That has nothing to do with the topic of this thread: "How to change c++ code into NORDIC nRF52832"

You need to start a new thread for a different topic!

But, as noted, it has nothing to do with Nordic.

gain: Are you referring to the original code - the subject of this thread - or Nguyen Hoan Hoang's code?

For the latter, did you see the instructions on GitHub:

What project?

As it's a 3rd-party project, that's not really a question for Nordic.

The SES manual is here:

Sorry, the picture is unclear - I can't see what the message says.

Well, you can - but there'll be an amount of work to it!

As has already been pointed out to gain, it's not about nRF - it's all just standard language stuff.

Thank you very much Nguyen Hoan Hoang

it is very helpful to me

and thanks to Nordic Dev Zone

Using C syntax (ie no x.method()) however it's in a C++ method definition so they are most probably instance members or methods of the class. eg send_col() is just called with no object instance, however it's an instance method of the class (I just googled for the code) so that's implicitly this->send_col(), the this-> is inferred. So you can't flatten the code, you need the object reference.

But it's only accessing those things using standard 'C' syntax....

Of course, any & all external references would have to be satisfied.

Probably not quite as it uses variables like cgram and functions such as chip_byte_address() which I assume are member variables and methods, unless they are globals which is not so likely.

However if he defines HT1632_LedMatrix_putChar() as you have above but with an initial HT1632_LedMatrix pointer, as extern "C", and then calls through the pointer it effectively renames the function into something callable from C, you just drag the pointer about.

However I'm not sure I understand the original question at all and the answer 'no changes are required' is the right one.

Nguyen Hoan Hoang — Thu, 30 May 2019 12:30:31 GMT

No changes are required. It all depends on the compiler not the processor. You can use C++ with nRF no problem. See this library https://github.com/I-SYST/EHAL. It's C++ fully object oriented. it actually have code for the HT1632.

RE: How to change c++ code into NORDIC nRF52832

awneil — Thu, 30 May 2019 10:45:35 GMT

Exactly the same as would be required to convert any other C++ code to C - the languages are standard; not specific to Nordic.

But the function seems to be only using 'C' syntax anyhow - apart from the initial

uint8_t HT1632_LedMatrix::putChar(int x, int y, char c) {

So you could start by just changing that to a standard 'C' function signature; eg,

uint8_t HT1632_LedMatrix_putChar(int x, int y, char c) {

for using above code in nrf52832 what are the changes required ?

Not sure what you're actually asking here.
