RS232 I2C Adapter (Master)

The RS232 I2C Adapter is an universal applicable I2C-tool with a 128 bytes of buffer and a SCL-frequency up to 400 kHz. With the RS232 I2C Adapter as master numerous bus participants can be adressed such as IOExpander, sensors, LCDs, 7-segment display, stepping motors, AD/DA converters, real time clocks, tone generators, RAM, EEProms, etc.

The Tool is ideally for the developer, who would like to develop and/or test own I2C circuits. The SCL frequency can be adjusted between 15 - 400 kHz. The frequency depends on the Adapter’s type.

Following are the different types we offer:

200kHz: SCL-frequency adjustable between 10 and 200kHz. Needs external power supply of 5V.
400kHz: SCL-frequency adjustable between 12 and 400kHz. Needs external power supply of 5V.
LowPower: SCL-frequency adjustable between 1 and 100kHz. No separate power packs for voltage supply are needed. Power supply is provided from the RS232- Interface (DTR & RTS).
Power consumption less than 5mA.

The pertinent software contains already modules for above- named I2C-IC's and other user defined IO-interfaces.

Some I2C-IC's are already integrated in the software e.g.

Temperature sensor
IOExpander
AD/DA converter
Real Time Clock
4 Dig LED 7-segmen display
I2C LCD Adapter
RAM
EEPROM
and there are ever continued to extend.

The software has in addition other modules like "Adavnced mode", so it is possible for users to be able to address any I2C-IC. As much as desired read/write instructions can be inserted in a table and with a mouse-click all instructions will be executed. The option for repeating all instructions is also present. Up to 128 bytes per I2C-Message can be written or read.

With the Delphi components "TSerI2C, TSerI2CDev" or the DLL "SerIIC32.dll" it is possible to integrate the adapter into own applications.
