DSPIC33CK32MP102 ADc sampling time

Greetings The screenshot below is from the "12-Bit High-Speed, Multiple SARs A/D Converter (ADC)" document. Knowing the values of Rss, Ric and Chold is important in being able to calculate minimum sampling time. I am planning to use DSPIC33CK32MP102-E/2N from dsPIC33CK64MP105 FAMILY of microcontroll..

DSPIC33EP512MU810, Help adding HID USB Functionality

I am using DSPIC33EP512MU810 for the first time and am having trouble setting it for Device USB HID Operation. The mcc only supports CDC and Vendor for this device. Microchip's HID documentation is from 2008, and 2015, and does not describe how to setup HID in latest MLA (which has HID files from 20..

PWM1 and PWM2 Does not working correctly!

IC:dsPIC33EP128MC506 at First Stage(case "OutPul_Mode_PUL_NEG"),the code set PWM module working as "Redundant output mode" and set the "OVRDAT<1> provides data for output on PWMxH pin" and "OVRDAT<0> provides data for output on PWMxL pin" to close the PWM output , at this state ,if use this code ..

DSPIC33CK32MP102 ADC input

Greetings I am planning to use DSPIC33CK32MP102 for an application that needs time-critical conversion of single ended analog inputs of SAR ADC. For this I am planning to use dedicated core as shown in the image below. For 28-pin UQFN package, ANN0 and ANN1 are not available (see the complete pin fu..

dsPIC33CK256MP508 start ADC in assembly

How can you start the ADC in assembly? I use an .s file for the assembly code that works fine in itself.In for instance PIC18 assembly one can use: "bsf ADCON0, GO, ACCESS"But if I try this with let's say: "bset ADCON3L, CNVRTCH" for the dsPIC33, I get an "Invalid operands specified ('bset.b ADCON3L..

Should I update to MPLAB 5.45 for dsPIC development

I'm using 5.10 currently and officially it doesn't appear to support the version of MCC I'm using (3.95) though it has worked so far. Not sure which XC16 as I'm not on the right computer to check right now. Trying to switch to a newer MPLAB gave me what looked like a junk folder, something like ".ge..

Understanding core-to-core communication in the dsPIC33CH series

Is there any good example code out there? I'm trying to work with the MCC-generated libraries but right now it feels more like obfuscation than an API. In the interests of keeping things simple I'm working with polling not actual CPU interrupts. Oddly enough interrupts may prove to be a red herring,..

dsPIC33CH CAN FD module won't exit configuration mode

Hi all, I'm developing on a dsPIC33CH128MP505, and am having trouble working with the CAN FD module. I am somewhat confident that I have configured the clock stuff correctly, after which I activate the can clock generator, the module, and enter configuration mode successfully. However, after setting..

dsPIC33CH configure MOSI on RD8?

I'm actually trying to configure the second "Click" interface of a "Curiosity" board, but I can't seem to get SPI out onto the right pin. RD8 appears to be outside the range for remapping the pin using PPS, although according to the datasheet it appears to be a designated SPI pin:"SDO2/PCI19/S1SDO1/..

PWM problem with the dspic33fj32GP104

Hi, I have a problem with the dspic33fj32GP104 microcontroller, I can't find the way to generate PWM signals, because there are no specific control registers. Even so on the official website of microchip says it has 3 pairs of PWM. Thanks for your help...
