Hello,As per CM4 guide and TRM of Nucleo f446re,interruot vector table is array of function pointers and each pointer holds the entry address(initial address) of each IRQ_handler, Where interrupt IRQ_number is used for indexing.While debugging I fail...
Hello Experts,I am using the STM32L476QEI6 in one of my projects. The system VDD is 3.3V, and VBAT is supplied by a 1.55V coin cell battery (Murata SR621SW).The tamper pin (PC13) is connected to an anti-tamper switch normally closed (NC) — meaning th...
I have an odd issue. I am setting up a timer compare channel for a 5ms delay in the future. I set the counter to 0, set the compare value to 5ms in the future. The compare interrupt does not occur, until the timer wraps all the way around and pass...
Dear together, For the past dew days Im stuck kwith UART communication with DMA.To start with, I am implementing TX now. Later I will implement RX. I have managed for TX to work without interrupt. As per my application, I need Interrupt to inform the...
Hi all,We’re a small startup developing a commercial product using an STM32H755ZI, and we’re getting ready to ship. One of the key things we want to bulletproof before launch is firmware recovery for end users, especially in case the firmware upload ...
Hi All,I have a project that is using the STM32H562. I am having an issue using tim13 and tim14 to generate PWM outputs going to LEDs. The project uses timers tim2, tim3, tim4, tim13, and tim14 for a range of different PWM peripherals. For all of the...
Hi,I am testing the ECC on DTCM on the STM32H7A3ZI. At start of day I initialize all of DTCM apart from a single test location. I have a test which reads from that uninitialized location and successfully provokes the SRAM ECC interrupt, correctly r...
Hi all,I'm working on a very low power custom board powered by a STM32C011D6Y micro controller. I must read an ADC input routed to F1 ball (PA3, PA4, PA5 or PA6) but I'm measuring some strange power consumption related to the input voltage on the pin...
Hello,I’m working on a custom board based on the STM32H753IITx and I'm trying to access a microSD card via USB_OTG_HS using the USB Mass Storage Class (MSC). I've read this post, which is close to my use case, but unfortunately, I haven’t been able t...
I want to make a communication between 2 microcontrollers by can protocol i put after each microcontroller a can transceiver and the problem is that we send data but i other board we don't receive it, i mean after the second receiver we don't have p...
