The Attiny 13a
Description of the feet
Sensor of vibration
switching reaction modes to the vibration sensor
– Swiodiod “+”
The transistor “+”
- the output (A) duplicates the LED but "-"
The conclusion (b) “-”
Food and land accordingly.
by the button switch the display options of the sensor state to the LED and the transistor
The committee will discuss the possibility of minimizing energy consumption.
Client's review of cooperation with freelancer
The Attiny 13aExcellent performers, skilled - a true specialist who is in his place
He made a lot of things for himself in the communication process.
The project is done as they say “without a shell”
I recommend cooperation
Freelancer's review of cooperation with Oleg Gudimov
The Attiny 13aThe only thing I had to work hard on is to make a more or less comprehensible TZ. In the rest, only positive impressions: Oleg responds to questions in time and responds adequately to the comments on the project.

408 12 1 Hi, the project is yet understood not to the end, with mc Attiny13 I have work experience, I have all the necessary elements for the scheme, except the vibration sensor, but I as understood it does not represent anything complicated, in the extreme case it can be imitated, I also need to understand the idea and principle of the operation of the device. If you are interested we will be able to discuss all of this, it will be conditioned with the scheme, I think with the intrinsic programming everything will be OK, and start the drafting of the project. I work at Atmel Studio, if I need Proteus for virtual tests, I will be able to develop a scheme and a stamp. Write to LS, I’m ready to cooperate and in any case I’ll be happy to discuss the proet.

12 Hello to you. I have been working with microcontrolers for over 20 years. He developed medical equipment. This work was done with the ATiny25 microcontroller. What is the deadline for implementation of the project? What a budget?

Вопросы:
- модель или тип датчика вибрации
- Что за транзистор? Чем будет управлять?
- Что означает "вывод (А) дублирует светодиод но "-"" ?
- Что означает "вывод (В) "-"" ?
Возможность внутрисхемного программирования: у attiny13a всего 8 выводов.
2 вывода - питание.
остаётся 6 выводов.
1 вывод - reset - если оставлять возможность программирования через ISP, то его не переназначаем.
остаётся 5 выводов.
Из этих 5-ти выводов 3 используются так же для программирования.
Допустим к одному можно подключить светодиод.
Если к ним подключить кнопку, датчик вибрации или транзистор - на время прошивки их нужно физически отключать.
Так же будет 2 вывода, не задействованные в интерфейсе для программирования.

Почему рассматривается attiny13a? Хватит ли его для выполнения предполагаемого алгоритма?
Есть МК avr с большим количеством выводов и ресурсами.
Attiny44, Attiny84 - например.
Есть STM32L - как раз для задач с низким энергопотреблением.
-
это всё тот же девайс, что целый год не можете сделать, или же что то новое?
