... or something I don't understand?Looking at RM0468, 2.1 System Architecture "Table 2. Bus-master-to-bus-slave interconnect" shows that DMA1 and DMA2 have access to basically everything except TCM, including APB4 peripherals and SRAM4.Is there some...
Dear Team,Currently, we have developed a prototype with an ESP32 and the prototype meets all the functionalities. However, we are now having some troubles scaling it to production. So now we are looking to migrate our product to using STM MCU. We hav...
Hi there,Iam using STM32F407ZGT6 controller, and we're interfacing DAC (MCP4902) with SPI2 and SPI2 is connected to DMA1. I need to transfer data in a circular mode using DMA1 to DAC using SPI, i have gone through the reference manual only TIM1 and T...
Hi,when it comes to programming and debugging, what is the difference between the 4 types (see screenshot below)?Which one is best and how do you decide which one to use?Please don't just say they all work the same pick one... :) I am asking for the ...
Hello,recently I was testing HTTP webserver project on a NUCLEO-F429ZI board and it works ok. I have created a driver for LAN9303 (dual port PHY) tested it using shield based on this https://github.com/ATM-HSW/MbedOS-with-LAN9303After it worked, I su...
Hello, I am working with my custom PCB with STM32L053R8T6. My code works just fine when I run it in debug without any stop mode (deep sleep). It enters to the RTC and button interrupts perfectly. However, when I want to make the MCU enter to sleep mo...
Hello,at the moment i try to verify the conversion time of the ADC that is described in the datasheet.I measure one channel in regular conversion mode without interrupt. To calculate the conversion time i used the equation in the datasheet.Tconversio...
I want to use crc hardware peripheral in STM32U535 for checking some modbus and I copied a code from this community thanks to @Tesla DeLorean . But in my case this code seems to work only for a buffer lenght multiple of four bytes. I can't found my e...
Hi team, We have our own customized USBPD board (STM32L562CET6) which support both SPR(100W) and EPR(140W). SPR is working great, now we want to work on 140W using EPR mode. So that initially we have tried to enter EPR mode by following method #defi...
Below is my main.c file. I'm wanting to scan analog pins PA0 and PA1. They work individually when not using DMA, but when I try to use DMA, the analog values are read once and then never updated after that. Any ideas? /* USER CODE BEGIN Header */ /*...
