You can open main.cpp to change the program. For example, use the following code to blink the LED every 0.1s
#include "mbed.h"
DigitalOut led(p30); // on-board led is connected to p30
int main()
{
while (true) {
led = !led;
wait(0.1);
}
}
Note
If you are get a compiling error that 'device.h' is not found, try to update the mbed library to the latest revision in your program.
Color Pixels, a colorful LED strip, can be controlled by mobile phone.
Make it run
If you want to change the program, click this link to import the Color Pixels program to mbed online IDE.
If the BLE device is disconnected frequently, we can improve the stability by changing the BLE parameters - Advertising Duration (main.cpp), Min Interval and Max Interval (nRF51822/projectconfig.h)
#define CFG_GAP_CONNECTION_MIN_INTERVAL_MS 20 /**< Minimum acceptable connection interval */
#define CFG_GAP_CONNECTION_MAX_INTERVAL_MS 200 /**< Maximum acceptable connection interval */
You can use the Arch Link as a web dashboard.
You can also use the Arch Link as a Mobile APP dashboard.
