Hello everyone,I’m working on an STM32H7S3L8H6H with two XSPI interfaces:XSPI1 (Quad-SPI) connects to an external PSRAM. XSPI2 (Octo-SPI) drives an external NOR flash, from which my application code executes directly.In my bootloader I configure both...
Hello, is there any changes about MFG label of the STM32 MCUs products ?we receive the new DC product, and found the "Assembled in: Site" was miss ,which shall be show on the second line of the label, pls check below photos , is it correct ?if yes ...
Hello,I am working on creating a timer function using the timer peripheral of the STM32H743II, with a timer range from 1 second to 3600 seconds.I'd like to ask a question regarding the frequency accuracy of the timer.Let me first explain the current ...
Hello, I have found various guides on how to configure the RTC as wakeup-source. However, they do not seem to apply to the C0 family.In the CubeIDE I cannot find the depicted settings on RTC, (most notably, no option to select internal wakeup and con...
I am using the NUCLEO-L433RC-P development board and in the process of designing my own PCB.But I am unsure what to do with the VDD12 pinsOn the NUCLEO-L433RC-P development board they are connected to an SMPS using an analogue switch.If I dont use an...
1. According to datasheet, STM32U0 family have an IRTIM (Infrared interface). But this section is missing in RM0503. Also in SYSCFG_CFGR1 there is missing IR_MOD and IR_POL bits.2. In RTC section Figure 297 it is missing RTC_OUT2 and RTC_REFIN pins. ...
Hello,We've been working with the B-G474E-DPOW1 kit with the intention of building a custom project board using the G474E. I've had success starting with the example buck/boost project in the STM32CubeIDE (1.18.1). Now though I need to move the HRTIM...
Hello,STM32F411CE microcontroller.What is FCLK Cortex clock for the STM32F411CE microcontroller (see Figure 1 below from the STM32CubeMX (Clock Configuration tab))? Is this clock related to processor clocking? As far as I know, the processor is clock...
Good Morning, I want to use a GPIO input or a ADC input as a logical reader which gives 0 or 1 if it reads 0 or 12 Volts. However, I know the maximal rating is normally 3.6 volts for those pins. However, i saw that the Adc can still read 5 volts, it ...
