Project Info

HF-6128 is used for various tentative projects and tests. Assembled on universal board can be easily modified. System is active but assembly is not ended yet, various hardware and software modifications are still made, so final shape is not known yet...

This system has the following features:

THOS-1 operating system

Embedded HAVR8 compiler and interpreter

40 I/O pins (PORTA-PORTF) available as external ports

5 I/O pins (PORTG) only for extension board devices

PORTF keyboard interface (HF-17763 or HF-17966 type)

Extension board EEPROM 2KB 24C16 (DRIVE2)

HF-10060 programming interface

Reset button

Function button (planned)

LED supply voltage control

HF-10032 I2C interface (memory drives HF-1469, HF-1471, etc with THFS file system)

HF-10040 UART interface for communcation

HF-10082 SPI interface for communcation

RAM Module 32KB (HF-64115)

Buzzer (CW output device)

Protection against reversed supply polarity

XTAL 24 MHz option

Automatic motherboard recognision system

Systems HF-6128 and HF-6169 are first systems where automatic recognision of main board by microprocessor module are introduced. Thus microprocessor modules HF-12268 and HF-12269 can read digital signatures from EEPROM (DRIVE2) of extension boards HF-60268 and HF-60269 and apply "BIOS" software specific to hardware on these boards. All is done of course under control of THOS-1 operating system. This system will be introduced also in other systems with multiple microprocessor modules and motherboards.

Hardware version changes

Version 1.3: Added EEPROM 2KB 24C16 (DRIVE2)

Version 1.4: Added HF-10082 SPI interface for communcation, PORTF connector for external keyboard HF-17763 or HF-17966
