On Linux, you might try running the Arduino software as root, at least temporarily to see if fixes the upload. if you’re using them to read data over the USB or serial connection to the Arduino board. (First try to hook that arduino to another machine to make sure it at least recognizes it is there - to rule out a bad Arduino): On Windows, if the software is slow to start or crashes on launch, or the Tools menu is slow to open, you may need to disable Bluetooth serial ports or other. You may need to quit Processing, PD, vvvv, etc. Here are the serial port troubleshooting suggestions. Make sure you don’t have firewall software that blocks access to the serial port (e.g. from Sprint or Verizon), PDA sync applications, Bluetooth-USB drivers (e.g.
That is a full 25 of the available RAM for your entire sketch. The Arduino software scans all the serial (COM) ports on your computer when it starts and when you open the Tools menu, and these networked ports can sometimes cause large delays or crashes.Ĭheck that you’re not running any programs that scan all serial ports, like USB Cellular Wifi Dongle software (e.g. With two separate serial port buffers (on for Tx, one for Rx), changing the buffers from 64 to 256 bytes increases the RAM requirements from 128 bytes to 512 bytes.
On Windows, if the software is slow to start or crashes on launch, or the Tools menu is slow to open, you may need to disable Bluetooth serial ports or other networked COM ports in the Device Manager.
