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...

GPIO output voltage level in stm32g4

I want to know the ouput level of the pin PA3 wich has a structure as TT_a (3.6 V tolerant I/O)the table provided in the datasheet is a bit tricky to understand. Which are the row that I should consider for the PA3 pin? Cmos or TTL or the others?

Resolved! STM32H725 NVIC priority and subprioririty

Hi!I try to set IRQ priority to 3 and subpriority to 2.HAL_NVIC_SetPriority(EXTI9_5_IRQn, 3, 2);I suppose that correspond NVIC IPR [23] now is 0x32. But it is 0x30. I read AIRCR PRIGROUP (it is 3).uint32_t PriorityGroup = NVIC_GetPriorityGrouping();A...

ESP-PSRAM64H and STM32H743 QSPI mode

Hi,Is there any one success with ESP-PSRAM64H in memory mapped mode?We are able to read ID (0x9F) in spi mode. But when we read/write, it return 0xFF. We don't see EnableWrite command, does this chip has EnableWrite command?We also wanted to use thi...

I need to send 2 bytes over the I²c bus with a STM32L432 as slave and a Raspberry Pi as master. But the clockpulse of the SCL is to wide.

In the code below I send 2 bytes with my STM32 (I've chosen a number higher then 255 (340) so it needs to send the data in 2 bytes) but on the scope I cant find this data. I guess it's because of the wide clockpulse and the Rpi expect an ACK. Instead...

Using flash algorithm from F103 for F405

Hi,I am trying to use a flash write and read module written for the STM32F103 on an STM32F405.However the F103 deals with pages and subpages. Some algorithms depend on subpage size. The F405 has sectors, which I guess are the equivalent to pages, but...

Resolved! Shutdown mode for RTC

Hello, I'm using the demoboard B-U585I-IOT02A with a STM32U5 microcontroller. Today, I'm using a RTC with an external battery placed before VBAT. But in order to reduce current consumption, I'm currently working on using shutdown mode in order to jus...
