Very sorry for the excessive delay in getting back to you – this blog gets a lot of spam and somehow you got lost in the deluge!

Did you get the PIC working as you wanted in the end? I do have the code banging about somewhere if you still need it.

I used to use the dspic30f6015, following peter harrisons micromouse. I had many problems with the chip but mostly due to certain hardware problems. To simplify the circuit as much as possible, I decided to migrate to a dspic33f. It seems much easier to use and also faster. However, I tried setting up the ADC module on the dsPIC33FJ128MC802 but I am unable to do so. I see that you have much experience with the dspic33f and pretty much very familiar with the peripherals. As such, I was wondering if you could explain to me how to set up the ADC module on the dspic33f. What I basically need from the module is : 1) Basic conversions 2) No interrupts 3) Basically as simple as possible with the best conversion rate. My setup is pretty simple as I just breadboarded it. I have the dsPIC33FJ128MC802, 20mhz crystal, 3.3v supply and some basic circuitry for the chip and a tsl262r sensor. I connected the output to an2 of the dspic. Of course, I have read the datasheets many many times but this seems to be very different from the dspic30f's where i could get it running very easily. I hope that you can help me. Thank you, Patrick Hi there,

But luck would have it I was playing with i2c yesterday, although that code is fairly hacked and not presentable. I would suggest you look at http://www.microchip.com/forums/tm.aspx?m=66491&mpage=1&key=i2c%2cperipheral%2clibrary&#68717 Two things to note - first is that this is for a dspic (or pic24) but should port over to the pic32 without too much trouble (function names will change, but look at the peripheral lib documentation for clues). Secondly this does not use interrupts, there is an app note from microchip (CE119) about using i2c with eeprom - it uses interrupts, but not directly. Hope that helps.

I'm struggling to get this working so did a search on the web trying to find someone who has done this. Your description of the Micromouse and Quadrature Decoders indicates that you are using the PIC32 with I2C EEPROM. Would you be willing to share a code snippet with me showing how you got the I2C EEPROM working with the PIC32? I would greatly appreciate it. Thanks.

Drivers are great....but they require additional MOSFET driver ICs....dont they? I am waiting for it…!
