NAME

TempPressureNTCWiFi firmware

Prerequisites

• Arduino IDE 1.8.19
• ESP32 in Arduino IDE
• OTA Drive

Feature

• Read 4 channels external thermistor 100k B25/50 = 3950.
• Read 2 channels 4-20mA.
• Transfer data through ESPNOW or UART1(High-Priority).
• MAC Address destination setable for ESP NOW.

Usage

1. Set MAC Address Destination Send ESPNOW package data following frame:

MACS:<MAC Destination>
	with <MAC Destination>: 6 bytes of destination mac address

example: Destination Mac Address 12:34:56:78:90:AB
	Frame need to send:
		MACS:[0x12][0x34][0x56][0x78][0x90][0xAB]

2. ESPNOW package respone

	04NTCPS: <NTC1> <NTC2> <NTC3> <NTC4> <I1> <I2> <CRC>
		04NTCPS: Header
		<NTC1-4>: 8bytes float value NTC1 temperature in *C, ASCII format
		<I1-2>: 8bytes float value curent of channel 4-20ma, ASCII format
		<CRC>: 5Bytes CRC 16 Modbus value 00000-65535, ASCII format
Example: 
	04NTCPS: 0023.456 0065.432 0-45.678 0567.890 04.00000 20.00000 34567
		NTC1 = 23.456*C
		NTC2 = 65.432*C
		NTC3 = -45.678*C
		NTC4 = 567.89*C
		I1 = 4.0 mA
		I2 = 20.0 mA
		CRC = 34567 

3. UART Transceiver Package need to send (ASCII mode)

	> R <Register> 00000000<CR><LF>

Data respone

	> R <Register> <Value> <CRC><CR><LF>
		with <Value> : 8bytes data
		<CRC>: 5Bytes CRC 16 CCIT value 00000-65535, ASCII format

Registers table:

Registers	Description

T2	Temperature channel 2 for old version (NTC2)
T3	Temperature channel 3 for old version (TC_K 4-20mA)
T4	Temperature channel 4
I1	Currrent 4-20mA channel 1
I2	Currrent 4-20mA channel 2
N1	NTC Temperature channel 1
N2	NTC Temperature channel 2
N3	NTC Temperature channel 3
N4	NTC Temperature channel 4

		> R T2 -234.567 01234<CR><LF>
		> R T3 0999.999	65535<CR><LF>
		> R T4 0253.452 02345<CR><LF>
		> R I1 04.00000 45678<CR><LF>
		> R I2 20.00000 65530<CR><LF>
		> R N1 00000000	00001<CR><LF>
		> R N2 00000000 21453<CR><LF>
