Finally, at the end, this was be the answer: " volt=(ADRESH << 8) | ADRESL; // Calcular la resistencia desconocida usando solo aritmética de enteros, float no, long no en 12f675 r_x = (unsigned int)((unsigned int)100 * volt) / (1023 - volt); " It give it to me, the same result as multimete...

Changed R fixed from 330 to 100 ohms, and measure values to max 100 ohms: volt=((unsigned int)ADRESH*256 + ADRESL)*5; res= ((100 * volt) /(5000 - volt)); I´ve upload some values: Real v Oled R Oled V Calc 21 10 1095 29 33 13 1300 35 82 19 2280 83 100 24 2550 104 Where: Real v: are the color code fro...

Thx for answer steve. If i put a know value (res=9876), it shows fine. So maybe the calculation is the bad thing Edit: If i made the real calculation, "res" calculation, is a negative answer, because volt it´s a 4 digits value (not less 5v value), so, if i have 4v, volt is equal to 4000, n...

The variables are declared: unsigned char d[4], i; unsigned int volt, res ; And used: A) Not working: for(i=0;i<4;++i){ d =res %10; res=res/10; } drawChar4(d[3], 0, 0); drawChar4(d[2], 0, 2); drawChar4(d[1], 0, 3); drawChar4(d[0], 0, 4); B) Working: for(i=0;i<4;++i){ d =volt %10; volt=volt/10; } dra...

Thx for answer Martin! I´m using C code, and a pic12f675, founded how to run with ssd1306, the example that i´ve found, it´s a volmeter, but i want to made a Resistometer, =). The mats are: volt=((unsigned int)ADRESH*256 + ADRESL)*5; And i´ve add: res= ((330 * volt) /(5 - volt)); But the value res s...

Hi!

I´m new in FC, i´ve come from niple soft, stm32 and pi pico.

I´ve download the file that mnfisher upload, when i´ve try to compile, it says error:

Unknown or missing component: Potentiometer1::GetByte()

Do you know why?


Thx!
