STM32L476XX CAN functionality Support?

Posted on May 01, 2018 at 04:19I have purchased a https://os.mbed.com/platforms/ST-Nucleo-L476RG/ board for evaluating STM32L476XX MCU. However I am interested in the CAN functionality provided by the MCU and my question is do I need CAN transceiver...

Stack DMAable Memory Address While DMA Transfer

Posted on May 09, 2018 at 12:44Hi All,I am working on STM32H743 MCU's DMA.I was doing DMA transfer on the SRAM address space 0x30000000 (data transfer of 16K). I was visualizing a situation where i put this (0x30000000) address of the sram on the fu...

USB CDC receive buffer issue

Posted on June 01, 2018 at 08:13I'm using STM32F070RBT USB CDC device to communicate with PC. CDC channel is working fine except one issue. Looks like current channel has 63 character limit. i send 500 characters but i receive only 63 in buffer but ...

Error Handler: Write to external EEPROM

Posted on June 01, 2018 at 08:01When an error occurs, e.g. byte alignment, this might not be reproducible on the bench. It happens in the wild, when no debugging is possible.Therefore the idea, all these errors have a common error handler which does...

Best way to generate a fast square wave on PD2

Posted on May 31, 2018 at 22:48Hello, first of all pardon my ignorance, I'm a little new to STM32 development.  We are working on a project on an STM32F769, and my EE has asked me to generate a fairly fast (20mhz) clock output on a specific pin (PD2...

Resolved! Need help getting EXTI0 Wakeup interrupt (on STM32F042)

Posted on May 31, 2018 at 19:43I'm using CubeMX and don't see a way to enable the EXTI0 IRQ.  I'm assuming I need to have that interrupt enabled in order to use the PA0 pin as a wakeup pin.I've set that pin to SYS_WKUP1 in the pin configuration.  Wh...
