We have 3 DMA interrupts DMA1_Channel1_IRQHandler, DMA1_Channel2_3_IRQHandler, DMA1_Channel4_5_6_7_IRQHandler, i need use 3 interrupts beer 2 channels because i use 3 usart with DMA (3 x channels for TX and channels for RX). 1- i can split the chan...
Hello!The what I want is to configure the ADC 16-bit synchronous sampling from 2 ADCs and 6 Sigma-Delta using DFSDM at 1kHz period on M4 core to circular buffer. I'm not sure how to do it right, but I'm suppose that I need to enable say TIM1 at 1kHz ...
Hi ! Im generating pwm at 200khz with no problems. But when I use timer to generate interrupt I get max 100khz of pulse on pin. No matter if I use HAL_GPIO_Toggle/WritePin or just GPIOx->BSRR. No matter how low value of timer prescaller I use.Outpu...
Hi!I am confused, i wanted to use STM32F042F6P6 MCU for can interface but, ther is no TX pin for can interface (PB9 on datasheet). So, how i can configure CAN TX?There is no CAN mode option for this MCU inside of CUBEMX because there is no TX pin for...
Hi team,I am using STM32F103RDT6 for my project. I would like to know the details of UART in the MCU. in the datasheet it shows 5 USART interface is possible. At the same time 2 UART is also mention in the datasheet.So my doubt is that can I use the ...
Are there control signals available that would allow me to "unmux" the address/data lines using external latch? I need to use the LQPF144 package that doesn't provide the separate Address and Data pins - they are muxed.
Using HAL. How to read unique ID and use it to identify specyfic chip?Do simple:uint32_t HAL_GetREVID (void ) uint32_t HAL_GetDEVID (void )Do the job? Are they really unique, or can these values repeat in same chips?
Hi,i want to put my device STM32L010 for 5 minutes in stop mode. Then wake up to measure something with ADC and go in stop mode again.How can i handle the IWDG in stop mode? According to the reference manual, the timer cannot be stopped. ???17.3.4 Be...
