Hello. I'm currently implementing USB Drag and Drop Bitstream loader for FPGA using STM32F103CBTB and latest CubeIDE (1.10.0). The implementation uses STM32 in USB Mass storage class and virtual file system based on FAT12. The part of Drag and drop i...

I'm currently using the STM8L151F3 and implementing the SUMP open logic analyzer. In one part of my code involving with GPIO reading and send data to SPI1_DR. and to make a lots of the capture samples, I use the F-RAM as a external RAM for sampling m...

I solved the problem. I was able to add delay by using while loop decrement.uint32_t cnt = 0x1FFFF; // This seems to give me ~200ms delay at 48MHz clock STORAGE_Write_FS(){ // Stuffs before delay while(cnt--); // the delay // Stuffs after delay ...

Thanks for the reply. It's quite similar to my code but the answer still not so clear. I might try something else.

Oh great, thank you.

So, using "mov" will actually read the GPIO input (PortB in this case) and copy over to the SPI data register and the the SPI hardware do their own tx job. Is that correct ?

I did with both for l3g20 and lsm303dlhc .

Proper way to Delay / Pause in the middle of USB MSC transaction.

Can I use assembly command "mov" to move data from peripheral to peripheral ?
