test program that Microduino offers, and use the Microduino-OLED module to test Microduino-smartRF.

• Prepared Hardware: Microduino FT232R, Microduino Core and Microduino-smartRF;
• Prepared Software: Microduino's test program (Arduino), Arduino IDE (upper to 1.0 release);
• Two Microduino-Core modules.

By Microduino-smartRF communication test, the host machine sends the runtime to the auxiliary machine, which will be displayed on the OLED ;

• • ceshi_SMARTRF_T is the program sent by the host machin and ceshi_SMARTRF_R is the program sent by the auxiliary machine;
  • The host machine needs Microduino-Core and Microduino-smartRF modules and the auxiliary machine needs Microduino-Core, Microduino-smartRF and MIcroduino-OLED as well as Microduino FT232R used to download program;
  • Use the IDE to open the test program and then upload the program to the host and auxiliary machine respectively;
  • After the upload, "Rec. pack #xx" will be displayed on OlED, and "xx" is the time that is sent from the host machine;
  • Restart the host machine and start timing from zero, the data of the auxiliary machine will be also updated at the same time.

FAQ

• Do you have module to support CC2511 or CC2500?
  • So far we don’t have this module.
