dsPIC33EP256MU806 - Using the Watch Dog Timer (arigead)
There's only one page on the WDT in the datasheet DS70616G and it seems fairly straight forward. I'm using two LEDs one on Pin D0 and another on D1 to test out the WDT. On power up if the bit RCONbits.WDTO is set I set one LED and clear the other and vice..

EZBL support for dsPIC33FJ32MC304? (twelve12pm)
Hi all, I'm a bit confused by release notes for the Easy Bootloader, here:http://ww1.microchip.com/downloads/en//softwarelibrary/microchip%20easy%20bootloader/ezbl%20release%20notes.htm The notes mention a variety of dsPIC33FJXXXMCX06/X08/X10 parts but no..

FFT on dsPIC33EP never works but in FJ yes (David Felipe)
Hello comunity!I developed a "signal analyzer" on a dsPIC33FJ128GP802 based on Microchip dsp libraries for the spectrum, then I write a code for show data in a ILI9341 display in a graphical mode and the code works very well with a maximum FFT size of 102..

dspic33fj256gp506 uart2 (abradley9xx)
So I can see all kinds of reports on this. I can send from the pic fine, as long as I send 0x00 as the FIRST char, or else the data gets all screwed up, some kind of shift but not really. I can receive fine, as long as I send 0x00 to the pic as the LAST c..

dspic33fj128mc804 brushed DC MOTOR (direct drive) algo. (thieulam)
Hi to all.I have a dc motor with brushes (100V 20A 240N / m) and a MOSFET H-bridge driven by a dspicc33fj128 PWM.
I was able to move the engine correctly and give it the maximum torque (240N / m @ 20Amp).
Now I have the problem that I have to avoid that..

dsPIC33FJ32MC304: What's going on with the datasheet / family reference manual? (twelve12pm)
The datasheet / family reference manual are very confusing. The latest example: SPI. I have what appears to be the latest revision of the dsPIC33FJ32MC304 datasheet, revision G from April 2012, 70291G. Section 18.0 of this datasheet, "SPI," gives only a t..

dsPIC33FJ32MC304: SPIxCON1.SPRE confusion (twelve12pm)
dsPIC33 FRM section 18 (DS70005185A) gives the following description of SPIxCON1.SPRE:
111 = Secondary prescale 1:1
110 = Secondary prescale 2:1
.

.
000 = Secondary prescale 8:1
So what are the unwritten prescale values? 3:1, 4:1, 5:1, 6:1, 7:1?
