WebInterrupts in MicroPython will be higher latency than those in C. And C interrupts are slower than polling from C. CircuitPython's hardware APIs are geared to doing the timing critical tasks in the best way for a particular platform. (Usually using a chip peripheral and DMA or C interrupts. For the RP2040, we'll use the PIO as needed for example.) WebInterrupt¶. The Interrupt class represents a single interrupt pin in the block design. It mimics a python Event by having a single wait function that blocks until the interrupt is …

WebJul 1, 2024 · It increases the interrupt period (at 1A) from 600µs to around 0.6 seconds. Now the 12ms (at 50mA) has become 12.2 seconds. That’s the time between pulses (interrupts) to your circuitry. Should the circuit draw less than that maximum of 1A, then this time will be even longer.
