Project Info
HF-6158 is used for various tentative projects and tests. Assembled on universal board can be easily modified, for example microprocessor can be changed for ATMEGA128 or similiar.
This system has the following features:
THOS-1 operating system
Embedded HAVR8 compiler and interpreter
48 I/O pins (PORTA-PORTF) available as external ports
5 I/O pins (PORTG) only for extension board devices
HF-10060 programming interface
Reset button
Function button
Function LED
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
Buzzer (CW output device)
Potection against reversed supply polarity
In practise I rarely need to switch output channel to UART OUTPUT DEVICE, I can handle all commands on CW OUTPUT DEVICE which is 24 WPM telegraphy.

Software:
In current software version 1.21 there is 196 functions available for user (code size 17.7 KB), these are THOS-1 system functions, some drivers for various hardware inherited from older systems like HF-6030, HF-6048 and HF-6050 and some new developed functions and drivers. I still prefer writing for AVR than newer ARM processors. For some old equipment there is no need to use 100 MHz processor, 16 MHz AVR will do the job quite well because it is 5 times more efficient than INTEL 8x86 processors. All code has been written in pure assembler what is time consuming but very efficient in generated code size. Source code for these 17.7 KB exaecutable code is more than 20 000 lines in more than 100 files (in assembler there is almost 2 source code lines for one generated byte).
For that reason capitalistic commercial programmers will never write code in assembler. It is too good and efficient for Capitalistic Regime. Their goals are other, huge and unefficient code where various bugs end exploits can be hidden for invigilation of capitalistic society by their oligarchic masters.
Hardware version changes:
Version 1.4: introduced function LED2 which is logically connected with function switch SW2. When user calls function Wait_for_function_button LED2 is flashing with 1 Hz period untill SW2 is pressed. I found this helpfull to "synchronize" user to various processes when system must wait for user answer.
