Compilation leads to error: use of undeclared identifier 'dwBytesRead'

[2ni]

Hi
Thanks for providing this code!
I tried to compile it on my mac:

git clone https://github.com/Polarisru/updiprog
cd updiprog; mkdir build; cd build
cmake
make

-> this leads to:
updiprog/com.c:201:10: error: use of undeclared identifier 'dwBytesRead'

Maybe you know why?

Hello, this should be a problem with a Mac version probably. Nobody has built it yet and I see some problems in the UART processing code: I have only MINGW32 and __linux defines there, so I guess Mac doesn't know what to do. Unfortunately I don't have a Mac, so I can't find a solution for this issue :( You have to write some Mac code for writing and reading a serial port to make it possible.

Hey, I found a solution, but I can't make a pull. For macs, you can use the same as for __linux.
So you can just replace all
#ifdef __linux
with
if defined(__APPLE__) || defined(__linux)

I also like to control RTS and DTR pins. Would it be possible to add a flag to set/clear rts and dts?
The code to eg clear RTS and set DTR would be as follows in com.c COM_Open() just after the open() command:

#include <sys/ioctl.h>
...

int RTS_flag;
RTS_flag = TIOCM_RTS;
ioctl(fd, TIOCMBIC, &RTS_flag); // TIOCMBIS: set, TIOCMBIC: clear
int DTR_flag;
DTR_flag = TIOCM_DTR;
ioctl(fd, TIOCMBIS, &DTR_flag); // TIOCMBIS: set, TIOCMBIC: clear

Can you make a pull request?
Yes, I can add these pins, what do you want to do with them? I am asking because of flags, how should I name them?

[2ni]

ok, will do. I created a programmer which can switch between uart and updi on the same serial terminal connected to the computer. I use the DTR line to control if I use uart or updi on the mcu. For this reason I need to clear DTR and set RTS.
I was thinking of 2 additional parameters to set or clear dtr and rts (one for each). (-d and -r are already taken :-()

could it be that I have no permissions to push?

I have sent you an invite, it will be probably possible to push to the repository directly after accepting it

Thanks! Do you think I can re-use the argument onDTR to set DTR and clear RTS? I would also do a pull for it then
