Īfter the driver for CP2102 was installed, a few sample Arduino sketches such as 'Blink' and 'Fade' were uploaded to make sure the chip was still functioning before designing the board in Eagle PCB.

0.1uF capacitor x 1 between module's DTR pin and RESET (chip pin 30).

Arduino Mega 2560 PIN mapping table A diagram showing the correspondence between the pins on an Arduino board and those of the ATmega2560 microcontroller. There are pin mappings to Atmega8 and Atmega 168/328 as well.

CP2102 USB to UART TTL Module (one that has a DTR pin), with the connections: Below is the pin mapping for the Atmega2560.Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. 16MHz ceramic resonator connected between chip pins 33 and 34, with resonator's ground pin connected to chip's GND. Each of the 54 digital pins on the Arduino 2560 Mega can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions.From other online sources, it looks like timer 5 has to be fiddled with in order to get it to work.

how to get one PWM more on MEGA Hello, Having trouble understanding how to get PWM working on pins 44-46 for the Arduino Mega 2560. LED x 1 and 1k current limiting resistor x 1 connected between D/13 (chip pin 26) and GND, this is same as the Arduino Mega 'L' LED, to be us as indicator to test prototype. It looks like File->Examples->Firmata->StandardFirmata will allow PWM on any of the 70 MEGA pins.10k pull-up resistor x 1 connected between RESET (chip pin 30) and VCC/AVCC.0.1uF bypass capacitor x 3, connected in parallel to 3 of the VCC/AVCC and GND pairs (chip pins ).I need a PWM frequency of about 31kHz and need to setup the appropriate timer control register for that. I need to change the PWM frequency of the PWMs I use if needed. ATmega2560 chip from an Arduino Mega2560 clone (functional chip and bootloader) removed with a hot-air gun, soldered on to a TQFP100 breakout PCB. The PWM pins are shown but I cant find which timer controls which PWM output.

[url= I am struggling to get either of these to work - even something basic like just attaching it to an led and using m() to manually control the pwm brightness.Ĭan someone point me in the direction of an easy way to get this enabled? Even something simple like a link to some code that enables 16 bit and sends a pwm signal thats changed manually in the code?īelow is a link to the code I would like to eventually get working as 16 bit: const int flowUp = 4 // the number of the pushbutton up pinĬonst int flowDown = 3 // the number of the pushbutton down pinĬonst int flowZero = 2 // the number of the pushbutton zero pinĬonst int controlPin = 13 // the number of the flow controller pinĬonst int maxFlow = 255 //this can be any number - it's the number of steps between dimmest and brightest.A prototype board was made as proof of concept, the components, placements, and connections are: I've been trying to use Timer1 to do so as directed on these two pages: The issue is I need smaller voltage steps than the default 8bit pwm enables so I'd like to take advantage of the 16 bit counters on my Mega chip. As it is right now it works using 3 buttons: up, down, and zero.

I'm trying to use an Arduino Mega 2560 for a simple controller for a 0-5v analog signal controlling a mass flow controller. There are three pins in the right-hand (Digital) block of pins that can also be used as PWM outputs.
