SPI TxRx callback processing

I have a Pi that sends data to the MCU via SPI. I have the SPI running in DMA circular buffer mode on the MCU. In the TxRx callback, the data from the Pi is processed, and then the motors are turned ON/OFF, etc. This works, however, each time the Pi ...

Resolved! Is it possible to interrupt another interrupt?

This is a fairly high-level question... but just wondering whether the NVIC system is capable of interrupting an interrupt when one of higher priority comes in? Can someone point me to information on this?Thanks,Doug Burrell

Resolved! Supplying voltage on VBAT pin on STM32F469I-DISCO

Hi everyone, I am currently working on a project working on a STM32F469I-DISCO. I would like to be able to use the embedded RTC as well as the backup SRAM. I have seen on the schematic that the VBAT pin is tied up to the 3.3V. Is there a way to still...

Discrepancy chip marking vs product/chip ID ? My chip marked STM32F100V8T6B give a productID 0x414, while I expected 0x420. Have I received a batch of chips with an incorrect marking?

According to AN2606 rev 14, pid 0x414 mean high-density device, pid 0x420 mean medium-density device. We just bought 500 STM32F100V8T6B. They are deployed in an existing modular product that programs the uC in-situ. The program relies on the PID to ...
