I´ve read some MCUs support idle line events, but looking through the datasheet can´t see how to implement this.I could DMA 3 bytes at a time, but best would be to have DMA completion triggered after idle or timeout.
I think there is an error in the PM0214 Programming manual "STM32 Cortex® -M4 MCUs and MPUs programming manual". The multiply and accumulate instruction is called "vlma" throuout the whole document. Other programmin manuals (e.g. for STM32H7) as well...
I have a STM32-G071RB. I want to generate two sine outputs. one for reference and the second with a phase shift. Unfortunately, there is only one DAC port. I got an extra board but then I realized I need communication between the two boards to (I fou...
HelloI am trying to communicate with a Daly BMS in UART. I tried at first with an arduino board where I got the desired frame but when I tried with a custom made STM32F072 board. But during this test I can't get any response from the BMS.The BMS work...

I think there is an error in the reference manual (RM0440 Rev 7) in chapter 24.5 - COMP interrupts.At the end of this chapter it says: "Interrupt events are flagged through COMP_CxCSR flags."But in COMP_CxCSR register there is no flag for interrupt e...
I've noticed that the Nucleo STM32F072 has two jumpers (CN11 and CN12) that connect ground to ground. Does anyone know why this is? Are these jumpers used on another Nucleo board, and just hang out on the STM32F072 like a lot of the unconnected sol...
I am connecting the STM32L4 MCU UART to silicon labs IC CP2105 (UART to USB converter). The UART to USB bridge is bus powered from the type C connector and the STM32 is separately powered from the battery. When the CP2105 is in off state ( No USB ca...
Hi guys,I using keil uvisionV5.35.0.0arm_compiler : V6.16We are developing a project on STM32L071CZYx MCU. which has flash memory: 192kBRAM: 20KBI have attached a I2C1_IRQhandler function for your reference.void I2C1_IRQHandler(void) { I2C1->CR1 &=...
