Recently I received a A-Star 32U4 mini board from Pololu, which I’d bought during the Black Friday for just $6. Since this mico-controller board shares many similarities with Arduino Leonardo, I thought I could just upload the program using Arduino IDE by selecting Arduino Leonardo as the board type. Unfortunately, that did not work even after I tried resetting the board as suggested in the following the error message logged by Arduino IDE in the console:...
My USBAsp dongle arrived from China. It’s connected to the ISCP pins on an Arduino Nano, and also plugged to a computer via USB connection. According to lots of intructions on the Internet, to upload a sketch to an Arduino, we need to do the following: Tools -> Programmer -> USBasp File -> Upload Using Programmer Unfortunatly it did not work. Here is the error message produced by Arduino IDE:...
In the past few weeks, I noticed that data transmitting from one of sensor nodes got dropped dramatically. This sensor node is an Arduino Micro using nRF24L01+ as the transmitter. Well, it’s supposed to send data to the base station once every 30 seconds; however the transmitting recurrence time exceeded 2 minutes. By default the transmitting rate is at 1 Mb/s, so I dropped it to 250 Kb/s to see if had any better improvement....
