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,I could use some help getting started with SPI5 (limited feature set). I want to operate as SPI master and send a single byte. I want to control SS manually as ordinary GPIO out.I've enabled the peripheral clock, and I can see in the debugger that...
Hey, I am trying to send 20 messages over FDCAN using the G0B1RE Nucleo board. The problem is that only a few messages arrive (~12 most of the time), the messages have wrong data and sometimes it crashes the FDCAN-Module. When it crashes the HAL_FDCA...
Posted on September 01, 2017 at 06:37Hi, I have an STM32F746G-DISCO board and I am running some DAC examples. I need physical access to PA4 (DAC_OUT1) and PA5 (DAC_OUT2) so I can display them both on the oscilloscope. The DAC example says you can a...
I am using STM32CubeIDE 1.15.0, writing code in C, including some assembler code, for the STM32G431.According to ST's programming manual PM0214 in Section 3.5.1, I should be allowed to useadc r0, r1, lsl #1However, gcc barfs (I am using standard gnu1...
Hi all,I am in the process of bringing up a prototype board with a STM32L4R7ZIT6 up. I'm using one DAC channel via the opamp. This is working all right, until I designate the default output of the DAC to another function e.g. dig output. The DAC is c...
- STM32G0B0RE Our controller was running fairly well but on occasion we were seeing the windowed watchdog trip(The IWDDGRSTF flag set on reboot.) We were not sure whether this was a too short or too long trip so decided to extend the window wider...
HiThe DataSheet doesn"t give the input impedance of internal OP-AMP in follower mode.The only value is for PGA mode.There is a similar question about STM32U575 on the forum but not answer... Thanks for your help have a good day. Aurélien
Hi all,A USB device should pull up DP when it detects VBUS power only. This is described in the USB standards and ST AN4879 factsheet. Question 1. Is there any other (smarter) way with the STM32L072 than to monitor VBUS power on a GPIO yourself (via ...
I have buy STM32F407VET6 discovery in the past, and for some reason i need some more. been looking on the local marketlist on my country most don't sell it anymore, and my past store still hasn't restocking it yet, and i'm found similar board with sa...
