Hello,
I made an adapter board for the BluePill to fit on the ramps 1.4.
I have some knowledge of micro controllers but i cannot figure out the pins values from your bord config:

#define X_MIN_PIN 0xDB//0xE5
#ifndef X_MAX_PIN
#define X_MAX_PIN 0xBE//0xE4

Blue pill pin-outs are noted as PA-15 PB0-15 and so on.
Where did you get thees values in hex a?
Also how flexible is your port?
Does it support hardware SPI and I2C?

My configuration is as follows:
-STM32F103C8(CB) <STM32F407VET6 - Future upgrade>
-Modified RAMPS
-TMC2130 (SPI mode)
-I2C Display (4x20) 2004
-SPI Card Reader module
-Single analog pin - 5 button Navigation keys
-esp8266(future add-on, for connection over WiFi)

Given that this is an older 1.1.9 release, I am not sure if I'll get any feedback but I thought it is worth a shot!

I am reviving an older machine running custom board and custom 1.1.8 firmware. I would like to recompile for 1.1.9 and
this repo shows the most potential! However part of their customization to their marlin is enabling TX_BUFFER_SIZE 128 instead of 0.

The printer heavily uses serial port communication with Marlin to issue commands. Once I made that change I could no longer compile the project. Thanks!

Hello I have an STM32F103 3D printer. I want to use the board for other porpuses. When I need to reprogram the board, I dont want to configure again. Can I just download the program in the board and just upload that program after I completed the other works? If it is how?
Thank you.

@hackaday3D Can I suggest that you port Marlin firmware to run the new STM32MP1 MPU series?
https://blog.st.com/stm32mp1-mpu-stm32mp157a-ev1-stm32mp157c-dk2/

I am only an end-user / technology enthusiast myself and I do not actually know if anyone else is already working on a 3D-printer controller board based on the new STM32MP1 MPU series or not, however, I read that STMicroelectronics claims STM32MP1 architecture enables developers to use the same software as STM32 MCU series, and theoretically, with the STM32MP1 MPU series you could run both Marlin and OctoPrint or similar Linux distrobution on the same board.

For technical specification summery checkout:

STM32MP157A-DK1 and STM32MP157C-DK2 Discovery kits are $99 with LCD or $69 without

STM32MP157A-EV1 Evaluation kit for PCB engineers does have a steeper price at $399

First read about this MCU/MPU in the release news about PanGu board from I2Som

How do you set the BAUD rate?
I believe my board is set for 115200 not 250000
Thanks!

Currently I have a code version 1.1.9
I want to convert it to STM32F103RCT6 can I use your configuration program?
and i need pin mapping for RCT6 same as your VCT6
Can you help me convert it to RCT6?

Can I print via USB?

just test to compile marlin_stm32 with ARDUINO ide1.8.5 & stm32duino core support，but with some error in compile，so I want know which stm32core for arduino did you use？

Excuse me, I Cannot open link, How to download Compile Tool? Thank you
