I do not understand how the Adruino supports diferent boards
I have an arduino MEGA board.
I need to use the same programming environment to program a BLUE PILL, which is a 3.3V system STM ARM uP. Will the same libraries work? Ie if I use an accelerometer or temperature chip, will the same library code work?
How do I add the Blue Pill board to my IDE environment so that I can choose to work with the BLUE PILL
Hi Clem,
You can find installation instructions for the Blue Pill here:
https://wiki.stm32duino.com/index.php?title=Installation
Libraries will not work universally between boards. You will probably be able to use the same libraries. If you need to be sure they will work you could use an Arduino equivalent of the Blue Pill.
Let me know if you have any questions!
Hi Stephen,
I don’t know where to go?
I have loaded the software and opened a simple blink example sketch and sometimes it downloads the compiled code othert times it gives the message: Couldn’t find the DFU device: [LEAF:0003]
The BLUE PULL green led blinks while downloading or trying to download and then does nothing!
Hi Clem,
In your sketches you will need to write to PB13 to control the LED. In your screenshots, you have 33 and PB1. As far as it not working sometimes, I’m not familiar with this board. Is there a reason that you are using this over other models?
I changed to PB13 and still no difference.
I selected BLUE PILL because of some YTube video I watched - I cannot remember the precise reason other than I wanted to use the STM32 ARM processor which I think is much better. Also simple small low cost system.
Regards
Hi Clem,
It could be that you need to hit the reset button before uploading? I’m not sure what else the problem might be. Sorry!
Hi Stephen,
Resetting did not help either.
Do you sell any board similar to the BLUE PILL which has an ARM STE23 processor - this is essential requirement.
Regards
Looks like there are a few flavours of STM32 boards in the wild
Are these able to be programmed via the Arduino IDE?
That might not always be the case; it would be best to check the product page and follow the links to guides. I don’t have a lot of experience with them; though they are popular enough in maker-circles
I tried to post on forum but could not work out how to encapsulate the code:
LIS3DH interface
It is unclear to me which pins of the sensor need to be connected Clk. D, CE to which pins of the MAXIM board in these examples and is this using I2C or SPI communication. ??? And do they use different pins for each type of communication? This is a simple question but I have no idea how to easily navigate the code to find out and how to change the pins for same function.
