PIN CHANGE Interrupts

Hi All, I'm gradually getting into PIN CHANGE Interrupts, so far so good. However I've come across a small issue which I cannot seem to find any info about ... Question: How do I check for a Pin Change on the RESET Pin ? I can find it in the PCIE1/PMSK1(Bit 6)/PCINT14 Tables, but get errors whenever...

Re: High Accuracy DS3231 RTC & EEPROM (HCMODU0094)

Hi Andrew, Thought I'd use the Forum for this, maybe stupid, question. I use DS3231 & DS1307 RTCs a lot for the Projects I do. But I have now reached the point of requiring the 'Time' data down to 1/100 second or better. Q1: Are/is there a way of getting second times at this level from either of the...

Re: HCMatrixkeypad - Matrix keypad library

Hi Andrew, Thanks for the efforts yo are making, very much appreciated. For what it's worth, please don't keep 'faffing around' with it --- it's not worth it. All I need to do is remember to just hit 'my' version of Ret Key( # ) then do a reload from EEPROM and everything is back to where it should ...

Re: HCMatrixkeypad - Matrix keypad library

Hi Andrew, Sorry to be a nuisance, but I have just run a couple of silly Tests. As you know I run Win XP-Pro sp3. T1: Compile using IDE v1.0.6 - RET CODE error does NOT occur; repeat does NOT occur. T2: Compile using IDE v 1.8.9 - RET CODE error DOES occur; repeat DOES occur. To me that points to so...

Re: HCMatrixkeypad - Matrix keypad library

Hi Andrew,

Sorry to say it does the same, 1st RET CODE is always 'Pick a Number', after that Perfect.

All I can say is Very Strange.

However, could it also be a pointer to Win XP OS ?

Regards S.

Re: HCMatrixkeypad - Matrix keypad library

Hi Andrew / All, General question as I am experiencing a little issue with the 4x4 Keypad. All the keys work fine, all RET Values are fine - Except for the VERY FIRST returned Value. The only way I can describe it is for you to PICK any number between 0 & 255 - that is what I get. After that, I get ...

Re: HX711 Bridge Sensor Digital Interface Module (HCMODU0073)

Hi Andrew,

Makes sense, didn't want to power the Bridge only to get no reading.

Re: HX711 Bridge Sensor Digital Interface Module (HCMODU0073)

Hi, Is the E+ & E- ( AVDD & GND ) pre-connected to the 711 ic ? I have measured an Output of 3.8v on E+ with 5.20v applied to VCC, or will E+ vary dependant on A+/- Inputs. I don't really want to connect the Wheatstone Bridge to AVDD if the voltage will vary - this is for a Pt100. Simply trying to s...

Re: 12864B Parallel/Serial Graphic LCD Module (HCMODU0032)

Hi Andrew and thanks for the reply. Yes, the answer was concise enough. I understood before about the Character/Graphics - either/or - modes, think I will need to re-evaluate how I can do what I need as I require both of the Modes on the same screen. Anyway, the actual screen is good, displaying wha...
