Re: Arduino bootloader development
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. you...

Arduino bootloader development
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 to ...

Re: SPI Bus wont work on Nucleo
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 /*************************************************** This is a library for the Adafruit PT100/P1000 ...

Re: SPI Bus wont work on Nucleo
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 digital...

SPI Bus wont work on Nucleo
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? Datasheet Flow B...
