6. In-Circuit Debugging

The Multiprogrammer board has an in-circuit debugging

(ICD) connection between the USB peripheral device

and the target microcontroller. This allows the Flowcode

software to start, stop, step and inspect an active

program, synchronized both in hardware and Flowcode

6 software. As well as the standard ICD operation,

Flowcode is capable of reading back real time variable

values from the target device.

To use the Microchip PICkit2 ICSP interface, remove

the power supply and the USB cable from the

Multiprogrammer. Then place the 3-way jumper link

associated with J12-14 to the left hand side of the 3 x

3 header pins, labeled ‘ICSP’. Then simply connect the

PICkit into the Multiprogrammer via header J20.

7. In-Circuit Test

The Multiprogrammer board has an in-circuit test (ICT)

connection between the USB peripheral device and all

of the target microcontroller’s I/O pins. This allows the

Flowcode 6 software to monitor all of the signals on the

board in either analogue or digital modes.

The in circuit test feature can be combined with packet

decoding to allow data and control busses to be explored

and debugged

8. Low voltage programming

Many PICmicros have a low voltage programming mode

where it is possible to program the device without the

need for a 12V supply line or charge pump. The difficulty

here is that different families of PICmicro devices use

different pins as the Low Voltage programming pin. B3 is

predominantly used for this function but B4 and B5 are

also used on some devices. For this reason the version

9 EB006 does not support low voltage programming

modes so care must be taken when generating the chip

configuration to disable the low voltage programming

functionality. If the low voltage programming

configuration is left enabled then you will not be able to

use the LVP pin as an I/O pin in your application.

Protective cover

Most of the boards in the E-blocks range can be fitted

with a plastic cover as an optional extra. These covers

are there to protect your E-blocks board therefore

extending the life of the board. The covers also prevent

the removal of external components while still allowing

for the adjustment of applicable parts on the board.

12mm M3 spacers, anti-slip M3 nuts and 25mm M3 bolts

can be used to attached the cover to the board. These

are not included but can be bought separately from our

website.

The order code for the EB006 PICmicro® MCU

microcontroller cover is EB706.
