Re: W1209 Temperature control Switch (HCTHER0006)

The programmer is the Hobbycomponents STM8 & STM32 EMULATOR AND PROGRAMMER - Model HCDVBD0016 http://hobbycomponents.com/st-micro-electronics/444-stm8-stm32-emulator-and-programmer I have traced the 4 pin header from top to bottom, located to the left of the LED. Pin 4 is the GND at the board edge. ...

Re: W1209 Temperature control Switch (HCTHER0006)

Reset to default is actually done by holding + and - and then powering up. This module is super value and functional. Even better is the STmicroelectronics microcontroller STM8S003F3P6 is wide open and can be programmed as a development system in C, asm and even FORTH! Caveat emptor, though, for war...

Re: Tiny RTC DS1307 + 24C32 Real Time Clock Module (HCMODU00

Hi, I just opened up my HC RTC from May 2014, and had it working in minutes with a Micromite MkII with I2C. The MMBasic is smart and knows the type of RTC connected, avoiding all of the frustrating (=Arduino headers, libraries, compiler) :cry: I2C setup. The Micromite MkII is a home programmed (OS f...

Re: Display the DS18B20 unique rom ID on a LCD & the tempera

Hi, I changed the clock to the actual 4Mhz from 20, the temperature displayed is 60 to 100 deg to high.
Could I ask for a text copy of a working :? <DS18B20.h> being posted?
Many thanks,

Re: PIC - PIC Development Board + PIC16F877A (HCDVBD0003)

i just used one of these and erased the led flashing programe on the pic chip which came with it ,where can i find it again to load it up ? I believe that test program is flashed into the device by the factory when board is tested. I'm about to add an example blink program to the first post. Unfort...

Re: Multifunction shield for Arduino Uno (HCARDU0085)

Playing with the DS18B20 1-Wire Digital Thermometer required a bit of research. One could make a career out of this one chip. :geek: The TO-92 chip sits in the 3 machined sockets U5 closest to J1 jumper. J1 feeds 5v to a 10k resistor R5 and the centre pin DQ. The silkscreen layout is correct with th...

Re: Multifunction shield for Arduino Uno (HCARDU0085)

To turn on a designated Decimal Point, the segment map can be expanded with ten more values. Simply replace the following lines. A-OK on the 0x7F mask, I posted and then read your comments. We all can benefit from this forum. const byte SEGMENT_MAP[] = {0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,0X80,0...

Re: Multifunction shield for Arduino Uno (HCARDU0085)

Looking at the schematic, it looks like it doesn't have decimal point support, is that correct? An alternate segment map is required for the affected digit. Try this and see all DP turned on. const byte SEGMENT_MAP[] = {0x40,0x79,0x24,0x30,0x19,0x12,0x02,0x78,0X00,0X10}; // msb (most significant bi...
