First deal with STM 32 (by Ahmad sakr)
Dear sir
I have just received my blue Bill but as I'm newbie for stm32f1. What is the program which will be needed for burning hex file? Is it like AVR in LDMICRO after finishing program combile and burn hex file? What is the procedure for first deal with STM 32 in both hardware (schematic diagram) and software in LDMICRO? Thanks for your great work and support Best regards

Hi Ahmad
To program your Bluepill board with hex file you need a St-Link-v2 programmer or a low cost clone, as on this picture. (A few $ only) Have you got it ? Then you have to configure flashMCU.bat to - compile your ladder program with STM32F1 libraries for ldmicro - send hex file to the blupill with St-link software I'll help you if need be. Best regards José

Dear José
Thanks for your reply and great support Yes I have a at link v2 programmer like the one in the picture. I will create ladder in LDMICRO (simple one input contact to enable or disable an output coil) . And select microcontroller as arm STM 32 F1 from setting menu Then from combile menu will select combile Then from the programmer program burn the hex file Is this steps true Best regards Thanks very much

OK
Use if you can ldmicro version 5.3.1.0 rather than 5.4, because I haven't tested yet the last one. In your flashMCU.bat (in the same directory as ldmicro.exe) edit the :ARMGCC section and modify both variables GCC_PATH and STL_PATH to point to the installation directories of these two softwares : SET GCC_PATH=C:\Program Files\EmIDE\emIDE V2.20\arm SET STL_PATH=C:\Program Files\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK Utility The first one points to your ARM Compiler (Arm-Gcc directory) The other one points to your ST-Link command line Utility (st-link_cli.exe) Then compile your ladder for ARM-Gcc and call FlashMCU.bat from ldmicro menu. It should generate your hex file in bin sudfolder. PS: Read HowTo-Arm.txt in Libraries_for more details. Let us know if it works as expected. José

Dear José
Thanks for your reply I did it.it working fine. What about the boot jumber ? Will I make it like the picture you attached? I'm very glad to you.thank you very much Best regards

Sorry sir
Should I make MCU crystal frequency 72000000 in LDMICRO MCU parameters menu.? Thanks very much Best regards

Hi
You must set MCU frequency at 72,000000 MHz On my board, Boot0 is 1 and Boot1 is 0, but I don't remember why... José

Dear José
Could you please make a summary for blue pill arm 32 interfacing like this one http://cq.cx/interface.pl As it's different than AVR 3.3v not 5 v Thanks for your great support Best regards

Hi Ahmad
Unfortunately, I don't have time to write such a document, which is a bit far away from ldmicro. Here are some information and testing ladders for bluepill ; that's all what I can do. BR José

A bit more about pin assignment for Bluepill:
PA0-PA3 Free / ADC / USART2 PA4-PA7 Free / ADC / SPI1 PA8-PA12 Free / USART1 / PWM1 PA13-PA15 JTAG PB0-PB1 Free / ADC PB2 Jumper BOOT1 (BOOT0 is independant) PB3-PB4 JTAG PB5-PB7 Free / I2C1 PB8-PB9 Free PB10-PB11 Free / I2C2 / USART3 PB12-PB15 Free / SPI2 PC13 Green LED on Blupill (reverse logic) PC14-15 Free

Thank you sir
Could you please send the circuit schematic for every tested ladder program in the previous attachment (bluepill.zip) Thanks for your great support Best regards

Dear José
Is it true that bluepill can be powered by 5v or 3.3v? Pins pb13,pb14 can work as input or output at 5v or can be 3.3v also.is that true? But pins pb1 ,pb1 only deal with 3.3v ? Is that true as I understand? Thanks for your great support Best regards

Bluepill MCU works at 3,3 V. It will be powered by your St-link-v2 dongle, but don't expect much current. Digital outputs are at 3,3 V ; some inputs are said to support 5 V but at your own risk. If your affraid with powering inputs at 5 V, put 2 basic diodes in serial with your input to make voltage go down to 3,7 V: 3,3 V Input on MCU ----|<|---|<|---- 0 / 5V source | R | GND and add an external pull-down resistor (10 k) directly on the input. It should work...

hello Ahmad sakr.
Could you please put together a video tutorial on how to set up flashMCU and generate hexadecimal to write to STM? Basic step by step contact with a single coil, from pin addressing, compile write to STM. Grateful if possible.
