New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

CubeMX not generating the correct MX_GPIO_init()

Hello, I am working with cubeMX and trying to configure a pin to output mode. The MX_GPIO_init()  is not generated correctly, there is just clock enabling of the bus connected to the GPIO ports without the configuration of the pins. I am using CubeMX...

I have an issue with the HAL_DMA_TransmitReceive() function. I am using full-duplex SPI communication between STM32F030R8T6 as master, and Nucleo-C031C6 as slave. I am only using DMA on the master side. My DMA clock is at 40MHz, SPI clock is at 10MHz.

The problem is I can successfully transmit-receive up to 4 bytes of data. Above that amount, anomalies happen. I need to transfer 20 bytes of data in both directions. Does this have anything to do with RXFIFO and TXFIFO buffers being 4 bytes, or is i...
