Speeding Up BeagleBone Black GPIO A Thousand Times

Web69% faster. REG_READ. 505ms. 69% faster. That's 50 nanoseconds per operation at the fastest speed! Other notes: IRAM_ATTR on setup (or putting it in another function) did not seem to make a difference. Creating these functions as a task on another core didn't seem to make a difference, even set to high priority. WebThe max pin toggle frequency I get is around 230 KHz. Since the MCU can be run at 84 MHz, I have a feeling, that it's possible to increase the max toggle frequency beyond 230 KHz.

"WebIt is slightly different than for the AVR chips. There is one register for setting the pins to HIGH and another one to set the pins to low. Setting the pin HIGH: GPOS = (1 << PIN_OUT); Setting the pin LOW: GPOC = (1 << PIN_OUT); using this, I managed to speed up my code by a factor of three. It is not as dramatic as for the AVR chips, since the ... " - Gpio_speed_fast

A general-purpose input/output (GPIO) is an uncommitted digital signal pin on an integrated circuit or electronic circuit (e.g. MCUs/MPUs) board which may be used as an input or output, or both, and is controllable by software. GPIOs have no predefined purpose and are unused by default. If used, the purpose and behavior of a GPIO is defined and implemented by the designer of higher assembly-level circuitry: the cir…

WebMay 5, 2024 · Short answer: yes, easily. Slightly longer answer: 125 IOs / second * 20 = 2500 / second. A standard Arduino runs at 16 Mhz, which means it has 6400 clock cycles to do what you need. Even the (relatively) slow digitalWrite () command takes only about 17 clock cycles, leaving you lots of time to do other stuff. crystal river fire departmentWebApr 22, 2024 · Inexpensive: ~$2 for the cheapest breakout boards - "Bluepill" and a reusable ST Link V2 clone programmer.
