Htv 3.7.1 Register -

uint8_t reg_val = i2c_read_byte(DEV_ADDR, REG_HTV_CTRL);

Version 3.7.1 is a patch release that addresses critical "race conditions" found in the 3.7.0 major release. Users upgrading to 3.7.1 will notice the following specific changes to the Register functionality:

In the context of the HTV architecture, the "Register" is not merely a log; it is the System of Record (SoR). It maintains the current state of all tracked entities (whether they be vehicle telemetry units, financial transactions, or IoT node states). Htv 3.7.1 Register

Key Functionality:

A concise guide to the Register component/API in HTV (version 3.7.1): purpose, common usage patterns, key methods/properties, examples, and troubleshooting. uint8_t reg_val = i2c_read_byte(DEV_ADDR, REG_HTV_CTRL);

Requirement: Minimize output voltage ripple (<10mV).
Solution: Force MODE_SEL = 0 (PWM) permanently. Version 3

// In initialization
reg_val = i2c_read_byte(DEV_ADDR, REG_HTV_CTRL);
reg_val &= ~0x02;   // Clear bit 1
i2c_write_byte(DEV_ADDR, REG_HTV_CTRL, reg_val);
