PCPWM2: Setting the operating percentage of the two separate PWM output(s) and the selection of the operating frequency and from the PC
The offer code shows easy way to control of 2x pwm outputs from PC screen.
For Arduino boards: NANO - UNO - MEGA
Arduino pins are used: see connections (for Mega: D9/D10)
 
Electrical and practical notes: (Recommendation:Use the following accessories for testing as well as for later use: Lnk1 - Lnk2 )
It can be powered only from PC USB but it is recommended to use an external voltage source 9V/1A (on dc plug or on VIN pin).
On outputs can connect some other type of 5V Loads up to 20 mA (for each output) like LED, PWM drivers (Link1 - Link2 -
When finishing uploading code, be sure to do a Default Reset (see below)
 
User guide and explanations:
Select the PWM frequency depending on the load(s) used.
PWM Out1: According to user settings - PWM Out2: According to user settings
The Selected PWM frequency is the same for both PWM outputs!
The set values remain stored (EEPROM) even after a power failure!
The code in the board does independently from PC according to the last settings values!
 
Download the HEX codes below, unpack and upload to the proper Arduino board (Use a free net tool for example XLoader)
1. uc ATmega328-16MHz (MINI,NANO,UNO..): PCPWM2try-m328 - Time-Limited trial version (12 hours) then need restart!
2. uc AtMega2560 (Mega(ATMEGA2560)......): PCPWM2try-M2560 - Time-Limited trial version (12 hours) then need restart!
 
Description of HexCode commands ( You can test the uploaded code using some free serial communication software such as Termite (select: Append CR)):
AT command (ASCII characters + ENTER) - Baud 9600,8 Data bits, None Parity,1 Stop Bit
AT - attention command (returns OK)
I? - software code info (return ucAppName)
DRESET - Default Reset ( SV01=4 SV11/SV21=0) - BE SURE TO DO THIS AFTER UPDATING THE CODE!
PV0X? = Return PV0X= set percentageX X=1-2 (0-100)
SV01? - Return value of SV01 = selected pwm frequency (see Legend)
SV11? - Return value of SV11 = working percentage of pwm Out1
SV21? - Return value of SV21 = working percentage of pwm Out2
Set-Preset commands: Some or all commands use internal uC EEPROM for memorization when power loss!
SV11=X - X=Set (working) pwm Out1 percentage (0-100% 0=0V 100%=5V)
SV21=X - X=Set (working) pwm Out2 percentage (0-100% 0=0V 100%=5V)
SV01=X - X=pwm frequency (selection 1-7)

PC Application(s) for offered Hex code (for WINDOWS):
In order for the offered PC applications to work, it is necessary to download and install (one time only) VB6RunTimePlus2.2
Download the PC application, unpack, and start (allow windows to start applications - see HOW) enter the COM port number where the Arduino is connected and test it...
