I’ve bought a B-G431-ESC and trying to program the board using arduino but i get this error while trying to upload a sample code in the simplefoc libraby

If you are using Arduino, are you sure that you selected the board as the B-G431B-ESC1?
The board variant has the specific defines for the things you are missing here.

KAVIN_G · March 25, 2024, 3:31pm

no i selected stm32g series can you help me with a reference link on how to connect the B-G431B-ESC1 with AS5600 ? also i couldn’t read anything from the serial monitor even it is just a simple “Hi” serialprint

There should be a board entry for the ESC1 in particular, it is part of the stm32duino variants. You need to select that from the boards list before doing anything else.

i tired this code and the code got uploaded and i got a success message and i got some serial readings in the serial monitor but motor is not rotating it just pulses also a big red led near the stlink ic is glowing

Tried to just test the example sketch of the as5600 in the utils folder but i’m not getting any response from the serial montior but the code is uploaded . I’ll say what are the things i’ve done
1.Opened a new b-g431-esc out of the cover connected the i2C wire as per the given photo below

2. opened the platformio and created a new project with discovery b-g431-esc1 as per @Owen_Williams tutorial selected and added the neccessary build flags and libdeps in the platformio file .
3.opened a example as5600 and uploaded it uploaded sucessfully but i’m not reading anything from the searial monitor it is just empty(Also a big right red led is always on)

i’m just a newbie, Please anybody help any kind of help or suggestion would be appreciated
