New PIC32 Series PIC32MZ2048ECH144

[bpislife]

It has now been 13 months since the release. Any updates?

Hi,

I am afraid that I do not have any news yet, except that we are working on it.
Thank you for your patience.

Best regards,

hi,
will libraries be fix ? there are few ( or moor ) bugs in libraries . for example on str and memory types etc.
and the ethernet librarie. it would be great to know that .

Hi,

Please, can you be more specific? On which bugs you refer?

We are doing our best to correct every problem and to implement every improvement (which is possible to implement)
which are users suggest to improve our compilers and software.

Best regards,
Marina

hi,
thank for answering ! or attention, is better.
i have mentioned a few before and i got no answers. but i have a very very bigger question for me and everyone in mk.
is it possible some day you support your compiler like mplab from microchip for languages ? specially for assembly and c++ full ? and i say is this possible ? and if yes ; please say when ? like 6 mounts ? 1 year ? 2 ...
and if it is not, please be kind ( warm-hearted )and tell us why, in technical terms.
thanks.
best regards, Josef

Hi,

Our compiler allows embedding assembly in the source code by means of the asm statement - asm block
and at this moment we do not have in our plans developing full assemble compiler.

Regarding C++ compiler, on our forum you can find many topics related with this question,
and also, answers of some of our users and some of my colleagues.

For example, please, take a look at this forum topic:
http://www.mikroe.com/forum/viewtopic.php?f=166&t=55311

Best regards,

How about now? Any update on when the PIC32 C compiler will be updated? We are now at a 16 month release.

[mefleming55]

The PIC32MZ is an amazing machine, and we love your compilers, please help us plan by some indication of when MicroC will support the PIC32Mz?

6 Months?
12 Months?
24 Months?

We're dying here

Hi,

At this moment our software developers are working on new PIC32 compilers release.

Thank you for your understanding and your patience.

sorry, i forgot at that time, this is a problem itself ! its a very big site and users some times forget to answer, there should be a message to alarm them when the post was answered.
for that Ethernet lib, micro was hanging alot, and the password was unstable and easily hacked. after that time when i was checking again after few month i learned the java source code and the other source code that you put in the library, ( you did not check the code and just copy-past it from the source web ) had several errors. i was able to fix it after few days, unfortunately i don't remember what was it. you should have some people for that, because im not a java and php programmer and i got lucky !
------------------------
in another matter, there is a very bad glitch in your registering codes, specially in ADC. i was working on a smps with 30f2020 and i wanted the fast speed of ADC. i did set the registries, but the max speed that i could get was 14k sample, instead of 500ks ! and now i have to do it with pic32mx460. i hope it works this time with fifo . i cant use you ADC_READ , AND i dont know why ?!
is this enough for you to start checking your libs ?

Hi,

Thank you very much for more detail explanation, we really appreciate it.
Our software developers will certainly consider to revise Ethernet library (and also add some more detailed documentation).

Regarding ADC library: it is a very simple library, but of course it is not excluded that an error can occurs.

Like I mentioned in one of my previous answer, we are doing our best to correct every problem and to implement every improvement which is possible to implement in our compiler libraries.
It is hard to reproduce the error if I do not have the same hardware which you use (and code which you tested),
so we usually ask our users to send us some small project which represent problem which they have so we can try to find source of the problem as quickly as possible.

Of course, we are testing our libraries, but unfortunately it is not possible to test them with every supported MCU and also we are not able to predict every situation. Because of that we really appreciate any assistance which we receive from our users.

Best regards,
Marina
