Application
You can download the test program that Microduino supplied, 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 cores use the Microduino-smartRF to communicate, master machine sends the running time to slave machine and use the OLED to display;
- ceshi_SMARTRF_T is the master machine send program, ceshi_SMARTRF_R is the slave machine receive program.
- Master machine needs Microduino Core and Microduino-smartRF module; Slave machine needs Microduino Core, Microduino-smartRF and MIcroduino-OLED. Microduino FT232R use to download program.
- Use the IDE to open the test program and download to master and slave machine respectively.
- After download, OLED will display "Rec. pack #xx", ”xx” is the time that receives from master machine;
- Restart master machine, timing starts from zero, slave machine's data also updates at the same time.
