It is possible for a CR2032 coin-cell to be inserted backwards in the holder. Therefore the VBAT (on a STM32F446) input needs some protection for reversed polarity. What is the usual method of protection?The datasheet shows a -5 ma as the current lim...
Hello everyone,I'm trying to use the FDCAN of the STM32H743 using the Tx FIFO. The board correctly receives all messages, but when trying to send them from the FIFO, it fills without sending anything. This is a piece of the code:if (HAL_FDCAN_AddMess...
Dear community members and Ambassadors, Embedded Survey 2023 is just out : It is interesting to see domination of C language by far and that a processor vendor’s brand weighs heavily in the decision process. “The embedded study lists highlight the...
Hi, team.I'm working on STM32L151 and have implement data transfer over USART + DMA, the implementation is very closed (but contains some modifications) to the following example:https://github.com/MaJerle/stm32-usart-uart-dma-rx-tx/blob/main/projects...
I am reading datasheet AN2867(Oscillator design guide). There are two formulars : ESR and gmcrit. It's common formular and easy to find it from internet. My question is where are these formulas from? (How to derive these formulas?)AN2867 Rev 18, shee...
Hi,I am working with STM32F100RBT6B. I am getting "command not supported" error while flashing the code using Keil Ide with ST-LINK V2 debugger. Please help.Thanks.
Hello. I use Timer 2 on STM32F401CCU6 to read rising and falling of clock signal. Timer 2 channel 1 in Input capture direct mode (Rising), channel 2 in Input capture indirect mode (falling). I registered an timer callback event and do some calculatio...
Hi,I need some initialization code for STM32L4R9 to drive a DSI display (1.2 rounded) 1 line. I cannot find any reference online on how to drive this kind of display. I also have initialization DSI frame from display manufacturer but I cannot make DS...
