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...
Hi folks,I'm facing a strange issue with my PWM which changes polarity every once in a while and I think the issue is due to the way I'm generating a PWM while using up and down counter mode. I have two identical configured but independent HRTIM coun...
Hello,I'm using an stm32f411ce in an application that includes an external interrupt, a uart DMA TF interrupt and a systick interrupt. with the external interrupt in the highest priority and the systick in the lowest respectively. The code runs for a...
I received CAN data successfully but when I send CAN data, there was some error shown. My Code is,https://drive.google.com/file/d/1g67-LwlqfaCf8QpeAptYLtTEByo_R9nr/view?usp=sharing
As per datasheet of stm32f769ni, LSI frequency is temperature dependent. So watchdog reset timer can be affected as the LSI frequency varies. Is there any method to configure IWDG reload timer with specific interval of time with updated LSI frequenc...
ps: I need to know it steps by step because of my limited knowledge.
I was wondering why when I am setting up my board in CubeMX that some of the peripherals are initialized automatically? Like for example the Green LED or T_NRST set up in GPIO?Is there a way to start with nothing initialized? One would think that ch...
Hii'm testing Thread_Coap_MultiBoard example and it works well as readme.txt explained.but it's on m4(=cpu1) layer.i have question for m0 behavior about mesh network. i get a m0(=cpu0)'s serial log below```[0002283462] [MLE] [INFO]-MLE-----: Rece...
I am currently trying to read my temperate Sensor and Vrefint channel to get the system's temperature and system power voltage. I am measuring 4 other ADCs (11, 12, 13, 15). They are all returning values within an expected range. My expectation is:Th...
Hello,I am in the process of designing a product which is based on the STM32-H7 and requires more RAM, somewhere in the 2-digit MB range (8 or 16 MB should do).As I understand, I have several options:Using SD-RAM with the Flexible Memory Controller (...
Hi,I work with a development team that is developing a product that has a STM32L4S9 MCU and a IS66WVH8M8ALL-100 HyperBus PSRAM.Recently, we found in the STM32L4 Errata that actually this MCU does not support PSRAM. We noticed that the self-refresh wa...
