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.) WebJan 30, 2024 · Interrupts are handled by parts of software called Interrupt Service Routine (ISR). When an interrupt occurs, the CPU starts executing code within this routine. When the task in the routine is completed, the processor continues executing code from where it left off.

WebApr 12, 2024 · A microcontroller is a compact integrated circuit designed to perform specific tasks within an embedded system. It typically consists of a processor, memory, and input/output (I/O) peripherals that work together to control and execute tasks. A single microprocessor has most of the in-built embedded system component requirements. 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. liteon lch-256v2s specs
