--------------------------------------------

mim module source code released.

-----------------------------------------

subject: [amsat-bb] mim module source code released.
from: "robert bruninga" <bruninga@xxxxxxxx>
date: thu, 10 jun 2004 2043 -0400

--------------------------------------------------------------------------------

the source code for the mim module has now been
released to encourage further production of this
small tnc aprs transmitter on a chip. this is the
same chip used in the mic-e project and the protocol
was later used in the d7 and d700 radios.

http://www.ew.usna.edu/~bruninga/mim2.html

the mim module was developed by wb4apr, n3mim,
and n3xlm and used in many balloon and small
satellite projects over the years.

it provides these tnc transmit functions:
* beacon text
* gps position data
* 5 channels of analog telemetry in aprs format
* up to 8 bits of parallel bit data
* full implementation of the mic-e format
* cw id for balloons

one of these modules is sufficient to provide all
the telemetry as used on pcsat, pcsat2, ande
and raft1 satellte missions. thus, they are
ideal for small satellites such as cubesats
pioneered at stanford.

by releasing the source code, we hope this will
encourage further production of these excellent
telemetry modules for tiny satellites.

网页内容 :

the mic-encoder was designed in 1994 by bob bruninga wb4apr and presented at dayton as a means for encoding aprs into a microphone on any radio. carl wick, n3mim at the naval academy finished the ax.25 encoding and we renamed it the mim module. will clement n3xlm tightened up the code and brought it into production as the mim2. this chip was used in the tapr mic-e project and th eprotocol was adopted later by kenwood in its d7 and d700 radios. in recent years, other pic processor projects have brought aprs to just about any mobile application. but only the mim module has flown in space and been used in hundreds of student balloon and satellite projects because of its 5 channels of analog telemetry in aprs format.
we want to see it remain in production for similar student aprs projects and are releasing the source code to give them flexibility in their designs. dozens of these have been used at the naval academy and at stanford small satellite lab.

aprs&reg; mim module features:

complete1200-baud, ax.25, tnc transmit operation.
telemeters 5 analog signals (8-bit resolution) and 8 digital bits of data.
telemeters aprs&reg; compatible gps position if a gps receiver is attached.
transmitsbeacon text and cw id (20 wpm).
user-selectable transmit intervals for each packet type
user-programmable digipeat path containing up to 7 hops.
all user selections (callsign, digipeaters, rates, btext, etc.) stored in eeprom
configuration changeable at any time using the supplied pc software via serial port.
has receiver "hold off" to avoid collisions.
all surface mount except for the pic16c73 for easy firmware upgrades. size: 1.0" x 1.7".
on-board regulator (6.5-40 vdc. less than 15 ma). can source an additional 85 ma.

mic-lite! build a half price mic-encoder! see also my sketches. and details

download the complete mim docs &reg; .

source code has been released to encourage their further development in the amateur satellite service.


download the source code . [we only ask that credit be given to the authors].

通过阅读source code,bd4os说的原板上多一个8pin ic的问题,可能是eeprom 93c66,连接到pic16c73的portc 2 3 4 5四pin。

需要两块93c66吗?电路图中已经有一块93c66,但板子上有两块8pin ic,不知道另外一块是什么?

再貼上一個 mim 及 pic-e 的線圖, 以供有興趣的 ham 參考.

(有人在做嗎? 呵呵)
