Re: Thermometer project using Mikroe 7seg Click (2x 74HC595) and Mikroe Thermo 4 Click (LM75B)

Thank you, now it works as expected! :)
I am posting the code for my little project, enclosed, so that everyone can see it.

Thermometer with 2x 7segs and 2x 74HC595.fcfx

Is it okay for the LM75B I2C's address to be hardcoded, or should this component be changed to allow a custom address ...

Re: Thermometer project using Mikroe 7seg Click (2x 74HC595) and Mikroe Thermo 4 Click (LM75B)

Hi Bijumon,


I have followed your instructions and moved the A0 jumper to VCC. The new setup works! :geek:
Now I have a different problem. In my earlier interactions with the Mikroe 7seg Click display, I found that:

DP is on Q0 of 74HC595
B is on Q1 of 74HC595
A is on Q2 of 74HC595
... and the ...

I can't make it to work. Enclosed is what I have tried... :roll:

Also, regarding LM75B, with A0 = A1 = A2 = GND, the LM75A uses the default I²C address 0x48.

I have enclosed the schematic of Mikroe Thermo 4 Click.

Thermometer project using Mikroe 7seg Click (2x 74HC595) and Mikroe Thermo 4 Click (LM75B)

Hi,


I have been trying for a few hours to build a thermometer using the Mikroe 7seg Click and the Mikroe Thermo 4 Click, both connected to an Arduino Uno, but I cannot get it to work. What I need is to display the temperature reading from an LM75B using 74HC595 shift registers.

Re: Kitchen Timer project using Mikroe 7seg Click (2x 74HC595)

Here is more information about my project. The timer will show the following minute intervals:

1-10': one-minute steps
10-30': five-minute steps
30-60': 15-minute steps

The timer shall start with a blank screen.

If you press the PB1 button once, number 1 will appear. The timer will count for 1 ...

Re: Digital clock using ATmega1284P, 4x 7-digits + DP, RTC and temperature

ATmega328P should be enough for my project, while ATmega1284P might be overkill for a digital clock. :)

I tried using the Atmel ICE programmer with Flowcode, but I couldn't program the microcontroller on the breadboard I built. I went back and installed Microchip Studio, then MPLAB... then Visual ...

Re: SN74HC595 Multiplexed 7 seg LED display

Hi Martin,


I am now working on a digital clock with an Arduino Uno, a DS3231 RTC, a TPIC6B595 (for high-current support), and a display called TDCR1050M (common anode), just to avoid a lot of wires and... because I like the display, the idea of using shift registers, and I like a scalable design ...

Re: Digital clock using ATmega1284P, 4x 7-digits + DP, RTC and temperature

Hi,

I have abandoned this project because I will build it with an Arduino Uno and a TPIC6B595 display component, for which I received help here on the forum:

https://www.flowcode.co.uk/forums/viewtopic.php?t=3636

I was not able to program my board using the Atmel ICE programmer, so I went back to ...
