Re: Problems choosing character size on 128x64 display

Hello Ben ! I'm using version 9. I noticed that the display has a certain delay to load the characters, which can be 1 or 2 seconds, depending on what you want to show. I did a test using an arduino nano (in serial mode, using the arduino code example) and saw that the data loads quickly into the di...

Re: Problems choosing character size on 128x64 display

Hello !! I am using real hardware. I always use simulations before testing in the real world, but my Proteus doesn't provide the component (display st7920) so I can test it virtually.

Problems choosing character size on 128x64 display

Hi. I'm learning to use 128x64 display (ST7920). But I'm having trouble modifying the size of the characters shown on the display. Regardless of what I do, the size is the same. Could anyone give any tips? I'm posting a flowchart that I set up to try to change the font size, but it doesn't change.

Re: Problems Using Interrupts on Atmega88

Hello Martin! I used your flowchart and adapted it for Atmega88. Worked perfectly ! I am very grateful for your willingness to have helped. You really took me out of a puzzle to make interrupts work. Thank you very much !

Re: Problems Using Interrupts on Atmega88

Hi. I'm trying to make the led blink to check if the interrupts are working. The second led blinks using a delay so I can see if the chip is really working (Because the breadboard connections are not so good and I can check if the chip is being powered).

Problems Using Interrupts on Atmega88

Hi. I'm recently testing an Atmega88 so far I've had a lot of problems. After a few attempts I managed to make a led blink (because I didn't know the chip settings well). But I can only make it blink using using pooling. Another port should be told using interrupts, but it doesn't work. I selected d...

Re: Multiplexing 7-segment 4-digit display with 74HC595

Hello, Medelec35! The number of the component in the proteus is 7SEG-MPX4-CA-BLUE. At a slow clock speed it is possible to notice that the digits light up at the correct time, but using the clock at real speed on the proteus the software cannot simulate. I am sending the proteus file attached.

Re: Problems reading the DHT11 sensor

I have corrected my flowchart. In the flow chart, I used humidity equal to 0. The loop operates until the sensor shows some humidity value above 20%, ie the loop works until the sensor can be read and "x" shows how many loops were needed to read the sensor. In actual hardware testing the lcd shows t...

Re: Measurement of temperature and relative humidity using DHT11

I also had problems, but using a DHT Sensor. Only later did I find out that I was using crystals of very low speed (4 and 8 MHz). My problem was solved with a higher speed crystal (20MHz).
