Posted on July 06, 2018 at 00:04I have a F446RE, with 5 devices connected to USART1,USART3,UART4,UART6,USART6In each case, i have DMA reception configured, each with decent size buffer.A have a 3 device versions, 2 work without issue, but model seem...
Posted on July 05, 2018 at 16:12How often a peripheral can interrupt the 168MHz STM32F4 series MCU in general? In our senario ADS1282 need to transmit data to MCU on different speed from 4ms interval to 1/4ms interval, and maybe even faster. That me...
Posted on July 05, 2018 at 20:36I am comparing the differences between the project/application for the STM32H7 FatFs example in FatFs_uSD_DMA_RTOS and a project created using CubeMX (w/STM32H7 V1.2.0) for the H743i_Eval board. One of the difference...
Posted on July 05, 2018 at 23:25Hello,I am working on an application that uses the STM32F207IGT6 microcontroller, using uVision 5.21.1 as IDE. This is a legacy application that has been working for months now, but it needs an update to add functiona...
Posted on July 05, 2018 at 18:47Hi,I just generated two identical PWN pulses using two separated identical timers in the STM32F407 chip. After the MCU resets or a momnet after the MCU startup, both PWM pulses overlap each other as naturally should b...
Posted on July 05, 2018 at 19:23I am trying to understand a potentially simple issue that I don't seem to be able to wrap my head around. I am setting up a simple bit banging PWM using system timer (running at 100 KHz or 10uS interval) and a GPIO pi...
Posted on July 05, 2018 at 23:44 I'm trying to set an interrupt to occur each time my rotary encoder detents, however this doesn't seem to be working.What am I missing? This is how my timer function is setup: #define ENCODER_PPR 20 #define ...
Posted on July 05, 2018 at 19:36Hello all, I am urgently looking for a Flash Programming Algorithm for the S25FL256S or S25FL512S Quad SPI Flash Device. This device will be used on a board with an STM32H743i processor. I use Keil as Development Envi...
Posted on November 15, 2016 at 07:54Dear all,for a project I have to implement a SMBus communication with a battery. I already found the X-CUBE-SMBUS Software but it seems that it is only compatible with F0 and F3 Controllers. I also saw that these ...
