I'm currently designing with STM32L152RET6 . As I encounter some problems in SPI behaviour, I'm looking for the STM32L15xE errata sheet (ES0235) , the link I found points to 404 ...Please tell me how to find the errata sheet.

How many slave devices can be connected in part STM32F303ZET6 using SPI interface? I am planning to connect directly 40 ADC (AD7719). Is it possible with the 4x SPI available? I am preferring CS mode.

Data Acquisition system in that i am interfacing AD7768-4FMCZ with STM32F103RCT6 . Here i am receiving data to DMA through 16bit SPI . Am Receiving Data but am not validate according to Data Sheet .

Anyone Have hands on experience .

DMA loses data in transmission, for multi-channel adc.

Hello everyone, I use three adc blocks including ADC1, ADC2, ADC 3, and DMA to transmit data. However, DMA data transmission has lost data. Below is my code.  #include "main.h" #include "usb_device.h"   /* Private includes ---------------------------...

Modify PWM frequency on the fly (STM32F4)

Hello, Community.I am currently trying to control a power converter with a STM32F4 microcontroller. The thing is that the control variable is the frequency of the PWM. I have programmed a timer (TIM3) that generates an interruption every 100us. Durin...

Unable to get 0 or 100% duty cycle in up-counter mode

Dear community I am new STM32G4 family bu i have several years of experience with C2000 form competitor TI. I would like to use STM32G4 controller in new project but i have lots of problems. I have read AN4539 HRTIM cookbook and HRTIM chapter in Refe...

Is the bootloader host code available in some form?

I am working on a project where several STM32L0xx processors will be running under a Raspberry Pi 4+ system. The desire is to be able to use the SystemBootloader on these to be able to do firmware updates. I know that the documentation from ST is eno...

Generating a DFU file from Hex from bat

I want to be able to run a bat file that has inside it the path to a hex file. When i run it, it converts it to a dfu file, without the user needing to do any more clicks or inputs. I tried to do this by using encedo's hex2dfu from github. The proble...

How STM32G0Bxx PA11/PA12 pad remap to PA9/PA10 works and for what is useful for?

Hello,Reading the datasheet, pads PA11 and PA12 can be remapped to PA9/PA10.I don't understand how this remapping works.Variant A-------------This is a full swap, meaning that pads PA9/10 will exchange with PA11/12 ?Variant B-------------Pads PA11/12...
