Arduino for STM32

geocheats2

based on the schematics
https://github.com/FYSETC/FYSETC-SPIDER/blob/main/hardware/Spider%20V2.2%20SCH.pdf
it uses the on-chip usb and the boot0 pin is on a header.
so all you need is set boot0
reset and you can upload firmware using the on-chip usb over DFU
no additional boot loader is needed ...

Hello to everyone

I bought this board https://github.com/FYSETC/FYSETC-SPIDER v2.2 in order to use it in a custom application and not as a 3D printer controller

In my application i would like to have it connected to a PC over usb and get the data of the usb cdc serial but i can't seem to be able ...

RTD value: 8545
Ratio = 0.26077271
Resistance = 112.13226318
Temperature = 31.15

It worked correctly over SW-SPI, i will try to fix HW-SPI but for now its not critical

THANKS for all the information

Code: Select all

Ratio = 0.51989746
Resistance = 223.55590820
Temperature = 332.47
Fault 0x1

It still has some fault but at least i have data out of the SDO pin

We found an issue using Adafruit libraries. it uses int8_t as type for pin but STM32 can have pin higher than 127 or alias pin PYn higher than 127.
This is the case here. Try with Dx or x number instead of PYn.

PA4 is defined as PIN_A22 as it has analog capabilities so higher than 127. It's ...

I have a problem, i am guessing at the framework level.

I got a Nucleo-144 (H743ZI2) and some RTD readers featuring MAX31865 over SPI.

I spend 2 days trying to debug why the SPI-DO whouldn't transmit any data.

If i am correct MISO(DO) should be kept low and rise on data transmition?
