Detailed Description

UART communication configuration structure.

Configuration parameters for UART mode operation (only used when SPI_MODE=0). These parameters configure the device's node address and timing for multi-device UART chains.

Note

These settings are only used in UART mode. For SPI mode, they are ignored.

In UART daisy-chain mode, each device must have a unique node address.

Constructor & Destructor Documentation

UartConfig()

tmc51x0::UartConfig::UartConfig ( )

default

Default constructor.

Initializes with safe defaults:

• Node address: 0 (first device or single device)
• Send delay: 0 (no delay)

Member Data Documentation

node_address

uint8_t tmc51x0::UartConfig::node_address {0}

UART node address.

7-bit UART node address for multi-device UART chains (0-127). Same value as node address in NODECONF register.

Range: 0-127 (7-bit address) Default: 0 (first device in chain, or single device)

Note

Only used when communication mode is UART (SPI_MODE=0).

For SPI mode, this value is ignored.

This is automatically configured during Initialize() if set.

In UART daisy-chain mode, each device must have a unique address. UART node address (0-127, default: 0)

send_delay

uint8_t tmc51x0::UartConfig::send_delay {0}

UART send delay.

Number of bit times to wait before replying to a register read in UART mode. Used to ensure proper timing in multi-device UART chains.

Range: 0-15 bit times Default: 0 (no delay)

Note

Only used when communication mode is UART (SPI_MODE=0).

For SPI mode, this value is ignored.

This is automatically configured during Initialize() if node_address is set.

Higher values provide more margin for timing but increase response latency. UART send delay in bit times (0-15, default: 0)
