  1. Hi Jon. I have tried some simple I2C programs before on the same board, and I just made sure the core is updated, abaout the verbose, I don't think the problem would be there, considering the program starts running but freezes when it's about to write the first answer.
  2. Hi Jon. I'm using the Chipkit core, I'm not really sure if it's updated, I think it is anyway. I made a mistake earlier, I'm not using the MAX30100 debug program but the one attached to this message. The other file contains the text from the message box. MAX30100.docx MAX30100_Minimal.ino
  3. Hi Jon, thanks for answering. I'm currently using Arduino IDE 1.6.9 I talked with a teacher and he says it's a software problem, he came to that because the program worked on Arduino UNO but didn't on ChipKit, also, I used an external pull-up instead of the one provided by the jumpers. The teacher says it might be a stack overflow problem, could that be it?
  4. I'm having problems printing data on-screen, when the program is about to write it, the board freezes, it won't even allow me to reset. In the module of the MAX30100, Vin is connected to 3,3v, GND to GND, SCL to RB8, SDA to RB9, there are also 4k7 resistances conected between SDA and 3,3v, the same goes for SCL and 3,3v. INT remains unplugged. The almost fully white screen is the result of using the ChipKit board. The image filled with data shows the results obtained with an Arduino UNO board, wich were proved right with a saturometer. The last image shows the module for the MAC30100. The files are the libraries used and the program. I tried changing the communication speed from 100kHz to 400kHz but there wasn't any changes. I also tried it with a pull-up resistence on the INT port of the MAX30100. examples.7z MAX30100.7z
