Infineon 80C535 based main board (v1)
This design is outdated and now replaced with version 2 with
more speed and versatility. See below.
DS88C450 MCU with LCD display (v2)
After two ligtning strikes I've decided it is time for new compact design
with few parts and all the features of the first design.
This system should replace all display and PCB of v1 with single compact
PCB with LCD display and high speed CPU.
Features
- Single side PCB option
- Two types od LCD display 2x16 and LCD graphical display (128x64)
option with flat cable and backlight control.
- Two one wire buses for DS1820 thermometers.
- I2C RTC with alarm and EEPROM.
-
- RS232 with In System Programming
- GPIO connector with 74HC595 serial expander
for infinite number of outputs
