DigiSparks

DigiSparks

Once again, in about 2019, eBay suggested I buy some DigiSparks. At the price suggested, 1.69 GBP, it was worth a go. They sat in my box of bits, awaiting a use.

The serial Port example did not work but the keyboard example did.

The Arduino documentation has a USB keyboard example.

https://github.com/arduino/ArduinoCore-mbed/blob/main/libraries/USBHID/examples/KeyboardRaw/KeyboardRaw.ino worked.

There was a similar example for the DigiSpark.

They are super for HID keyboard automation. I have needed to reflash the bootloader once or twice.

AutoType describes using two to type across a service where both people TYPE and READ their conversation.

update on installing - a work around

Note ( 2024-09-01 ): http://digistump.com is refusing connection. So the examples about installing below need updating.

See this: https://github.com/digistump/DigistumpArduino/issues/167

This is used in preferences instead.

Original help on installing DigiSpark - needs updating

In the box labelled "Additional Boards Manager URLs" enter: http://digistump.com/package_digistump_index.json

As the link above no longer, works try:

I cannot get the DigisparkCDC examples to work

The DigiSparkCDC examples do not work. They Blue screened my Win10 PC back in 2019. On 2024-09-01 they compile, but Windows complains that Windows does not recognise the Device.

Use a Leonardo instead.

Update problem due to old ADSL router

I got this when using the board manager and Win10: "CRC error, file corrupted. Try to repeat later"

This helped. https://github.com/arduino/Arduino/issues/9719

I deleted C:\Users\doug\AppData\Local\Arduino15\library_index.json

When I next opened the IDE it seemed to have installed the new boards.

	C:\Users\doug\AppData\Local\Arduino15\library_index.json
	~/.arduino15/library_index.json

Another may be related problem. The iPhones would not take any updates and failed.

My ISP suggested I upgrade and it seemed to fixed the iPhone update issue.

My old ADSL2 router was replaced by a router that supported FTTC.

I installed DigiSpark into the Arduino IDE over the new router onto a new Windows computer with no issues.
