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...


Resolved! STM32L4 current consumption is more than expected.

I am working with a NUCLEO_l452RE, temperature 25°C, 1.8V, and I am measuring current on JP6, so I tried to reproduce: I set up MSI@1Mhz, I got 280uA, much more than 100uA which I was expecting.Later with MSI@24Mhz, I got 3.24 mA, 135uA/MHz, closer t...

STM32L552, relocate IRQ Vector Table

We are porting code from a STM32L4P5, where we relocate the IRQ VEctor Table with  memcpy(g_RamVectorTable, g_pfnVectors, sizeof(g_RamVectorTable)); __HAL_SYSCFG_REMAPMEMORY_SRAM();    // not implemented on STM32L5xxthat works fine, but as commented ...

High frequency DAC signal generation

Hi, i am working on signal wave generation on the STM32L053 Discovery kit. I'd like to see the maximum frequency of signal generation (a sinus with 100 samples using DMA). But the problem is : i cannot reach over ~20kHz, which is not even in the ultr...

STM32G031F6P UART TX DMA Problem.

Hi guys.I am using STM32G031F6P MCU and i want to use UART TX with DMA in slave mode. But it is not working. RS485 line is always busy. I am using RS485 transceiver (SN65HVD37DR). If i use normal (not DMA) transmit mode, it is working. Code and cubem...

How to config FT231XS for STML451 on my board

I have a FT231XS on my board and a STML451. I would like to communicate over Uart to STM. So i need the FT231XS as USB to UART converter. My software works with NUCLEOL425RE, so when i send some strings over a Serial Port i can receive it immediately...
