Does SPI have one master?
Does SPI have one master? SPI devices communicate in full duplex mode using a master-slave architecture with a single master. The master device originates the frame for reading and writing. Multiple slave-devices are supported through selection with individual slave select (SS), sometimes called chip select (CS), lines. Can I2C have multiple masters? The I2C component […]
What is ferritic and austenitic steel?
What is ferritic and austenitic steel? Ferritic stainless steels are magnetic, while austenitic stainless steels in the annealed condition are not. When the austenite converts to martensite, strength increases, ductility increases, and the structure becomes magnetic. What is ferrite stabilizer? The ferrite stabilizers are chromium, silicon, molyb- denum and columbium. It is the balance between […]
What is the main general purpose of negative feedback?
What is the main general purpose of negative feedback? Negative feedback occurs when a system’s output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body’s homeostasis. […]
