The three most common reasons
why you can't program a micro in the DT006 Board.
-
Cable not correct. It must be
a 25 wire cable.
-
Software configuration not correct.
In Bascom, it must be the Sample programmer.
-
Printer Port not set correctly
in your PC Bios.
Any PC parallel printer port
can be used to program the chip. You will need a DB-25-male to DB-25 female
cable with at least pins 2, 4, 5, 11, and 25(Gnd) connected straight through
between the DB-25 male and the DB-25 female. Standard DB-25 male to female
extension cables that have all 25 wires connected straight through, are
fine for this job.
Having trouble programming
a SimmStick with the DT006? Read J14 again:
J14 MOSI/MISO in/out crossover
to Simm Bus.
4 pin (2 x 2) header. Two
Links.
To
be able to program a SimmStick via the Simm Bus, you will have to link
J14 pin 1 to pin 2, and J14 pin 3 to pin 4. This means the links must be
horizontal, or point towards the Simm socket. If you need to swap these
signals, simply position them vertical.
Having trouble programming
a SIMM100 SimmStick with the DT006? Read the SIM100 instructions again.
You need to install jumper
J6 (Rev.B board only) or jumper pin 1 & 6 of IC3 (Rev.A board only)
, so the reset signal reaches the microcontroller. You can't reset
the MCU "outside" of the SIMM100 board which is neccessary for programming.
What you can do with the SimmStick slots?
