  1. Greetings, I would like to replace the default PIC32MX250F128B microcontroller with a PIC32MX130F064B part on the Digilent ChipKit DP32 board and use an Arduino bootloader. I tried burning chipKIT-DP32-v01000303.hex by retargeting PIC32MX130F064B, but this did not work. I am assuming now that I need to make a few tweaks to the bootloader source files and recompile bootloader using MPLAB X. Has anyone done this before? What do I need to do? Thanks, Joel
  2. 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 th
  3. Hi, my question is: Is it possible to save energy on a DP32 board? is there any sleep mode using arduino environment? thanks for the answers!
  4. I'm using Arduino 1.6.9 with ChipKIT core and a DP32 rev B. My code sets up an interrupt for timer 3. When I set the prescaler to 1:32 or less, the interrupt runs just fine (although with some quirky behavior that I'll explain below). However, when I set the prescaler to 1:64 or 1:256, the interrupt appears to fail. My code is included below but I'll provide a brief explanation of its function here. The ISR increments a count variable, and sets a flag variable to high. The loop checks to see if the flag is high. If it is, it toggles LEDs 1, 2 and 3 to represent bits 5, 6, and 7 (resp
  5. The chipKIT Uno32 boards based on the PIC32MX320F128 has two link scripts: chipKIT-application-32MX250F128.ld for upload through USB, and chipKIT-application-32MX320F128-nobootloader.ld for use with chipKIT PGM. Where to find or how to develop the same nobootloader.ld for more recent chipKIT boards, including Wi-FIRE PIC32MZ2048ECG uC32 PIC32MX340F512H DP32 PIC32MX250F128B Thanks!
  6. Could we upgrade DP32 to accommodate this?
