Serial comms / Bootloader
Good day
I have setup my circuit to be able to do serial comms as well as bootloader software as described at this thread:
http://www.picbasic.co.uk/forum/show...ght=bootloader
And have used Mister_e's code here:

But everytime I connect or disconnect using hyperterminal it switch my pic off?
Any idea why this happens?

Probe your MCLR pin when you disconnect the RS232 cable.
What's happen? Should go to GND for XYZ time. Place a pull-down resistor on pin 8 of your MAX232.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Hi Steve
Thx
I don't have instrumentation to do a probe on mclr.
Must I just put a pull down resistor on the max (What size 2k)?
|
let's say <10K should be enough. Also... be sure MCLR is tie to VCC with pull-up too.

a simple probe... use another PIC.
Code:Start: While PICInput=1 : wend HIGH LED pause 2000 LOW LED goto Start
