STM32F207+ADS127L01 SPI
Hi there i cant get a real data from ADS1227L01. In debug mode i see the value 0xFFFFFF.Q1: If anyone used ADS127L01 can they send me librarys for comparison ? Q2: Im using 3.75MBits/s Baund Rate is it enough for 24 bit data?

i have some question in stm32H743 about fmc ,i want to write a 16bit-date to external sram(16bit width), i find , when i read a word(16bit),the NWE and NE chaged 4 times seems with address self-add,but i want one! what bothers me? the code generated...
Resolved! Implications of underclocking HRTIM
Hi, I've got a bit of an odd question but I'm hoping someone will be able to help or at least point me in the direction of some further information.I am currently looking at a project where we need around 10 PWM outputs so we were looking at using th...
How to know inner connections of DMA channels to peripherals on stm32g4 series mcu?
I have worked with f3 series and in user manual there is shown what peripherals are connected to each DMA channel. For example 4 peripherals are connected to one channel, that means I have to configure only one peripheral to use that DMA channel to s...
SPI Slave NSS input not consistent
So I'm having this weird bug I can't seem to figure out.I'm trying to connect two stm32f4 discovery boards through SPI.The master is sending out a SS signal I want to use to synchronize with the slave.However for some reason before I send out a messa...
hard fault when calling SBC_CleanDCache
I had some wrong bytes when transferring data over SPI, so I tried to clean the DCache. But I get a hard fault if I do this:I'm using the NUCLEO-H723ZG board.
QSPI memory mapped mode reads 0xFFFFFFFF everywhere
Hi everyone,I have followed the tutorial from ST to set the external loader :https://www.youtube.com/watch?v=XqCq0xtQmbIhttps://github.com/STMicroelectronics/stm32-external-loader/tree/contribHere's my HW config :I use the same QSPI (MX25L51245G) tha...
Hi all, I'm trying to configure my NUCLEO-H745ZI RAM as Device mass storage, i followed some tutoriels showing how to do this application with CubeMX and Keil IDE but its not working for me. I write my code only in "usbd_storage_if.c" file.
The code compile, load it to flash memory and enter debug mode to run the program.When i connect the usb connector present on the board to test if the computer will detect it as an usb device mass storage, nothing happen ! Can someone help with this ...
Unable to use PC14-OSC32-IN pin in NUCLEO-L152 Board
HI, i am new to STM32 controllers. i am using STM32L151RCT6 MCU in STM cube IDEJust i am trying to use PC14-OSC32_IN pin as input for external IRQ for falling edge configuration ..I not got the proper result , so just i configured that GPIO as input...
Resolved! How to wake MCU from sleep by USART event
I'm learning STM32 by a NUCLEO-L053R8 board. I want to put device to sleep (not LP Sleep, Stop or Standby) and wake it by either an interrupt or an event.int main() { // Clock and peripherals init // UART init (baud rate, GPIO, etc. are...
