DigiSpark mini Arduino ATtiny85 module, commissioning, test
P0 (SDA, PWM, AREF)
P1 (PWM, LED)
P2 (D / A, SCK)
P3 (D / A, USB +)
P4 (D / A, PWM, USB-)
P5 (D / A)
Integration with Arduino:
We choose:
File-> Preferences-> field Additional URLs to the tile manager, add the line:
http://digistump.com/package_digistump_index.json
Tools-> Tile> Tile manager-> search for "digistump" and install Digistamp AVR Boards library.
We download and install the driver for the device:
https://github.com/digistump/DigistumpArduino/releases/download/1.6.7/Digistump.Drivers.zip
After installation, select Tools-> Board-> Digispark (16.5MHz)
Loading the program is different than with standard Arduino boards:
-compile the program and start uploading
-when appropriate information appears in the console, connect the Digispark board
Let's open the example of DigiSparkUSB-> DigiScope
We compile the example and upload it to the board.
The analog signal is given on P2 (input voltage range 0-4.75v).
Using the tools https://github.com/digistump/DigisparkExamplePrograms (DigiUSB -> windows -> digiscope.exe) we can observe the analog signal given on pin P2. The 1Hz waveform is recorded below.
Depending on the program, digispark, when connected to USB, can emulate a keyboard (example with an I2C scanner), mouse, joystick, serial port. The advantage of the module are small dimensions, the disadvantage may be a small number of pins, and the layout of pins that makes it difficult to use the module on the contact plate. Earlier digispark versions were available on PCBs with a track pattern forming a USB plug, which allowed the PCB to be directly inserted into the USB socket.
What are your applications for digispark modules?

Hello. In my cellar, I will probably use the pressure sensor in the water system and then further data in series, can also be suitable for a water level sensor. [Read more]
I don't know about you, but I had problems with the digispark at the start. In most cases, the computer did not recognize the device. After replacing the diodes zener at 3.3v the problem is gone. [Read more]
For me, it often does not recognize this plate. Sometimes it takes a lot of patience to upload the program. [Read more]
@ oskar777 between the basement, the sensor and the apartment, it is worth using something like RS-485, or something equally "far-reaching". @RigelInOrion @ noel200 i.e. simplification of the... [Read more]
Isn't it better to try something like this? https://www.tme.eu/pl/details/attiny416-xnano/zecja-do-ukladow-microchip/microchip-technology/ Built in DEBUGGER and serial port via USB, full... [Read more]
Do you know any way how to run Digispark under WIN10? [Read more]
@ leonow32 interesting board, presentation of a new ATtiny series microcontroller. @pir the description in the first post was made during trials on WIN10. [Read more]
The bootloader, which is responsible for loading the program, starts only for a moment emulating the "Digispark something" device and if nothing is sent to it, it starts the program. Hence, it is constantly... [Read more]
Blue Pill costs 3 times less, offers 10 times more and is "a little" faster. Added after 1 [minutes]: The voltage on the USB lines must not exceed 3.6V. As it is bigger, errors can occur. [Read more]
This board and this microcontroller are a bit of nonsense. Who needs a USB microcontroller with such a small number of pins? In addition, the USB eats 2 ports ... The ADC is there, but it eats the port... [Read more]
@nowyARM - bluepill is "dumped". Neither I nor you will buy the STM32F103 itself at the price at which this module is sold. What "economic magic" is behind it, I have no idea, GD32 probably not, although... [Read more]
There are 6 pin uC, where 2 is power. Used in intelligent optical sensor. uC 8 pin are often used in models where miniaturization is important. In model railroads, model airplanes. [Read more]
It is not expensive ;) the original Arduino Uno costs about PLN 91 :P and you will not experience debugging there https://www.tme.eu/pl/details/a000066/zecja-arduino/arduino/arduino-uno-rev3/# ATiny416... [Read more]
Recently, I had to disassemble an oral-b vitality electric toothbrush because the switch did not work as it should. There is a microcontroller inside. Not in the plcc44 housing, but a tiny one. This is... [Read more]

You started comparing the small ATina board to the STM32 board :P [Read more]
I compared retail prices. I can also compare the price of the tile with a small AtTina for PLN 45.51 (PLN 37.56 net) with NUCLEO for PLN 55 gross. For 20% more, we have 100 times better set. Let's... [Read more]
Even in aviation models, the weight of the microcontroller itself does not matter as long as we are talking about SMD. The antenna itself from the receiver weighs a lot more, and no one in modeling cares... [Read more]
It is worth remembering that USB is not hardware-based, but software-based, which significantly limits the capabilities of such a USB. As for the AREF, it can be used, but you can also select internal... [Read more]
