Evaluation Kit for CMX868
EV8680
A new function from the above table can be selected whenever the >ok prompt appears in the bottom
window.
Notes:
a) Programming files must be in the Intel hex format (.HEX) in order to be usable by this programming
software.
b) The PIC µC supplied has a Configuration Word which is preset 3FB1H. This selects the crystal
oscillator, disables the watch dog timer, enables the power up timer and disables code protection. The
programming software currently defaults to 3FB1H. Consult Arizona Microchip Technology for more
information on the Configuration Word.
c) The “blank check” command (B) only looks at the first location. A programmed device will always
have data in this location as it is the program start address.
d) For each of the commands B, P, R and V the user will be prompted to manually reset the target µC,
by pressing the RESET switch (SW1) on the EV8680 Evaluation Board. This is because PIC
programming always starts from location 0000 and the program counter can only be incremented.
e) Pressing A will display the program data in the bottom window, formatted in pages of 48
consecutive locations. Use the <PageUp> and <PageDown> keys to scroll through the data.
Pressing <Esc> will return the user to the >ok prompt.
f) Programming a blank PIC16LC76 using the PICPROGB software takes approximately 2 minutes.
g) Customers are advised to use PIC16C76JW µC devices (not supplied) for further PIC firmware
development, however, these devices are not guaranteed for low volt operation. Customers re-
programming this development PIC must erase the existing program by placing the device in a UV-
Eraser for approximately 15 minutes.
TO LEAVE PROGRAMMING MODE
a) Remove power from board (including the programming voltage, VPP).
b) Remove 2-way jumper connecting MODEA to MODEB.
c) Power up board as described in previous sections for normal operation.
1.6.4.2 Terminal Emulator
Users will need to run a suitable terminal emulator on their PC in order to communicate with the PIC
µC on the Evaluation Kit. ‘Hyper Terminal’, which is supplied with the Windows 95/NT installations, is
suitable for this purpose.
