    Analogshield and ChipKIT Wi-FIRE

    Thank you Marshall! Currently I already made my application to run using Chipkit UNO32 and MAX32 (together with AnalogShield). My next step is to test in a Arduino DUE (I already got one). My application is in scientific research, so I need as much speed as I can get (to increase time resolution). Thus very soon I will buy the Wi-FIRE to test it. Do you have any suggestion to speed up the SPI transmission (ChipKit to AnalogShield)? In my application, once I reach 500 Hz wave, or above, I start to see time quantization, probable due the SPI speed. I realize that the AnalogShield do not use the buffered DSPI. Any clue? This is the piece of my current code, which is inside a loop: time=micros()-time0; mag_out = -1 + MED_VALUE*(1+sin(pi2_mil* time)); #ifdef ANALOG_SHIELD analog.write(0,MAG_value_out); #endif Thank you, Adriano

    Analogshield and ChipKIT Wi-FIRE

    Does anyone know if AnalogShield will work on the new ChipKit Wi-FIRE (with few modifications) ? I look inside the library and I saw several " #ifdef __PIC32MX__ " However the new ChipKit WI-FIRE is " PIC32MZ ", MZ not MX. In other words, without any modification it will not work. However, if the chip is similar, as described in this forum, should be easy. Thanks
