1. Overview The SEP5 Driver is a specialized software interface designed to facilitate communication, control, and data exchange between a host system (e.g., Linux, RTOS, or embedded firmware) and the SEP5 hardware module. Built for reliability and low-latency operations, the driver abstracts low-level register manipulations and bus protocols, providing a clean API for upper-layer applications.
// Initialize SEP5 at address 0x50 on I2C bus 2 sep5_handle_t dev = sep5_init(SEP5_I2C, 2, 0x50); // Configure sensor mode sep5_config_t cfg = .mode = SEP5_MODE_CONTINUOUS, .sampling_rate = 1000, // Hz .buffer_size = 256 ; sep5_configure(dev, &cfg); sep5 driver
| Metric | SEP5 Driver Performance | |----------------------------|-------------------------| | Max throughput (SPI) | 10 Mbps | | Interrupt latency | ≤ 5 µs (on 100 MHz MCU) | | DMA-assisted transfer | 0% CPU overhead @ 1 Mbps| | Context switch to ISR | < 2 µs | // Initialize SEP5 at address 0x50 on I2C
// Start streaming data sep5_start(dev); .sampling_rate = 1000
// Read data (blocking) uint8_t data[64]; int len = sep5_read(dev, data, sizeof(data), 100); // timeout 100ms
