I've be trying to learn CAN for the past few days for a project using 2 Nucleo F103RB and 2 CAN transceivers. I made a very basic code using normal mode and without using RTR. Now I want to learn how to code using RTR, can someone help me please?(I ...
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, newbie here - I have some experience with the f4 series, but am working on a small project for which I would like to try a stm32u0 MCU. Looking at the stm32u031 20-pin TSSOP, I am confused by something. When I load this MCU in cubeMX, and tick on...
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...
So, I've got a circular transfer working, sending 24-bit words to a dual channel SPI DAC (with hardware NSS), paced by TIM2 and working well. For every edge of TIM2 a word is sent. Since this is a dual channel DAC, I would ideally like the transfer 2...
Hello,I am using STM32F030C8T6 to implement Modbus RTU protocol which uses UART and RS485 as physical layer.I have already implemented the complete protocol with UART's RXNE and TCIE interrupts.Now I am trying to implement through DMA by which I will...
Setup: NUCLEO-H503RB with X-NUCLEO-IKS4A1, using STM32CubeIDE. To familiarize myself with I3C, I am playing around in this setup and have some source code which causes I3C interaction between controller and target. I have a logic analyzer attached, a...
Hello,I'm using LPUART1 (STM32U0) for modbus communication and using STOP2 mode to go sleep until new modbus query has requested.Strange things happen, on console I can see prints like "Target is not responding, retrying...".Here is my clock configur...
Hi Team,Could you please guide me on how to correctly configure the internal Flash memory for the STM32U5 series? Specifically, I would like to understand how to:Modify the Flash start and end addressesSet appropriate lengthsPartition the Flash to al...
Hi all,I wanted to make a post to shine some light on how to configure the HRTIM DMA on the STM32F3348-DISCO (and probably other ICs w/ HRTIM capabilities).A few posts I've seen have boasted the same solution, but have convoluted the use of a single ...
