You can learn more about serial communication here. For serial debugging, youвЂ™ll need a USB cable and a USB-to-Serial adapter, and the SoftwareSerial library to send messages to a computer. To keep the bootloader size as small as possible, the bootloader only allows for USB programming. You might be thinking, вЂњBut doesnвЂ™t the USB connector provide communication between the ATtiny and the computer?вЂќ YouвЂ™re right it does. The UART is used for serial communication, whether itвЂ™s for programming or printing messages to the serial window. This is because, unfortunately, the ATtiny84 doesnвЂ™t have a hardware UART. If you hadnвЂ™t noticed in the pin description, there was no mention of RX or TX pins. The pins for the switch use the ATtinyвЂ™s internal pull-up resistors, so as long as the switch is not closed, the pin can be configured in any way youвЂ™d like without having to cut traces. The only pins that do not have a jumper on them are the pins used for the five-way switch. The bootloader uses these two pins for USB programming.Д®ach of these pins has been broken out to the edge of the board to make customization easy! If you would like to use any of these pins for something other than what itвЂ™s currently connected to, we provided jumpers that can easily be cut with a hobby knife. Missing from the list are digital pins 9 and 10. 10-bit analog-to-digital converter, which can be used on 8 pinsДЇor details about what each pin is able to do, refer to the table below.

12 I/O pins MAX (the Roshamglo breaks out 9 of these pins).

512B of SRAM, which stores our variables used in our program.

8kB of flash memory for our program (~6kB after the bootloader is installed).

The brains behind the Roshamglo is an ATtiny84, a lightweight Arduino-compatible microcontroller.

IR receiver with built-in 38kHz demodulator.

Note: This is a repeat section from the Roshamglo Hookup Guide, but it could be useful if this is the first place you've visited.

How to Install an ATtiny Bootloader With Virtual USB.If you arenвЂ™t familiar with the following concepts, we recommend checking out these tutorials before continuing. The only things youвЂ™ll need to reprogram your Roshamglo badge are a fully constructed badge and a computer. What can you make with some blinking lights, a five-way switch and IR communication? Well, how about a TV remote or a laser tag game, for starters. This will allow you to create your own applications for the badge. In addition to playing infrared (IR) Rock-Paper-Scissors, the Roshamglo board can be reprogrammed with user-created code. So youвЂ™ve put together your Roshamglo badge, and now you want more? Well, we can help you with that.
