Arduino for STM32

Are you sure it's not the ILI9341 or Ethernet library that's at fault? I've had many problems with the Adafruit libs making assumptions about which SPI peripheral is being used and with what settings in the past. I'm currently using a MAX31856 & an SSD3106 without issue on 2 different SPI ports ...

Not STM32, but a Mojo V3 - Spartan 6 FPGA dev board landed today. https://lh3.googleusercontent.com/pw/ACtC-3e_MqxbAK0RubcxPyhkMH3Md1630_oTltztvIYb1R8aH_4wj-USVizMOMNMMii3kl6uB7KM6Qys5bTdOMrxUjyTEbtj9X3qs4Od6u_cXAec7acBAy-09LHOX0ywDXPLwW2vQqIgtMgKcQvbvMx-zXhfjQ=w1667-h1250-no?authuser=0 Just got to ...

Makefiles work just fine on windows. There've been many ways over the years to build a 'nix' like subsystem to allow make (and standard unix tools that make might call, ls, rm, etc etc), cygwin, msys, msys2, and even WSL. I uses MSYS2 without any issue.

Also some makefiles will make use of the GCC_PATH env variable - in this case you need to set the path to gcc but make sure you use unix / instead of windows \

There's no reason why a makefile shouldn't work in windows as long as you have a usable make in your path, and also the arm-none-eabi binaries in your path. I have msys2 installed which provides the make element - but this has to manually be added to your path, in my case it's c:\msys2\usr\bin As fo...

Fixed the 'acceleration' issue. basically the mouse data wasn't being cleared once processed, so the quadrature signals kept getting looped over. Setting them back to zero between samples fixes this (am disabling interrupts whilst the GPIO's are manipulated).

Will read that thanks Frederic.

Yup, but tbh it's easier to get the usb OTG host only & HID working in cube for now. So I have everything wired and the mouse works, after a fashion, on the Amiga - still need to get the scope on the signals because the mouse is behaving as if massively accelerated at the moment (big delta movem...

That works a charm, thanks!

Now to get the scope on the GPIO's to make sure it's behaving as expected.

Also need to work around the fact that the delays currently block simultaneous GPIO signal changes.

Luckily I always buy these in multiples, so have another board up and running now. Unfortunately the DWT code also results in no USB processing. It doesn't matter how short the delay is. The debugger seems to show the MC stuck in the while loop of the delay function. I'll double check my implementat...
