Hi,I am using an STM32U545 on which I expect to use ADC4_IN1 and ADC4_IN18 in stop mode 2 (using LPBAM).I want to create two buffer (buff1 and buff2 uint16_t[32]) dedicated to each input.I want to read 32 samples from input1 then 32 samples from inpu...
Hello Dear Community,I am working on an HMI System and using STM32H7B0 with APS6404L-3SQR. I am able to do all operations including Write in Memory Mapped Mode but when I try to write 1 byte, It writes 8 bytes which is not what I expect.I have read m...
Hi Community,During a project we are using the microcontroller STM32H7B0RBT6 with QSPI PSRAM APS6404L-3SQR , it works fine in indirect mode either in quad read and quad write, but the issue is with the write in memory mapped mode when trying to write...
The STM32H7 reference manual (stm32h723zg.pdf) contains several tables describing he pin mappings (pin to functions).In Table 7 and 8, for pin A0, A5, and A15, it lists the pin function as "TIM2_CH1/TIM2_ETR" for alternate function #0. Should this be...
Motivation: Release a product (STM32F072RBT) with no buttons or toggles on the PCB and allow customers to flash and interact with their product over USB serial interface. Requirement: Keep BOOT0 held high so the STM32 is in DFU mode upon initial conn...
Hi all, I currently work on STM32F030K6 . I am working with a reed switch connected to pin PA8 (EXTI8). I havec onfigured the PIN like : "external Interrupt Mode rising/falling ....I need to perform an action on the rising edge AND on the falling ed...
1. I have modified the STMxxx_Flash.ld linker file by adding some memory sections. Does the sequence of SECTIONS definition matters? LinkerScript.ld and MPU Config Added.Layout:ITCM -> Has some functionsDTCM-> non DMA Global VariablesD1 RAM (First 2...
Hello STM community, I am new here. I recently decide to learn embedded systems and I bought STM32F3 discovery board having the STM32F303VCT6 chip on it.But I am facing the issue in serial wire debug. In the SYS, when I try to choose the Serial wire ...
Hello team, which of the STM32 microcontroller is able to generate single trigger pulses in steps of 100ns +/- 10ns? Best regards,Jochen
Hi,I am using STM32F103C8T6 Blue pill board, STM32 CubeIDE 1.16.0, Build: 21983_20240628_1741 (UTC) on Ubuntu 22.04.5 LTS and ST Link v2 debugger. I am able to upload code, execute it and debug it via SWD.I am using CubeIDE's Pinout & configuration u...
