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...
Hello everyone. I have a big problem with my custom STM32H7 board, in particular with HAL_Delay.When I add a line on my main.c file to simply print on SWV, the first time seems to work, but after it does not work anymore. It prints the first time, an...
I am using the above library to display simple text msg on the OLED display. It works. However the controller slows down - while(1) loop works as if delay(5000) is implemented. At first the internal HSI clock running at 8Mhz was being used. Thinking ...
I am using a STM32U545 Nucleo board with a purpose of measuring up to 8 Square wave frequencies simultaneously averaging between 100KHz to 1.5MHz. I only need to measure frequency with as much as accuracy achievable. Finally, I plan to transfer all t...
