I need to perform lot of mathematical calculations and within a fixed time interval, the micro is STM32G474 my question is even if floating point calculator is available, do you recommend to use fixed point calcuations Q15 format etc. or I can go ahe...
Title edited to clarify that this is on a Nucleo board.Hello there, as a way to study embedded programming I decided to perform various tasks on the board, including firing an interrupt on button pressing to light up the 3 user LEDs.I got stuck, the ...
Hi, I'm seeking some advice on using a STM32U5A5 in USB device only via a USBC connection.Any previous USB "device only" designs I've worked on only required connections to D+, D- and ground to communicate. These designs have been USB2x.The U5A5 has ...
Hardware connectionNode A: STM32F423RHTx, TCAN1462-Q1 transceiver, HSI→PLL→80MHz SYSCLK, 40MHz APB1, PA11/PA12Node B: Arduino Uno + MCP2515 breakout (8MHz xtal, onboard transceiver), mcp_can v1.5. 120Ω termination, wiring verified CAN Timing (both at...
Hi Team,I am working on board design using STM32H745 (LQFP176 package), and I would like to confirm the correct external memory selection for my smart kitchen application.Application details:- MCU: STM32H745 (dual core)- Package: LQFP176- USB OTG FS ...
Hello everyone, may I ask what is the maximum clock frequency supported when the STM32H7's FMC peripheral controls SDRAM? Can it work stably if the frequency exceeds 200MHz, for example, 240MHz? Thank you very much.
I am trying to do power profiling of nucleowba25ce1, but when I remove the JP2 jumper and then after connecting VIN and VOUT to JP2 pin 1 and JP2 pin 2, then I can connect it to the cube programmer also, and I start getting readings also, but only af...
I am currently struggling to figure out if my current requirents are even possible.I am building a network controller to controll laser projectors via analog lines.For that I have an DAC8552 connected to SPI1 and a DAC1240S85 connected to SPI2.The wa...
What are the differences between those two devices? The datasheet only says that the N means "N product version". In the STMicroelectronics eStore, the only difference is that there's a Material Declaration for the STM32C071RBT6, but not for the STM3...
Section 36.6.1, Bit 18 (ITAMP3E) indicates that LSE frequency monitoring can be enabled. It appears that the hardware automatically detects when the LSE frequency goes above or below the defined thresholds and sets the ITAMP3F flag in the TAMP_SR reg...
