Gpio maximum output speed
WebJul 21, 2024 · To get 10 MHz at an output you'd need to clock the core at a multiple of 10 with the PLL, since you can't divide the clock by 7.2 at the timers. The datasheet number maximum Fmax (IO)out of 50 MHz is the hardware limit. The GPIO hardware cannot achieve a slope fast enough to go higher. You can configure the slew rate of outputs, for … 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.

WebJan 12, 2024 · The STM32F103C8 runs at a maximum clock speed of 72 MHz. So 36 MHz is the maximum frequency that can be generated on a GPIO as a separate clock cycle is needed to set and clear the pin. This frequency can only be achieved with a timer. If you try the same with code, you will need at least three instructions: two stores and one branch.
WebMay 5, 2024 · In that case, a arduino will be fine. A arduino is already PIO buit-in , just use the same output of the PIO and connect the same way to the arduino. Let say for example you use 8 output going to the robot, than use 8 output pin of the ardiuno and program the arduino.
