Target Board
The blockset supports any board equipped with a compatible dsPIC DSC, PIC32 or SAM microcontroller.
Ready-to-use Simulink templates with preconfigured peripherals are provided for the following development boards:
| Development Board | PIM or DIM - DSC MODULES | Development Board | PIM or DIM - DSC MODULES |
|---|---|---|---|
 | • Integrated dsPIC33CK256MP508 DSC |  | • EV14E50A
- dsPIC33CDV64MC106 • EV04R09A - dsPIC33CDVL64MC106 |
 | • dsPIC33AK128MC106 DIM EV68M17A
(Internal/External OpAmp) • dsPIC33CK256MP508 DIM EV62P66A (Internal/External OpAmp) • dsPIC33CK64MC105 DIM EV03J37A (Internal/External OpAmp) |  | • dsPIC33CK256MP508 PIM MA330041-2
(Internal) / MA330041-1
(External) • dsPIC33CK64MC105 PIM MA330051-2 (Internal) / MA330051-1 (External) • dsPIC33EP256MC506 PIM MA330031 (External OpAmp) |
 | • Reference design - Potentiometer on Throttle, buttons and encoder on AUX board |  | • dsPIC33AK128MC106 General Purpose DIM EV02G02A (External Mode ready) |
 | • Integrated dsPIC33AK512MPS506 DSC • Power supply and digital power management applications • On-board debugger with USB-UART bridge (no external programmer required) |
Programmer/Debugger
Required for boards without integrated programmers. Supported programmers: ICD4, ICD5, PICkit4, PICkit5, PKOB4, Snap
J32 programmer (Segger) supports SAM microcontrollers only.
UART to USB Bridge Cable (Recommended)
Recommended for boards that lack USB-to-UART bridge or when higher bandwidth (>460 kbaud) is required.
High-bandwidth communication (External Mode, 12 Mbaud) requires FTDI cables (All FTDI Cables):
- C232HD-DDHSP-0 (3.3V)
- C232HD-EDHSP-0 (5V)
Installation
Blockset Installation
In MATLAB Add-On Explorer, search for “MPLAB” and click Add.
Offline installation or older MATLAB releases:
- Download the .mltbx installer package from GitHub Releases page and run it from MATLAB
Custom installation location:
- Download the .mltbx package and install.p script from GitHub Releases page and place them in the same folder
- Run install.p - at prompt “Install as an add-on using MathWorks predefined folder? Y/N [Y]”, select N and enter your custom path
Check Blockset Installation
Type picInfo in the MATLAB Command Window and follow the verification link.
picInfo(‘check’) command prompt output with 3 programmers attached:
