xxx-README 3 prop test configuration.txt Popforth 4.0a 20101212 DAW

PropForth should run on just about any configuration. 

Built a reference 3 prop system for testing:

Propeller Prototype Board, 5 MHz 64kx8 eeprom.
40 Pin Dip prop chip  added to this board.
spinneret board connected to the Prototype board.

NOTE: the 220 ohm resistors are to limit current in the case of SW misgonfiguration, anything from about 100 - 400 ohms
is suitable. Any larger values will slow down the edges, and can cause problems with the serial and com drivers.

This part of the configuration allows for testing of the norom boot, the serial driver, and the com synchronous
communication driver.

Prototype - the master is a propeller protoboard @ 5 MHZ with a 64kx8 rom,
with a FTDI USB->rs232 attached to the header

Add a prop chip, used a 40 pin dip
Run power and ground 2 0.1 uF caps between the power and ground pins, close to the chip

10k pullup resistor on  IO 29 - the pin normally hookup up to sda on the eeprom

Protoboard			Prop Chip	
IO 8 	-> 220 ohm resistor 	-> IO 28 (this pin normally hooks up to scl on the eeprom)
IO 9 	-> 220 ohm resistor 	-> IO 29 (this pin normally hooks up to sda on the eeprom, 10k pullup resistor as well)
IO 10	->			-> RESET
IO 11 ->			-> XI

This is a serial port connection so we can talk to PropForth on the Prop Chip serially if we so choose

IO 0	-> 220 ohm resistor 	-> IO 30
IO 1	-> 220 ohm resistor 	-> IO 31



These connections are made to the header on the Spinneret board.

IO 12	-> 220 ohm resistor	-> IO 30
IO 13	-> 220 ohm resistor 	-> IO 31
IO 14	->			-> RESET
GND	->			-> GND
