in-circuit serial programming
Install the programming software according to the instructions included with your programmer.
Connect your programmer to the LAB-X board using a 10-pin ribbon cable (part# 10CAB). Do not twist or fold
the cable to make the connection. The connectors on the programmer and LAB-X boards should line up to
allow a straight connection.
If your LAB-X board has a ZIF socket, raise the lever. Insert the microcontroller into the socket on the LAB-X
board and lower the lever to lock it into place. Make sure that the notch on the end of the microcontroller is
aligned with the lever end of the socket.
If your LAB-X board does not have a ZIF socket, carefully line up the PICmicro microcontroller's pins with the
holes in the socket and press it into place. Make sure the notch on the end of the microcontroller is aligned
with the notch at the end of the socket.
Connect a 16VDC adapter (part# ACAD) to the programmer's power jack. You may have different adapters for
the programmer and LAB-X board. Make sure you power the programmer with the 16V adapter.
Connect a 12VDC adapter (part# ACADX) to the LAB-X power jack. You must connect power to the LAB-X
board in order to program the microcontroller.
Run the programmer software on your computer and use the programming procedure to program the part.*
*The LED indicator on the EPIC will remain lit at half intensity when the EPIC is connected to the LAB-X board.
The indicator should light fully when a programming operation is in progress.
Migration from 16F877A to 16F887
The PIC16F877A is an older part that is becoming obsolete. In our bundled development
systems, we have replaced the 16F877A with the more modern 16F887. However, many
of the books that we sell only have sample programs for the 16F877A. This is especially
problematic in the book "LAB-X1 Tutorial and Resource Book" by Harprit Sandhu,
which is included in our Super Bundle development system. The following information
is intended to assist in converting programs for use with the 16F887. The syntax below is
for PICBASIC PRO Compiler.
Much of the function of the 16F877A ADCON1 register has been moved to the
ANSEL and ANSELH registers in the 16F887:
ADCON1 (16F877A)
ANSEL (16F887)
ANSELH (16F887)
ADCON1 = %00000000 '($00, 0)
ANSEL = %00011111
ANSELH = %00000000

DEFINE ADC_CLOCK does not function on the 16F887. This define must be
replaced by a setting to the ADCON0 register:
DEFINE for16F877A
ADCON0 setting for 16F887
DEFINE ADC_CLOCK 0
ADCON0 = %00000000
DEFINE ADC_CLOCK 1
ADCON0 = %01000000
DEFINE ADC_CLOCK 2
ADCON0 = %10000000
DEFINE ADC_CLOCK 3
ADCON0 = %11000000
