Please forgive what I'm sure will be a stupid question. I'm an Arduino newbie working on my first project. I have some VB6 programming experience but no C+ experience at all so the syntax and formatting throws me off.
I'm trying to merge the BME280test and the NRFLITE Dynamic TX library examples to make a temp sensor I can put outside to radio the info inside.
I merged the code in what made the best sense to me but when I try to upload it to the Mega i get a message that reads " 'printValues' was not declared in this scope" and I don't know why.
(I also want to add Photoresistors for Sun Tracking - that is addressed after the problem code. That code works and I can merge it with the BME280 code so if I can merge the BME280 and MRFLITE codes I'll be able to merge that code without problem)
Someone please enlighten my to my ignorance. Code follows:
/*
Demonstrates sending data packets of different length. The receiver will check to see what size of
packet was received and act accordingly.
Radio Arduino
CE -> 9
CSN -> 10 (Hardware SPI SS)
MOSI -> 11 (Hardware SPI MOSI)
MISO -> 12 (Hardware SPI MISO)
SCK -> 13 (Hardware SPI SCK)
IRQ -> No connection
VCC -> No more than 3.6 volts
GND -> GND

this is the Photoresistor set code that I will want to merge with the code above. I can merge it with the BME280 code (below) and it works so if I can merge the BME280 and radio code (above) if I can get them to work
/***************************************************************************
This is a library for the BME280 humidity, temperature & pressure sensor
Designed specifically to work with the Adafruit BME280 Breakout
----> http://www.adafruit.com/products/2650
These sensors use I2C or SPI to communicate, 2 or 4 pins are required
to interface. The device's I2C address is either 0x76 or 0x77.
