Arduino for STM32

It won't work with F103 as RTC does not have calendar and it does not store time in unix format.
It only stores time when it was set and counts seconds since then.

Thanks for your reply man!!!

Hey all !!!

I hope y'all are doing well... I'm really sorry, but I need help on a problem with reading/writing character/string on STM32's emulated EEPROM.

I'm using STM32F103C6/C8 with 128 kb internal flash.

I used this tutorial for preliminary setup : "https://www.instructables.com/Getting-S ...

Hey there,

I'm not an expert, but with my previous experience with serial communication on STM32, I guess I can give a clarification.
You have received reversed question mark(I too received those buddies...), which means, no data is received.

The problem is(I guess), you are using Serial1 to both ...

Hey all !!!

I hope y'all are doing well...

I'm using Setup : Digital weighing scale using Renesas chip connected to one channel of Max232, another channel of Max232 connected to STM32. STM32 is connected to PC via FTDI232 serial to USB converter. A push button is attached to STM32, to facilitate ...

I thank all, for helping a lot in my problem, especially, Mr. stevestrong .

Now I'm trying to write the weight data to STM32's emulated EEPROM. Before that, I was testing a test program influenced by inbuilt EEPROM example to write and read data. But while compiling, I get some error. Link to that ...

Long Long Live Mr. stevestrong

Thanks a lot sir... It's finally working... :D :D :D
I was working out on that issue.. But you solved the issue quickly... :)
Because of you only, I am completing my first ever Arduino-STM32 project.
Thanks a lot for being kind, gentle to this novice kid.
You're ...

Long live stevestrong

I changed


#define NR_BYTES 7


to


#define NR_BYTES 10


and


if ((m-rxTime)>50)


to


if ((m-rxTime)>80)


I've got output like :

000.120

000.120

000.120

000.120

000.120

But the output starts printing immediately after uploading, and doesn't respond to ...

Code: Select all

inBytes[inCnt++] = Serial.read();

should be

Code: Select all

inBytes[inCnt++] = Serial2.read();

I'm sorry for that, Sir.. childish mistake..

The misstake is that you tweaked my code incorrectly.
inBytes[inCnt++] = Serial.read();
should be
inBytes[inCnt++] = Serial2.read();

I added LED blink by data reception:
#define NR_BYTES 10
uint8 inBytes[10], inCnt, dataIn;
uint32 rxTime;
void loop()
{
uint32 m = millis();
if ((m-rxTime ...
