I am using the STM32H725ZGT6 for a new client application. I have used it many times before. This application requires three UARTs running, so I am using USART10 for one of them. I have not used USART10 before.My code runs all 3 UARTs the same -- ...
After a day of debugging, apparently HRTIM has minimum CR values, this means im not able to trigger any CR event close to the 0% of my scale, in my case this translates to a discontinuity in the lower end of my phase shift control. Is there any way a...
Hello and good year everyone,I am trying to follow the architecture below, where I read 1 ADC halfword at 2KHz via SPI. The idea is to trigger the DMA 1 Channel 3 as soon a new data is available in my SPI. It transfers my data from SPI to RAM. As soo...
Hello All, I need to design a board that will carry an IS42S32400F-6BL SRAM ,STM32H750XB MCU,Flash MT25QL512ABB1EW9-0SIT and Couple of support components along with Power supply.My questions-1) MCU Power Supply Protection2) High frequen...
Hi,i created this minimum code, where the dma for the injected conversions will not work. Only after each(!) start of a regular conversion, the injected conversion does work for one time. I have set it up, in a way, that it should work in circular mo...
In contrast to the STM32L0 that I am migrating from to the newer STM32U083, the U0 clock tree (Reference manual RM0503 V2.0 figure 11) does NOT show that timer clocks are PCLK*2 when APB prescaler>1.Also, it states in 5.2.14 that timer clock TIMPCLK ...
Hello, I have a NUCLEO U545 - REQ and i have a Queue in which i read the incoming values from 4 potientiometers from my ADC4 and send them directly into the DMA. The problem is that i also have the ADC1 connected to some potentiometers and im not a...
Hi everybody: First post here. I'm working with a GPS parser that re-sends data to another board, and receives some feedback from this other obard. BTW, both perform GPS parsing, with the same algos. One is Feather STM32F407 (the one with the problem...
Hi,Ive made a custom board with a STM32H735 micro on it. I have built a board with nothing but a micro and a few of its needed passive components and went to provide it power and test that its working. I supplied power from a benchtop power supply wi...
In the last weeks, I was working on running W25Q256 nor flash chip from vendor Winbond with STM32F746 MCU on a custom board. My guideline in this road is ST's how to run QSPI flash video tutorial (5-part video) and of course some genius guys in the c...
