PSoC 5, 3 & 1 MCU

New Contributor II

Hello, Can anyone help me convert this ancient 8bit pic code to run on the PSoC 5?, Ideally I would like to use flash instead of EEprom, I do not know enough about the Pic code structure, 

start-up the very first time, RA4 (port A.4) is held high and
; thereby initializing the rec, pulse, wait time in the EE plume.
; If RA4 is low during takeoff, the EE plume is read instead.
; Note that RA4 has dual function as it at high (after
; start can be used (via RA0, RA1) to adjust the number of pulses
; REMEMBER to set low again before the next ON / OFF.
;

Unfortunately, I am not able to do this,

 

Thanks for your help

IaCa,

I recommend describing what you want to achieve instead. Will be simpler, than decoding unknown assembler code.

Hi, What I am wanting to achieve, is to create an adjustable pulse timing controller, capable of waiting before receiving (10uSec.),receiving pulses(0 .5mSec.) from a bilateral switch, and wait/hold(0.40msec.)before the next pulse, and delay (0.6msec.) and output to a quad CMOS Nand gate,  there is a lot of critical information withing the assembler code I do not understand ,

Kind Regards

IaCa,

It would be nice if you can draw a timing diagram for clarity. The specs seem to be manageable.
