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.
