Serial Peripheral Interface (SPI) Introduction. Serial Peripheral Interface (SPI) is an interface bus commonly used to send data between microcontrollers and small peripherals such as shift registers, sensors, and SD cards. It uses separate clock and data lines, along with a select line to choose the device you wish to talk to.
Establishment of the Committee. In February 1947, in accordance with a decision from the first session of the Commission on Human Rights (E/259), a group consisting of Eleanor Roosevelt, Pen-Chun Chang and Charles Malik, began drafting the International Bill of Human Rights.
The Universal Declaration of Human Rights was adopted by the United Nations General Assembly resolution 217A at its 3rd session in Paris on 10 December 1948. From 1946-1948 delegates to the United Nations discussed and drafted an international declaration on the subject of human rights that has become a standard of principles for human rights. This website provides access to United Nations documentation related to the drafting of The Universal Declaration of Human Rights.
