I built a new AI scheduling tool Check it out here.

I built a new Serial number generator Check it out here.

I built a Modbus RTU CRC checker Check it out here.

• mcd = directional intensity (good for indicators).
• lm = total light output (good for illumination).
• lux = light on a surface.
• At 1 m, on-axis: lux ~ cd.
• A 180 mcd LED is an indicator, not a light source.
• Ring of 54 white LEDs at ~8.5 lm each -> ~459 lm total -> ~146 lux at 1 m on-axis (assuming wide spread). Usually run well below max for comfort and thermals.

1) Frame structure (RTU)

Field	Size	Notes
Address	1 byte	Slave ID: 1…247 (0 = broadcast; 248–255 reserved).
Function code	1 byte	e.g., 0x03 Read Holding Regs; 0x06 Write Single Reg.
Data	0…252 B	Depends on function: start address, quantity, payload, byte count…
CRC-16	2 bytes	Little-endian on the wire: CRC low byte first, then high byte. Polynomial 0xA001, init 0xFFFF.

Framing by silence: ≥ 3.5 character times between frames; ≤ 1.5 character times between bytes within a frame.
