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...
Posted on November 26, 2015 at 17:56Hi,I'm experiencing a very bad behavior of HRTIM.if output set register is set on Period and output reset register is reset on CMP1.if CMP1 = 0x20, the PWM output is a narrow pulse as expected. but if the CMP1 < 0...
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...
I'm working on an STM32 project using X-CUBE-CELLULAR to support both cellular modems: BG96 (or GM01Q). I physically connected both modems (2× STMod+ expansion connectors) to my STM32 board.My main question is: How can I configure my project and step...
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...
