Digital Output with PIC Microcontroller in Assembler Episode 034

We create a simple assembly (ASM) program to blink an LED using a PIC16F15213 microcontroller with a variety of system clocks. Calculating algorithms to generate precise delays requires some thought but can be quite satisfying. The batch of instructions we explore are MOVLW, MOVWF, DECFSZ, NOP and CRLWDT. #embedded #programming #digitalelectronics edit: near the end of the video, I misspoke (twice!) I meant to say 250 000 "Hertz", not kilohertz! edit #2: Also, I discovered an error in the code; we'll cover it in the next episode... 00:00 LED blink program review 02:35 Breadboard layout 04:18 Code assembly and programming 05:40 External clock source 07:03 Calculating instruction speed 10:42 General Purpose RAM register 11:44 MOVLW instruction assigns literal to Working register 12:44 MOVWF instruction copies value in Working to a file register 13:22 DECF instruction decrements the value in a register 14:07 STATUS register 14:50 BTFSS skip the next instruction if bit in register is set 17:06 8-bit loop counter calculation 22:57 Watchdog timer 26:03 8-bit loop counter timing tweak 28:23 NOP no operation instruction 29:36 DECFSZ optimizes DECF and BTFSS 31:52 16-bit loop counter calculation 40:04 Internal 31kHz low frequency clock 45:35 Internal 1MHz high frequency clock 47:59 Exposing the internal clock on an external pin Song: MANIA - Reason (feat.
