SPIClass

[leonhutton]

Hi, sorry for what I'm sure is a simple question: When I compile the dmd_demo sketch in Arduino, I get the following message:

_Arduino: 1.8.19 (Windows Store 1.8.57.0) (Windows 10), Board: "Generic STM32F1 series, Generic F103C8Tx, STM32CubeProgrammer (SWD), Enabled (generic 'Serial'), None, Low/Full Speed, Smallest (-Os default), None, Newlib Nano (default)"

dmd_demo:48:19: error: no matching function for call to 'SPIClass::SPIClass(int)'

Any ideas? I suspect something simple I am doing wrong...

Hi According to this:

ArduinoData\packages\STMicroelectronics

you use STM32 package from STMicro. The library is required STM32 package by Roger Clark, https://github.com/rogerclarkmelbourne/Arduino_STM32

Thankyou so much for your help. When I get my project going I will share the results!
