Re: SerialUSB Not Working

On STM32, the USBSerial is mapped on Serial if the compile flag SERIAL_USB is provided, and it is provided for most of the boards variants.

Re: Seeed Arch Max

It is probably related to the fact that they change some pin layout for Mega compatibility as mentioned here :

Note : on newest board layout, the PB6/PDB7 are switched with the PD6/PD3 to get pins compatibility with Arduino Mega.

You should not copy the SPI library, it should stay at its original location.

Re: Compiling error STM32F407 SPI /ENC

You need to include SPI.h before UIPEthernet.h and have global instance "SPIClass SPI(1)" in you main sketch.

Re: $10 O-Scope revisited

For that, you should find peaks high and low, and then calculate the delta in time, you will then be able to display frequency.
Maybe you will need to average that value and refresh display of that value only once in while in case it is drifting too much, otherwise, it will be difficult to read.
