hi,this is first time i use arduino.
i use Grove Serial Camera Kit and mega2560 and Ethernet W5100 SD shield,
i copy this code:Grove_Serial_Camera_Kit/SerialCameral_DemoCode_CJ_OV528_SoftSer.ino at master · Seeed-Studio/Grove_Serial_Camera_Kit · GitHub
circuit:
GND---GND
RX---D3
TX---D2
5V---5V
unfortunately,it always stay at "initializing camera............................."
i search a lot ,somebody say problem maybe is Serial Communication,RS232 and TTL.
i also try max232,but that also useless.
You really should read the documentation for the SoftwareSerial library. A big fat clue by four will smack you.
You really ought to think about why you are using SoftwareSerial when you have 3 unused hardware serial ports.
Thanks for your help,
but i still understand,
Do you mean the limitations
On Arduino or Genuino 101 the current maximum RX speed is 57600bps?
i change bps but it still useless,
SoftwareSerial softSerial(14, 15);<--i use mega2560,so i change RX TX pins.
#define CAM_ADDR 0
unsigned long picTotalLen = 0; // picture length
should i change?
i search a lot,but i still understand what problem.
SoftwareSerial softSerial(14, 15);<--i use mega2560,so i change RX TX pins.
The point is, why use SoftSerial at all when you have 4 hardware serial ports available ?
Even more pointed, why are you trying to use pins that belong to one of the hardware serial ports with the SoftSerial library ?
can you send full programe for UNO?
thanojan:
can you send full programe for UNO?
A full program to do what? How much are you willing to pay?

oh,i think it must connect RX TX on arduino.
Do you mean when i use softserial library,i can ignore RX TX on arduino?
but i look softserial library,it seems having some limitations.
sorry i don't understand softserial library.
thanks
Do you mean when i use softserial library,i can ignore RX TX on arduino?
I am saying don't use SoftwareSerial at all. The Mega has 4 hardware serial ports so use one of them instead.

thank you!!
i try each serial,
but it still can't initialize
i try each serial,
Please post the code you tried and details of the pins used. Did you remember to use Serial1.begin() etc when you tried ?

sorry,i don't completely understand this code.
i just revise a little.
thank you!!
When you used the code you posted which pins was the camera connected to and are you sure that you connected Arduino Tx to camera Rx and Arduino Rx to camera Tx ?
You have still not said which Arduino pins you used when using Serial1 and whether you are sure that the Rx/Tx pairs were connected correctly.
oh,sorry.
TX-TTL conect pin 18,RX-TTL conect pin 19,
thank you.
TX-TTL conect pin 18,RX-TTL conect pin 19,
The way that I read that you have TTL Tx connected to Arduino pin 18 (Serial1 Tx) and TTL Rx connected to Arduino pin 19 (Serial1 Rx)
If that is what you have done then you have the connections the wrong way round. Tx on one device should go to Rx on the other and vice versa

it can run,but didn't save image into SD card.
Is it work with Arduino Uno?
