Re: Odd mills behavior

That code won't compile, so it isn't what you were running.

Re: SparkFun Pro Micro and SERIAL1 (USART serial)

Any ideas? Post ALL the code, using code tags, so we can see what you have done wrong. Use of Strings is a bad idea with Arduino, as they cause memory problems and program crashes. See forum.arduino.cc/index.php?topic=382944.msg2640860#msg2640860 Use C-strings (zero terminated character arrays) ins...

Re: smallest, cheapest way to send wireless signal

do this over a fair distance
Please define "fair distance", in meters or kilometers, and describe the environment, i.e. whether this distance is line of sight (no hills, walls, buildings, trees in between transmitter and receiver).

How will you receive the signal?

Re: How do you program something like this?

How would I actually burn the program to the chip? All instructions, example code, software and the necessary interface would be included in the SDK and development board package. Consult the associated Quick Start guide. If you have ever used Arduino, program development and upload is basically th...

For the Ehong module you will need the: EH-MEVK-MC10-002 is the development evaluation board, providing the complete interface features of EH-MC10. The Quick Start Guide guides you to launch and run the modules within minutes to test and evaluate the modules' performance. You will also need the SDK ...

Re: How do you program something like this?

To program any micro, you must have the appropriate programming interface. You also need the original source code for a particular module, so you don't have to recreate all of it to have the original functionality, as well as the appropriate IDE. Since you won't ever get the source for the module yo...

Re: How do you program something like this?

Why would you want to program the board?

Microprocessors found on boards like that are often programmable only one time (OTP).

Re: UART to UART communication

A series resistor is not needed unless one of the units may be powered down independently of the other (which is not a good idea in any case). If the above is the case, you need the resistor to protect the powered up output from overcurrent, and to protect the powered down device from "phantom power...

Re: Have I broken my weather shield?

If circuits under power get wet, electrolysis and corrosion usually cause irreversible damage. Your only repair option is to take everything apart, clean the PCBs and components as well as you can (washing PCBs in distilled water is fine, but is not OK for some sensors), dry everything extremely wel...
