#### Re: MCP3201 problems

Hello Fratello,

Sounds like a hardware issue. I worked with LM2931 and i had some strange problems because I used a lower capacitance on output. Connect a 100uF (0,1uF is too low) near the stab...

#### Re: how to calculate reverse value with scale

or

should do it. Where I assume you are reading 130 to 30.

Thus, a reading of 130 will give output = 0
and a reading of 30 will give output = 100

#### Re: how to calculate reverse value with scale

should do it. Where I assume you are reading -130 to +30.

Thus, a reading of -130 will give output = 0
and a reading of +30 will give output = 100

#### how to calculate reverse value with scale

Hi,

I cannot find how to convert my level value from receiver (from -130dBm to -30dBm) I do not use minus -> so 130 to 30
My display (nextion type) has a "vu meter" witch needs 0 to 100
When...

Richard:

Thanks for your response. I modified your program to use with a 18F14K22, and since I have a serial LCD backpack, I changed the LCD stuff to SEROUT2. Also, no PB3 here, still on 2.6,...

#### problem with LCD large Numbers

Hi all
I have been away for a LOONG time, finally getting back working with PICs.

I have developed a program to display large numbers on a 4x20 LCD, using PBP 2.6. The PIC is an 18F14K22.
I...
