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...
Hello EveryoneI am trying to build libcsp source code for STM32F429 Cortex-M4 MCU. I am using Keil MDK-ARM V5.22 IDE for my software development. Please tell me how to configure/change wscript (waf script file) to build libcsp for STM32F429? When I r...
Hi,I have a problem about I2C and I saw some topics about my problem on the internet but there was no solution, I hope you help me by sheding light on this.Problem : After sending adress by I2C, the ADDR flag in SR1 register is not set but at the sam...
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.
