WebJul 15, 2024 · Arduino Uno is an AVR ATmega328P MCU-based development board with six analogue input pins and 14 digital I/O pins. The MCU has 32kB ISP flash memory, 2kB RAM and 1kB EEPROM. The board provides the capability of serial communication via UART, SPI and I2C. The MCU can operate at a clock frequency of 16MHz. In this … WebMay 5, 2024 · Since an Interrupt must be at least several instruction cycles long (and is usually more like 20, even if it doesn't do anything), the max frequency for a timer interrupt is much lower. (technically, I guess the processor could generate interrupt "events" at 8MHz, but it would only be able to service a fraction of them.)
WebFeb 18, 2015 · If the Arduino UNO's master clock frequency is 16MHz, and the SPI setup function setClockDivider () is used to divide the master clock by 2, that's 8MHz. Divide by 3 and you get 5.333MHz. Divide by 4, that's 4MHz. Divide by 5, that's 3.2MHz. There's no way to get a clock frequency that's between these discrete steps.
