![]() I am not an employee if Microchip and they could not pay me enough to do this for them. There are some things you need to learn about setting up an assembly language project in MPLABX that Microchip has not document in enough detail yet. If you can please get a copy of the entire MPLABX project from my git repository. ![]() Movf BANKMASK(tmp),w yes - record this new high value Subwf max,w is this value larger than max? * find the highest PORTB value read, storing this into the object max */ PSECT MainData,global,class=RAM,space=1,delta=1,noexec PSECT Isr_Data,global,class=RAM,space=1,delta=1,noexec Data space use by interrupt handler to save context GND -> 5 : GND VDD : 14 6 : RB0/INT PGD/RB7 : 13 ICSP_PGDĬonfig FOSC = HS Oscillator Selection bits (HS oscillator)Ĭonfig WDTE = OFF Watchdog Timer (WDT disabled)Ĭonfig PWRTE = OFF Power-up Timer Enable bit (Power-up Timer is disabled)Ĭonfig CP = OFF Code Protection bit (Code protection disabled) 3 : RA4/T0CKI OSC1 : 16 4 : MCLR OSC2 : 15 -> 4MHz crystal Add this line in the project properties box, pic-as Global Options -> Additional options: Example project for the PIC16F84A controller using the pic-as(v2.20) tool chain. To help I have crafted a PIC16F84A example project you can find here. Microchip has made it very to hard to develop 8-bit assembly language applications using the latest release of MPLABX v5.40. I just created a new assembly file ( FooFile.asm) with three lines of instruction - org, clrw and end.
