Evaluation Kit User Manual for FX828 and FX829
EV8000
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 to 3FB9H if it is a PIC
16C74JW or 16LC74JW, or to 3FB1H if it is a PIC 16C74AJW or 16LC74AJW. In each
case, 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 µC 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.
1.6.4.2 EF8000 Firmware
The PIC µC is supplied pre-programmed with EF8000 firmware, which is used to convert the
RS232 serial interface into a C-BUS interface. It also executes some of the higher data rate
commands and collects high speed interrupts for pre-processing, before passing these back to
the PC. Its operation is transparent and it is controlled by the ES8000 Windows Application
Software.
1.6.5 Known Bugs in the ES8000 (Version 1.0) Software
The warnings highlighted in Sections 1.6.3.20 and 1.6.3.22 should be followed to prevent any
Windows application failures.
