Galvanic isolation of the 1-Wire protocol.
45 USD Client's review of cooperation with Ruslan Lobus
Galvanic isolation of the 1-Wire protocol.Task completed quickly and professionally.
Freelancer's review of cooperation with Stanislav Zhuravlov
Galvanic isolation of the 1-Wire protocol.Great client. Understands technical issues, so sets tasks clearly and understands all the complexities of its implementation. Compensates for costs of radio components. Is accommodating when complications arise.

I will use the ADuM5241, but I will replace the pseudo-logic with field-effect transistors by the 74HC00 logic. This will increase the speed, reduce the number of components in the circuit, and eliminate the need to adjust resistors for a specific platform. It will be necessary to order the ADuM chip for me. The deadline includes the delivery time of the radio components.

Доброго дня. Я можливо не зрозумів суть. Тут юарта немає, що ви хочете гальванічно розв'язати?

Хочу розв'язати Vout,data,gnd.

скажите цель данного действа? может там не 1 вире нужно развязывать.

Мета - розв'язати датчик. Саме 1wire.

Це 1 ware через UART. Передача та читання через rx, tx. А не через один пін. Мені не підходить.

или вот 1wire==1wire

Ну да, кругом зрада.
Не туда воюете.

Це розв'язка i2c. Пробував, не працює.
Може я щось не так робив.

Повинна працювати. Це геніальне рішення. Коли Мастер дає "0", то Т2 підтягує зворотній звязок до "1" і, тим самим, вимикає його. Коли Мастер "1", а Слейв дає "0", то Т1 підтягує прямий звязок до "1" і, тим самим, вимикає його. Ше й живлення на борту.
