$30-250 AUD

Paid on delivery

Need someone to create code needed for an Atmel microcontroller to read 8 inputs off a PCA9534 port expander when interrupt is triggered. Fully commented code is needed so I can learn from it also. Will only be making one milestone payment at the end of the project as it is only a very small project. Please contact me if any more details are needed.

Hi, I have exp in AVR Uc with avr studio compiler. I would be able to accomplish your task. Check my profile for my experience in embedded system. I can prove the working in proteus simulation as a draft version, if you would like to do so. Looking forward to hear from you.

What Atmell MCU you use? I can code this in C and I have some Atmega chips. PCA9534 is unavailable for me, but I can emulate it with some another chip (another Atmega)

Dear Pintek, Please specify the microcontroller model first and then let me know do you want the code for academia or some RnD? Because I have to choose appropriate compiler. Do you also want simulations? P.S. You may check my profile, I am good at microcontrollers. Regards

What AVR chip you are using? also if you are using WinAVR or any other compiler,are all the I2C ports using same protocols and SCL frequencies? As you know I2c protocols vary very very slightly for some devices

Hi, I have a long experience in product design with Hardware and Software. I am also experience with Arduino (Atmel micrcontrollers) and based on that I wish to Bid this project. I am assuming here that the interrupt you mentioned is the interrupt from PCA9534... Will you be using the I2C pins of the Atmel microcontroller for interfacing to PCA9534? I saw your mention about milestone payments at the end of project.. We can discuss on that too... Please let me know.. Vinod
