New (LCP812)

Post by Renato » Fri Sep 04, 2015 1:57 pm

a) What specific model of LPC812/20 pin will be used ?
b) Is available a Basic Compiler for this chip family (without chip) ? I think it is possible with unique serial number linked.

SInce we started on the LPC812, the LPC824 has come out and we have been working on a version of that. It uses the LPC824M201JDH20J, though for most NXP parts the package type does not matter to the software (there are some exceptions).

This version we are looking to match it with the ESP8266 for a low end WiFi combination

As we do have a working firmware version for the 812, we will post that as a downloadable BASIC for purchase for $5 for non-commercial use. The 824 may become a board product, or may also be released as a downloadable BASIC.

We have the standard BASIC running in house now, but we want to integrate WiFi features for the release. We will get back to that in Oct, it is number 3 on the list right now.

If you don't want the net connectivity we could put something together before that.

Ok. I will buy the chips and after I'd like to purchase actual version of compiler.
If LPC824 module is available now, I'd like purchase one too.
Say me how to buy this two itens aren't in site yet.

I was asked about the schematic for this LPC824 board, attached below

1)You mentioned built-in WiFi ,does that imply some built in AT commands? ,[I had started to build an AT library.]
2) and a second serial port usage? My bad ,I see from the PDF that it uses a second port.
3) Would you recommend MQTT or CoAP for IoT message/info/control?? - any thoughts?
3) how much RAM will be available? MQTT uses a lot of http-type 'strings'
,
I apologize for so many ??s but 2016 is coming fast and I want to keep my momentum going.
(Have to watch out for long Christmas vacations!)

As I look into the mbed versions of CoAP and mqtt - I don't think that is your focus. You never mentioned IoT.
This looks/sounds like it will be a modified version of your ARMweb/ARM7 board - for the masses, as it were.
'
BTW- CoAP seems to have the smaller programs on mbed - in general., uses UDP vs the mqtt TCP.

The LPC824 code is ready, and will be available from the website in the next few days after I build a couple pages for the store.

Attached is an example of serving a simple web page over the ESP8266

esp8266 is the main page, you will need to change 2 lines to get access to your WiFi network.

The esp8266 should be running the latest firmware.

Re: New (LCP812) 824 pin assignments

Post by olzeke51 » Fri Jan 29, 2016 5:38 am

FWIW - I am translating Coridium's project onto the mbed-lpc824max board
AD2 & AD3 appear to be working, I needed to solder some headers for the other ADs;
hence the questions

'
I took a look at the webpages.bas program and am curious about the HTTP_AD subroutine.
You refer to AD2,3,4,5 -- looking at the data sheet and user manual the tssop20 uses
these ADC names - ADC2,3,9,10
corresponding to name(tssop-pin) P0-14(20);p0-23(1);p0-17(2);p0-13(3)
1) are your AD4,5 mapped internally (codewise) to ADC9,10 respectively??

*****
that leaves us with these digital pins
p0.1 p0.2 p0.3
p0.12 [BOOT isp]could be used after programming is done
p0.11 & p0.10 are for I2C or digital (with pullups needed for output)
******
2) p0.5 [RESETn] should be wired weak pullup/cap with switch to GND ??
*******
it appears tssop 18,17 VrefP,N need to be tied to +3.3 and GND
(manuals don't seem to indicate other assignments)
3) any input on this???
*****
p0.0 p0.4 debug/programming output/input for BasicTools
p0.8 p0.9 p0.15 are used for the es8266
?? 4) what version ESP are you using? -- yours has an 8pin header on it

Will this come to ' a product status' ? or is it being replaced with another device?
