Re: TMP102 Digital Temperature Sensor Module (HCMODU0100)

A bit of further work on this one - trying to get a temperature logger to work, I found that polling at regular intervals gave the same temperature every time, even if I breathed on the sensor to heat it up. After a bit of head-scratching (and a trial of the Sparkfun example sketch) I found that the...

Re: SD Card Module (HCARDU0008)

Thanks for the information and feedback. Just one quick comment about not using level shifters, in my tests I've found that the card can randomly corrupt so I wouldn't use a card, or put anything on it I wouldn't want to lose. Ah, thats whas happening! I've had file corruption a couple of times, fi...

Re: SD Card Module (HCARDU0008)

Had this knocking around in my bits box since I bought it a while back. Worked OK no issues, didn't use a level shifter and it hasn't blown up yet, though I did connect it to a 3.3v supply from my Arduino, whether that makes a difference or not I don't know. The card I used was an old Sandisc Ultra ...

Re: I2C Library for Hobby Components SmartLCD (HCMODU0122) Scrolling?

Are there any plans to include scrolling commands to this library?

Re: TMP102 Digital Temperature Sensor Module (HCMODU0100)

Hi there - Initially I coud only get a reading of 0.00 as the temperature using the sample sketch provided. However I discovered that the call to the routine I2CReadInt() was commented out, so I changed the following piece of code (lines 65 - on) to readas follows (change is in bold, the comment ter...

Re: Serial I2C LCD 1602 Module (HCARDU0023)

Hi Andrew, thanks for the prompt reply. Cut and paste it is then oh well ... All working very well now thanks, and very pleased with it. PS - Somehow my libraries got mixed up - I had one called "HCARDU0023_LiquidCrystal_I2C_V2_1" from somewhere, now done some juggling and the line "lcd.begin();" no...

Re: Serial I2C LCD 1602 Module (HCARDU0023)

Having struggled a little getting this to work e.g. code bugs such as the line lcd.begin();, which gave the IDE indigestion until I found it should be lcd.begin(16,2);, and finding, using I2C Scanner that the address is 0x27, not 0x3F (mine has the 3 pads on the back), plus a few other bugs I can no...
