Hi!
I have an STM32F3 discovery board, with an STM32f303VC chip ot, and trying to make USB working. I haven't found a USB library for that. Can somebody help me, lease?
Thanks, and sorry about my english.

I have tried a lot to get any of the four possible 16 quad encoder counters (Tim2 -5) running, with no success. Can anyone have a suggestion? See my sample code below.

I use STM32F373 with mikroC for ARM.
I need to use SDADC in STM32F373.
but I can not work it.
please help...OTL

Is there a Pascal example of the proper register setting for a 168 MHz closk of the MCU card with STM32F407VGT6. And how to setup tmer 2 to 5 for quadrature encoder readout for this device?
Thanks

hi, evrybody.,
I use program "MikroPascal for 8051" but I do not know how to use the command:
EEPROM_Write
EEPROM_Read
i'd like to write some data to eeprom (24c04)
and read it
pls, help me
