Arduino for STM32

ag123

I already made my own firmware via STM32F103RDT6.

I confirmed that uploading the STM32duino Bootloader through the Arduino IDE is working.

Now I want to upload via QTCreator rather than Arduino IDE.

While looking for a possible way, I found the Maple_upload.bat file, and it seems that I ...

I want to implement maple upload in a custom GUI.

I searched for this and that, and found that the following was output in the Arduino terminal.

C:\Users\NEO_IOS_107\AppData\Local\Arduino15\packages\stm32duino\tools\stm32tools\2022.9.26/win/maple_upload.bat COM8 2 1EAF:0003 C:\Users\NEO_IOS_107 ...

HIGH rises only when firmware update is in progress
Do you have a pin?

If there is such a pin, I would like to connect it.

hello experts

I have a question about updating the firmware, so I left a question.

I want to proceed with the current firmware update through USART.
I would like to make the BOOT0 pin HIGH only when updating firmware and lower BOOT0 to LOW otherwise.

I don't want to set this as a physical jumper ...

Following your advice, I tried to build a new bootloader.

I tried to assign functions to pins by selecting STM32F103RDT6 through STM32CudeMX, but I could only select USART3 for PC10 and 11 pins.
(I want to give USART1 function to PC10,11.)

Is it different from the way you advised?

I made a PCB with the STM32F103RDT6 mounted on it.
Some of the designed circuits are as follows.
//
USB DP, DM : NC (PA11, PA12)
FTDI : USART3 (tx : PC10, rx : PC11)
RS232 : USART1 (tx : PA9, rx : PA10)
BOOT0,1 : LOW fix (NC)
ST-LINK : SWDIO, SWCLK, NRST (PA13, PA14, NRST)
//

Because of the above ...

@fpiSTM

I understand what you mean

Thank you very much for your reply. It was a big help.

@fpiSTM

Thank you for answer.

So, is there any way to use USART3 pins (PC10,11) as USART1?
Please tell me everything except how to jump on the circuit.

hello expert

I'm currently using a STM32F103RDT6 and I'm developing it via Arduino IDE.

Among the upload methods of Arduino IDE, I am uploading firmware through ST-LINK, but it is cumbersome to continuously use ST-LINK due to the structure of the hardware I am making. And modifying this hardware ...

Board : Stm32f103c8t6 (Roger's Core)

I want to use sleep mode on the board.
So I tried to use the STM32duino LOW POWER library,
Because it is Roger's Core, stm32_def.h compilation error occurs.

How does Roger's Core use sleep mode?

Can you provide a relevant register datasheet or example code?
