Detailed Description

Heap-free console formatting for camera livestream diagnostics.

Implements bounded string, integer, and IPv4 output through the EK-RA8D2 UART console without allocating temporary storage.

Tag

[Ring 6 / APP] {World: S}

Provides bounded decimal, IPv4, and string formatting directly to SCI8 using fixed-size stack buffers and no heap allocation.

Enumeration Type Documentation

c6_cam_console_t

enum c6_cam_console_t : uint32_t

Bounded formatting sizes and IPv4 extraction constants.

Enumerator
k_c6_cam_console_text_max	Bounded console string length.
k_c6_cam_decimal_digits	Digits in a 32-bit decimal rendering.
k_c6_cam_ipv4_high_shift	Shift of the first IPv4 octet.
k_c6_cam_ipv4_octet_mask	Mask selecting one IPv4 octet.

Function Documentation

c6_cam_put_ip()

void c6_cam_put_ip

(

uint32_t

ip

)

Write one IPv4 address to SCI8.

Formats the network-order address as four dotted decimal octets.

Parameters

[in]

ip

IPv4 address in the representation used by the C6/NetX path.

Precondition

The board console is initialized.

The address value came from a C6 or NetX network structure.

Postcondition

Four decimal octets and three separators are queued.

The address value remains unchanged.

Note

This helper emits no trailing whitespace or newline.

c6_cam_put_u32()

void c6_cam_put_u32

(

uint32_t

value

)

Write one unsigned decimal value to SCI8.

Formats the value into fixed stack storage without libc allocation.

Parameters

[in]

value

Value to emit.

Precondition

The board console is initialized.

Fixed helper stack storage is available.

Postcondition

The decimal representation is queued for transmission.

No application state except console output is modified.

Note

The full uint32_t range is supported.

c6_cam_puts()

void c6_cam_puts

(

const char *

text

)

Write a bounded NUL-terminated string to SCI8.

Measures at most the helper's fixed string bound before one board-console write.

Parameters

[in]

text

NUL-terminated text to emit.

Precondition

text is nonnull and terminated within the fixed bound.

The board console is initialized.

Postcondition

The bounded text bytes are queued for transmission.

Caller-owned text remains unchanged.

Note

Console write failures are intentionally ignored by this diagnostic helper.
