Short: I2C-bus hard/software interface project. Author: Brian Ipsen and Wilhelm Noeker Uploader: wnoeker@t-online.de (Wilhelm Noeker) Type: hard/hack This shared library will allow easy access to integrated circuits with the I²C-bus interface. Included in the archive are: - Schematics for interfaces (several to choose from) that connect I²C chips to the Amiga - AutoDoc description of the library functions - C headerfiles for GNU, Maxon and SAS/C For non-profit purposes, i2c.library is postcard-ware. All other use requires explicit permission from either of the authors. History ------- V40 re-release (Jan/99): - Better installation script, now also works with older Installer versions - Minor corrections to the documentation Changes from V39 to V40: - Default bus timing (i.e. the delay value used until a client program explicitly calls SetI2CDelay) can be set by means of an environment variable (I2CDELAY). - Library exposes a base structure with performance counters and interface type information - Additional schematics for an I²C interface on the floppy port - More code samples - Installer script Changes from V38 to V39: - Support for I²C interfaces on either parallel or serial port - Better support for multitasking access to the library (for example, in order to control different chips attached to the same I²C bus) - Better error diagnostics - Easier initialization - New method to ensure the proper bus timing ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 1233 592 51.9% 12-Sep-98 15:36:48 +bin.info 13848 8111 41.4% 24-Aug-98 21:17:58 +I2CScan 3015 474 84.2% 12-Sep-98 15:31:56 +I2CScan.info 10760 6228 42.1% 28-Mar-97 14:39:36 +ReceiveI2C 10196 5878 42.3% 28-Mar-97 14:37:40 +SendI2C 1233 595 51.7% 10-Sep-98 22:14:52 +Developer.info 6315 2696 57.3% 30-Aug-98 10:01:22 +ChangesV39 1391 507 63.5% 13-Aug-98 22:25:56 +ChangesV39.info 1502 792 47.2% 10-Jan-99 13:58:52 +ChangesV40 1391 507 63.5% 13-Aug-98 22:25:56 +ChangesV40.info 1188 548 53.8% 13-Aug-98 22:25:56 +fd.info 385 217 43.6% 16-Mar-97 12:16:44 +i2c_lib.fd 1188 543 54.2% 13-Aug-98 22:25:56 +GNU_include.info 575 314 45.3% 16-Mar-97 12:41:00 +i2c_protos.h 1162 398 65.7% 16-Mar-97 12:41:30 +i2c.h 3414 1464 57.1% 30-Aug-98 10:05:56 +i2c.h 227 151 33.4% 07-Sep-97 12:07:26 +i2c.h 494 250 49.3% 29-Jul-98 18:46:14 +GNU_Install 1572 956 39.1% 13-Aug-98 22:25:56 +GNU_Install.info 8939 3090 65.4% 04-Sep-98 19:56:22 +i2c.doc 1811 1292 28.6% 13-Aug-98 22:25:56 +i2c.doc.info 4375 1774 59.4% 30-Aug-98 10:05:16 +i2c_library.h 591 276 53.2% 13-Aug-98 22:25:56 +i2c_library.h.info 1188 540 54.5% 13-Aug-98 22:25:56 +MAXON_include.info 451 247 45.2% 07-Apr-97 21:35:16 +i2c_protos.h 3414 1464 57.1% 30-Aug-98 10:05:34 +i2c.h 639 274 57.1% 11-Aug-98 22:11:46 +i2c_lib.h 367 200 45.5% 07-Apr-97 21:34:30 +i2c.h 1487 810 45.5% 10-Jan-99 13:57:00 +i2clib40.readme 1391 506 63.6% 10-Sep-98 22:14:52 +i2clib40.readme.info 6577 2305 64.9% 04-Jan-99 20:29:42 +Install 720 372 48.3% 04-Jan-99 20:36:50 +Install.info 1233 599 51.4% 11-Sep-98 18:55:02 +Intro.info 5084 1974 61.1% 30-Dec-93 16:09:20 +fig1-two_wire.iff 1765 1220 30.8% 11-Sep-98 18:55:02 +fig1-two_wire.iff.info 4996 1999 59.9% 30-Dec-93 21:39:56 +fig2-wired_AND.iff 1765 1221 30.8% 11-Sep-98 18:55:02 +fig2-wired_AND.iff.info 2080 873 58.0% 30-Dec-93 21:39:56 +fig3-bit_timing.iff 1765 1221 30.8% 11-Sep-98 18:55:02 +fig3-bit_timing.iff.info 4420 2358 46.6% 30-Dec-93 21:39:56 +fig4-packet_timing.iff 1765 1221 30.8% 11-Sep-98 18:55:02 +fig4-packet_timing.iff.info 13798 5995 56.5% 10-Jan-99 13:48:04 +ReadMe.doc 15073 6352 57.8% 10-Jan-99 13:48:08 +ReadMe.guide 1817 945 47.9% 11-Sep-98 18:55:02 +ReadMe.guide.info 1233 595 51.7% 12-Sep-98 15:36:52 +libs.info 1644 1130 31.2% 24-Aug-98 21:12:36 +i2c.library.card 1972 1361 30.9% 24-Aug-98 21:12:38 +i2c.library.disk 1728 1210 29.9% 24-Aug-98 21:12:38 +i2c.library.par 1736 1214 30.0% 24-Aug-98 21:12:38 +i2c.library.par2 1728 1209 30.0% 24-Aug-98 21:12:38 +i2c.library.par3 1708 1189 30.3% 24-Aug-98 21:12:38 +i2c.library.ser 1720 1203 30.0% 24-Aug-98 21:12:38 +i2c.library.ser2 1716 1200 30.0% 24-Aug-98 21:12:38 +i2c.library.ser3 1716 1201 30.0% 24-Aug-98 21:12:38 +i2c.library.ser4 1233 593 51.9% 10-Sep-98 22:14:52 +Schematic.info 7670 3232 57.8% 13-Sep-98 08:13:26 +Floppy.iff 1765 1220 30.8% 13-Sep-98 08:14:22 +Floppy.iff.info 5224 2386 54.3% 02-Feb-94 16:34:22 +Parallel.iff 1765 1219 30.9% 30-Aug-98 11:34:50 +Parallel.iff.info 3871 1897 50.9% 10-Jan-99 13:56:10 +README 1391 501 63.9% 30-Aug-98 11:34:50 +README.info 6972 2993 57.0% 25-Aug-98 21:25:28 +Serial.iff 1765 1219 30.9% 30-Aug-98 11:34:50 +Serial.iff.info 1233 589 52.2% 12-Sep-98 15:36:38 +src.info 2849 1023 64.0% 02-Aug-98 16:17:52 +Dial.c 8728 2977 65.8% 24-Aug-98 20:36:14 +I2CScan.c 2833 1097 61.2% 06-Sep-97 15:57:36 +LED.c 619 203 67.2% 06-Sep-97 17:53:20 +LED.h 1999 781 60.9% 20-Aug-97 20:37:46 +LEDclock.c 1277 711 44.3% 06-Sep-97 18:51:26 +LEDclock.o 6357 2092 67.0% 24-Aug-97 00:33:30 +LEDgame.c 2388 900 62.3% 23-Aug-97 16:30:56 +LEDmsg.c 484 233 51.8% 22-Aug-98 08:59:02 +makefile 293 191 34.8% 22-Aug-98 12:30:50 +music 4298 1612 62.4% 22-Aug-98 12:29:32 +Play.c 1890 936 50.4% 10-Jan-99 13:04:10 +README 1391 503 63.8% 12-Sep-98 15:33:50 +README.info 1502 728 51.5% 28-Mar-97 14:35:24 +ReceiveI2C.c 1563 710 54.5% 02-Aug-98 13:58:10 +SendI2C.c 7429 2308 68.9% 10-Jan-99 12:48:50 +VPS.c 1233 593 51.9% 09-Jan-99 09:43:50 i2clib40.info -------- ------- ----- --------- -------- 245523 115308 53.0% 13-Jan-99 19:15:26 81 files
