Greetings,I have connected external crystal of 32.768 KHz to STM32F205RG for RTC time keeping purpose. I have also enabled RTC output on pin PC13. Below is my code for RTC Initialization ...int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE E...
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 ...
Hey All,I hope you can help me. I'm trying to bring up my new board, which contains a STM32N657IO. Attached are the schematics. You can assume the 5V supply is working(it is after a few bodge wires). My problem is as follows. I'm trying to connect to...
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...
Hello everyone,I'm currently working with an STM32F746 microcontroller as an SPI slave using DMA for data reception.The SPI master sends fixed-size packets of 512 bytes, and everything works fine most of the time. However, occasionally, a few bytes (...
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. ...
