How to configure ADC of PIC18F45K80

Hi I have started working on PIC just before one month. I am reading datasheet of PIC18F45k80 for ADC Module. ADCON0 information is given in chapter 23. Page 350 I want to make AN0 and AN1 pin analog pin for joystick and other should digital pin AN0 and AN1 is default analog pin so I do not unders..

What can we do with CAN and LIN?

Hello Guys,I find that they are shown to work with cars -Controller Area Network (CAN) and Local Interconnect Network (LIN) As you know, developing a product to work with car is not simple. One must work in the car manufacturers or have much resources and equipments to test on cars. Now, I raise a q..

New to XC8 & I have a question ...

Hello ... I have been forced to move over to XC8 from assembly (because of MPASM has been discontinued) & have been working my way test programs in C to change my existing controllers over. Presently I am using a pic16f18877 where I am setting up a CCP2 with the MCC ... everything is working BUT..

Decoding AC-3 (Dolby)/DTS?

Open-source implementations of those, ie liba52 has existed for a long time. Does any code or libraries exist for Microchip chips? The requirement is to read an S/PDIF stream and break it into individual 5.2 or 7.2 channels as I2S or S/PDIF. Is this doable? Yes, I know that there are special chips f..

MplabX does not recognize some XC8 2.xx predefined macros

Hello. While I was doing some experiments with inline assembly, I needed to know how much instruction words BANKSEL instructions would use. To calculate it, I am using the predefined macro "_BANKCOUNT_", and everything works as expected. But I have a very annoying problem with the MPLAB X IDE, it do..

Use MCLR Pin (RA3) as input with low-voltage programming?

Development Environment: MPLAB X IDE using asmDevelopment Board: Curiosity DM164137Processor: PIC12F1572 I want to use RA3/MCLR as an input. In order to do that, I need the configuration bits to be:MCLRE=0LVP=0 I can’t program the pic with MPLAB X IDE/DM164137 until I set LVP=1. Therefore I can’t pr..

PIC32MX795: SPI master with RX and TX interrupts

Hey guys. I am using a PIC32MX795F512H with a 1MHz SPI, trying to communicate with slave. Usually there's four bytes in order to read a register, but the length is not fixed to four in general. Right now, it goes like this: Put four bytes in an array, set the number of bytes I want to send and then ..

Does anyone? X..
