Hi the experts,
I'm not sure but i think that chip can realy help myself in my actual projet. i wanna get precisions about this chip.
In the technical datasheet i can read this :
ARM Cortex M0+ with 4KB flash and 1KB SRAM
I Want know if this chip is really able to :
For me i think that could be possible.
Did you get experience about this chip ?
Hi Jens,
I had already noted the fact of using the PIO0_4 for the UART TX .
Thank you for the warning about the risk of electrical overvoltage on the RS232 modem, but it will not be in my case of modem, but rather a module so I'm already protected against this risk. But I will watch anyway to monitor my electric tensions .
In my case PIO0_1 will be use to external interrupt signal capture.
If I understand what you say. Normally like i have no significant adjustment to make on the chip after her configuration. I concerve the freedom of using GPIO like i want?
If necessary I could reprogram the entire chip .
Also thank you for all this good details (explainations about electronic components).
I will keep you informed
I'm recommending the In-Circuit programming, because while developing, one will need to program the chip a couple of times, as it's rare to get everything 100% correct the first time. -But I'm not saying that's not the case for you; that's just how it is for me.
-But yes, you can use the GPIOs as you want, I just recommend that you keep the boot-pin pulled high, otherwise your program won't start up.
It might also be a good idea to keep the /RESET pulled up, at least until you change its configuration.
(some devices allow you to change the behaviour of the RESET pin permanently, I do not remember if this is the case for the LPC810).
Since it's a DIP, you can of course just program it in a breadboard or a ZIF socket and then insert it into the circuit.
My program will be very very simple so I will not have 50x modifications on the program.
And that's also what I had planned to do for the RESET, never be too careful .
And for the rest I always test on breadboard , it's easier
I fully agree with you on all points.
