Hello I am forced to erase the entire flash page when I write into an address of the flash page. Why is that? I have never used this page... I understand that if the flash has been already used, it cannot be rewritten... but why when the page is alwa...
I have been using a STM32F469i Disco board to interface with a 800x800 LCD in MIPI DSI video burst mode. In order for this to work from the DISCO board, I have an adapter PCB to connect from the DISCO board to the LCD.It took a while to get going, bu...
I'm currently looking at something like thisSTM32N657A0But they sell a non AI accelerator version STM32N655A0Is there any benefits to using the non AI version of the chip. Other then saving a few dollars on the chip?
I'm using a stm32G0 with a UCPD and i'm trying to figure out if the Dead battery pin have any other benefit then just saving the need for 2 resisters on the board. From my understanding i could create the same functionality of the dead battery pin by...
Dear, I'm using a STM32G0B0RET6 as MCU and I encouter a bug on GPIO external interrupt specifically on PC14. Configuring as external IT on rising edge, it works correctly and the interrupt is generated only on rising edge.Configuring as external IT o...
I have configured the comparator 2 PB6 on the STM32G071RB Nucleo board. It is configured for rising edge interrupt. As soon as HAL_COMP_Start is called on the COMP you can see the EXTI rising edge interrupt flag immediately go high. (well not immedi...
I have an STM32F4227 that identifies its USB port to a host PC and all information looks correct but no data is sent or received. Looking with the debugger the microcontroller is running task scheduler but does not recognize messages being sent. Is t...
During RTC init when RTC_EnterInitMode is called a unit sets the INIT bit of the RTC_ISR register in the HAL but when it waits for the bit set to respond it times out with the bit never being set. I have run this same firmware on hundreds of other un...
Hi,I am working with STM32G491RET6 and currently implementing the ADC. I have a question regarding the ADC reference voltage.If the external 3.3 V supply is removed from the VREF+ pin and VREFBUF is disabled, does the ADC operate using any internal r...
I am using STM32G491RE - NUCLEO.Similar to this post - ( https://community.st.com/t5/stm32-mcus-products/reading-data-with-brs-on-fdcan-line/m-p/745625#M266951)I implemented the function of receiving and transmitting data from the FDCAN line.I config...
