mikoBasic PRO for dsPIC30/33 and PIC24
MikroElektronika
Breakpoints are divided into two groups: hardware and software breakpoints. The hardware breakpoints are placed
in the MCU and provide fastest debugging. Number of hardware breakpoints is limited (4 for PIC24 and dsPIC33
family, for dsPIC30 family this number depends on the MCU used). If all hardware brekpoints are used, then the next
breakpoint will be software breakpoint. These breakpoints are placed inside the mikroICD and simulate hardware
breakpoints. Software breakpoints are much slower than hardware breakpoints. These differences between hardware
and software breakpoints are not visible in the mikroICD software but their different timings are quite notable.That’s why
it is important to know that there are two types of breakpoints.
The picture below demonstrates step-by-step execution of the code used in above mentioned examples.
Common Errors:
- Trying to program the MCU while the mikroICD is active.
- Trying to debug Release build version of the program with the mikroICD debugger.
- Trying to debug program code which has been changed, but has not been compiled and programmed into the MCU.
- Trying to select line that is empty for Run to cursor [F4] and Toggle Breakpoints [F5] functions.
- Trying to debug MCU with mikroICD while Watch Dog Timer is enabled.
- Trying to debug MCU with mikroICD while Power Up Timer is enabled.
- Trying to Step Into [F7] the mikroBasic PRO for dsPIC30/33 and PIC24 Library routines. Use Step Over [F8]
command for these routines.
- It is not possible to force Code Protect while trying to debug MCU with mikroICD.
- Trying to debug MCU with mikroICD with pull-up resistors set to ON on RB6 and RB7.
