Generating 1 nanosecond update event using Timers - AN4013
According to AN4013 on using timers as time base generators, one could use a 16-bit timer to generate an update event from a nanosecond to a few minutes. Well, take for example the STM32F429 clocked @ 180 MHz. If one cycle takes 5.56 ns, which is the...
Modbus over RS485 with STM32F303K8
I'm looking to make a loop of MCUs as slaves to a PC master so that I can send commands to them. The idea is to use the https://www.maximintegrated.com/en/products/interface/transceivers/MAX22025.html and https://www.ftdichip.com/Support/Documents/Da...
STM32L476 LPRun Mode external clock source Frequency
I'd like to you a STM32L476 continuesly in LPRun Mode with external Oscillator Frequency of 2.048MHz. But in "Reference Manual" of STM32L476 is written following: "5.3.2 Low-power run mode (LP run)To further reduce the consumption when the system is ...
Abnormal delta of TSC after exiting STOP mode
Hi,MCU: STM32L072MCU is using TSC and ST touch sense library. Before entering stop mode, the delta of touch key without pressing is normal (-2 to 2). However, after exiting STOP mode and then calling tsl_user_Exec_IT(), there is strange value delta.B...
STM32H743IIT6
Left side original label from MFG but there is a misspelling on the temperature.Right side label from Mouser with the correct spelling.Please advise whether it is a common error on the misspelling issue.
QUAD SPI MT25QL128A with stm32H750Ibt6 controller.
Hello all,Currently i'm working over STM32H750IBT6 Controller with QUAD SPI MT25QL128A External flash. The objective is to boot from internal flash address which is 0x08000000 and jump to external flash address, as the internal flash memory is quite ...
QSPI NOR flash on top STM32, may I know if QSPI NOR flash can work half as memory map and half as block mode ?
A file system runs on half of NOR flash (64M) as raw block mode, and the memory map mode (32M) run other half of NOR flash (32M run code as XIP). These two modes don't need work same time.May I know if that is possible?Thanks a lot for advise.
How can I use external flash and ram with X-Cube-AI on the STMH747XI-DISCO board?
I want to run some AI models on the STMH747XI-DISCO board that are too large for the onboard flash and ram. I have absolutely no problem setting up the project with Cube AI and getting the model loaded. In the network Advanced Settings, I have extern...
