May I take a look at your code? I have more than 30 years of experience in programming and electronics. Arduino-based boards are my main development environement since 2010. Please feel free to contact me in chat here.

hi there i can help you with that. i am very familiar with the RS232 protocol and also the ATmega256 so i think i can debug your code.

Hi, I am an embedded system developer. I have good experience of working with Arduino Mega2560 variant. I think I can review the code and help you get it working. Please share the Arduino script or similar which is not working as expected. Let me see which pins are configured where and what routines are written to be executing or not executing. If you have any questions for me please ask. I have gone through few such situations with Atmega series regarding the Interrupts, so I might be able to give you some solutions. Thank you.

I have good understanding of interrupts for arduino mega. Please send me the code file for correction along with the pins used.

// Interrupt service routine for pin change PCINT0 // This routine is called any time the input on PCINT0 changes state (H to L or L to H) ISR(PCINT0_vect) { PWM_in = digitalRead(INPUT_PIN); if PWM_in == HIGH) { bitSet (Button_flags, 0); // Set a flag to indicate that the signal changed from HIGH to LOW PCMSK0 |= 0b00000000; // Disable futher interrupts from PB0/PCINT0 // Processor clears the interrupt flags } } Regards, Jim

As a full-stack engineer with experience in microcontroller programming, I am confident that I can provide an effective technical approach to your project. My expertise lies in programming, debugging and optimizing C++ code for microcontrollers such as the ATmega2560. I have a thorough understanding of the process of compiling and uploading code to a microcontroller and am familiar with the interrupt handling capabilities of the ATmega2560. My approach to the project would involve a thorough review of the code, ensuring that the pins defined for the switches are compatible with interrupts on the ATmega2560. I would then debug and optimize the code to ensure that the interrupts are configured and handled correctly. If necessary, I would provide recommendations on any additional changes to the code that are necessary to ensure that the project is completed in an effective manner.

Dear Sir, I would like to present myself as prospective candidate to do your project. I have sound knowledge and experiences in Electronic and Programming , including Micro Controller such as Arduino (ATmel) and Microchip programming. I have read your project description and I would be the best candidate to do your project. What is the compiler and IDE you used for programming ? Can you share the code via chat, so could examine it in advance. There are many reasons a Interrupts not to work. There are internal misconfiguration and external hardware factors such as, not providing proper voltage levels, contribute to not working of interrupt. Please message me if you like to have further information. And also regarding fee, I wanted to put some ting like AUD25. but system didn't let me. I promised to do provide you the service to your satisfaction with minimum time. Expecting a favorable reply, I remain. Isuru Athukorala

Hello! I understand that you require an experienced PLC expert for your project involving the Arduino's ATmega2560 microcontroller. I have used the development platform of choice for that task in the past, and I am a great choice to do code reviews because much of my experience relates to correcting other's work. I have several questions about the hardware platform that you have developed, because nothing beats the real thing in testing. Please contact me immediately so that we may finalize a proposal and begin work immediately. Thank you! Best Regards, Henry
