Software configuration of SPI NSS to run multi-slave one master SPI system for STM32L412 chip

I am hoping to understand more the process behind this. From what I understand, the NSS can be in either a hardware or software configuration. Reading the reference manual [Section 40.4.5], it appears that if the NSS is placed in software management ...

Finding issues in initializing the USB as CDC in the STM324x9I-EVAL board.

I am trying to establish communication between windows 10 and SMT324x9I-EVAL board through USB by setting USB in CDC class.For starting with, i have used example application given with stm32f4 peripheral library package(en.stm32cubef4\STM32Cube_FW_F4...

During nand flash erase, uart interrupt doesn't work properly.

Dear allDuring nand flash erase, uart interrupt doesn't work properly. (same SysTick_Handler)Let me know why this is happening.nand flash erase source :for(Addr.Plane=0;Addr.Plane<2;Addr.Plane++){ for(Addr.Block=0;Addr.Block<2048;Addr.Block++) { HAL...

Bug in HAL libraries when using multiple DMA request to different channels of same timer

I am having a problem getting two DMA requests started for the same timer. One capture is an IC (input capture) and the other an OC (output compare). See the following code snippetHAL_StatusTypeDef status; status = HAL_TIM_OC_Start_DMA(&htim3,TIM_CHA...

Chip selection for 2-port CDC host

I need a 2-port host that can bridge 2 CDC slaves. What is the best chip for doing this? I don't want to spend much time doing software development like writing CDC drivers.

STM32L412 VDDUSB Disconnect

I am using STM32L412RB for a low power application.VDD: 1.8VI have a 3.3V regulator that I would like to only turn on when I am using USB. According to the datasheet (https://www.st.com/resource/en/datasheet/stm32l412kb.pdf pg 19), VDDUSB = 3.0 to 3....

How to compare bytes received in a uint8_t?

I have a STM32F103C8T card, I am developing an application that receives a byte array by usb / serial.I have a variable "uint8_t USBBuffer;" in "usbd_cdc_if.c" which stores the bytes.My question is: how can a non-vector variable receive an external m...

A barrier to "generate code" for a new project in CubeMX

Hey guys,I used ST CubeMX(v5.2.0) with TrueSTUDIO IDE in Windows 10 PC. My work is to generate a new project for STM32 F411E DISCO board and tweak and implement the examples given for STM32 F446RE board in the ST's FP-AUD-SMARTMIC1 software's projec...

How to properly change sysclk frequency in STM32L0

Hi,I'm trying to dynamically change sysclk frequency in STM32L011xx. It's quite easy for STM32L4. All steps are described in detail in RM for L4 (here is what I extracted from RM: https://pastebin.com/KcCZNGAr) - my implementation here: https://githu...
