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 there,I'm designing an application with an STM32L412K8 and I don't use ADC, OPAMP or COMP. The datasheet (DS12469) says:VDDA shall be 0 to 3.6 V if ADC, OPAMP, COMP is not used (general operating conditions table 21).When the functions supplied by...
Hi,We are using STM32F746ZET6.we have to calculate input frequency on 5 pins from 40khz to 0.01hz.currently we are using 50 micro seconds timer and at every timer interrupt we are processing frequency calculation based on the polling of the pin stat...
Hi all, I've recently been teached about how to manage streamed data in this case for managing commands, then my code is like the following explanation: I've programmed the uart2 to receive the streamed data byte to byte and I've been storing it in a...
How do I obtain one? Cube isn't helpful -- this isn't a filter parameter. I need an MCU with built-in backup battery domain for the RTC. I don't want to build anything external and the design must not be capable of powering up the core from the batte...
I have an 8 bit(Parallel data) ADC output of frequency 50MHz. At this frequency, I tried to store 1400 bytes of data on STM32F446RE but failed. According to its specification sheet, GPIO ports can support till 180MHz. Could you tell what is the rea...
After the firmware is up and running, I am trying to put the SDRAM in self-refresh mode. We are using FreeRTOS. In order to put SDRAM into self-refresh mode, I write 0x4480D to FMC_SDCMR register. I am using IAR debugger, and I execute the statement...
Hello, I am very new to STM32 MCUs and hoping someone can explain to me the HardFault_Handler and possible reasons why my code is jumping to here? If there is a good resource which discusses this, that would also be very useful but I haven't been abl...
Need 10 samples for a new product prototype. PCBs on the way now. None available in distribution. Can you help?Thanks - Duncan
Hello,I want to use MDMA on STM32H7 to copy data from ADC to DTCM RAM. But it is not clear to me how to set it up . From ref manual I asume that there is a connection with "standard DMA" DMA1 or DMA2, maybe I have to set up a channel there to, but th...
