setFontMode with the u8g2.print

[303055]

Hi olikraus

https://github.com/olikraus/u8g2/wiki/u8g2reference#setfontmode

How can we use the setFontMode with the u8g2.print ()? // u8g2.setFontMode(0); u8g2.setDrawColor(1); u8g2.print(a); // Not working

Thx

Hi,

I can not use the clear buffer because I have another function that works at the same time. I try lot of settings and I start to desperate ...

I use the full graphic mode: U8G2_ST7920_128X64_F_SW_SPI u8g2 (U8G2_R0, 13, 7, 6, 8);

I try with a: u8g2.setFontMode (0); u8g2.setDrawColor (1); u8g2.drawStr (11,23, "");

before the variable : u8g2.setFontMode (0); u8g2.setDrawColor (1); u8g2.setCursor (11,23); u8g2.print (a);

without success :/

an idea ?

Thank you in advance

[olikraus]

can you send a complete example?

Hi olikraus,

Yes of course : (PZEM004T is used to measure the current )

`#include

include

include

include

PZEM004T pzem(10,11); // (RX,TX) connect to TX,RX of PZEM IPAddress ip(192,168,1,1);

U8G2_ST7920_128X64_F_SW_SPI u8g2(U8G2_R0, 13, 7, 6, 8);

void setup() { pzem.setAddress(ip); Serial.begin(9600); u8g2.begin();
}

void loop() {

float p = pzem.power(ip);

u8g2.setFont(u8g2_font_crox5hb_tf ); u8g2.setCursor(11,23); u8g2.print(" "); u8g2.sendBuffer(); u8g2.setCursor(11,23); u8g2.print(p,0); u8g2.sendBuffer(); Serial.println(p,0); delay(10);

thx in advance

ok, but what is the problem with the font?

I mean, there are some other problems, like you do not clear the screen and the buffer is send twice (which is useless)..

A better version would be this:

void loop() {

float p = pzem.power(ip);

u8g2.clearBuffer();
u8g2.setFont(u8g2_font_crox5hb_tf );
u8g2.setCursor(11,23); u8g2.print(" ");
u8g2.setCursor(11,23); u8g2.print(p,0);
u8g2.sendBuffer();
Serial.println(p,0);
delay(100);

}

Hi

Now it work!

It was a bad understanding of the bookstore on my part I thought it was necessary to send after clear: u8g2.clearBuffer (); u8g2.sendBuffer ();

but no! just in the loop: u8g2.clearBuffer (); // write ... u8g2.sendBuffer ();

Sorry to annoy you for a bad read ..

Thank you for all your work

And thank you for answering me
