At present, the vc environment of raw-os + fatfs has been built and can run normally. The vc environment of sqlite can also run, but it is based on the windows file system. Now we need to strip sqlite...
As shown in the picture, I made a function generator to generate a sine wave with a bias of 0 and an amplitude of 2V.
Two resistors are added externally to provide a 10V bias.
I thought that adding th...
