EV6240 Datasheet, PDF (29/47 Pages) CML Microcircuits – Opto-Isolated serial interface capability

Evaluation Kit for CMX624/CMX644A
EV6240
The user interface consists of two windows. The top window contains the operating instructions and
status information. The bottom window contains prompting and progress information plus user input.
When the top window first appears the user will be prompted to enter the number of the serial
communications port to which the EV6240 board is connected, and then, which device is to be
programmed. For the EV6240 board select option 2, PIC16C77. Once the user has entered this
information, the following commands may be selected:
Press F to load file
Press C to configure device.
Press B to check target device is blank.
Press P to program target device.
Press V to verify target device.
Press R to read target device.
Press A to view contents of program data array.
Press Esc to return to DOS.
A new function from the above table can be selected whenever the >ok prompt appears in the bottom
window.
Notes:
a) Assembler output 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 EV6240 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 the EV6240 PIC16C77 using the PICPROGB software takes approximately 2
minutes.
TO LEAVE PROGRAMMING MODE
a) Remove power from board (including the programming voltage, V_PP).
b) Set switch, SW3, to ‘OP’.
c) Power up board as described in previous sections for normal operation.
