I'd like an opinion on this issue with timers; I have working code, but it took me a while to understand that the code was actually working (though not while debugging).I'm using STM32F446RT.I'm configuring two timers so that one timer is a master, a...
Hello everyone.I am having trouble reaching the desired conversion frequency when attempting to have the ADC convert samples at a frequency of 384kHz( T ~ 2.6us ). The issue I've come across is that on each timer update signal, the ADC first has a wi...
I am studying STM32 timers (I have a Nucleo F446re) and I am wondering what is a use-case for this configuration Slave Mode: DisabledTrigger Source: ITR0Clock Source: Internal In my understanding you use ITRx when you want to cascade timers (i.g. TGR...
I have a timer (TIM10) with a period of 500 us, running without interrupt or any other function.Then I have a rising+falling signal interrupt on PB0 (EXTI0) driven with a 31.25 kHz square wave.In EXTI0 I read the CNT value into a variable New, evalua...
... 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...
