I should combine STM32F479 with PROFIBUS-DP ASIC SCP4-2 The chip is aged. And requires delay of at least 30ns (by 3v3) between address and cs. Our previous design was based on SAM4S and their CPUs are offerring register to program such delays. In STM...
I am having some strange power up (I think) issue with my STM32G431 controller. Sometimes it runs for a second or two, sometimes nothing. It will usually not connect via the SWDIO pins so it is difficult to step through in debug to see where the pr...
I am using STM32F103C8 MCU and Trying to communicate with Quectel EC200U-CN 4G module and i am not getting data through UART2 Receive pin. Please go through my code and suggest mevoid USART2_IRQHandler(void){ if ((USART2->SR & USART_SR_RXNE) != RESE...
Hi, i m trying to program PowerStep01 with SPI on STM32H7, can anyone kindly advise where to locate sample code and tutoral ? or programmer user guide? A serach online yield this but error on page and file not found. https://my.st.com/content/my_st_...
In RM0456 section 73.4.3 OTG_HS core (p.3279) I found the following statement:"The OTG_HS receives the 60 MHz clock from the reset and clock controller (RCC). This is typically generated in the PLL associated with the HS PHY and enabled in the RCC. T...
I'm new to working with ADCs on STM32. I'm reading a rectified voltage using ADC with DMA on an STM32G0B1. I know the ADC conversion time from the datasheet but I want to compare the ADC's output with readings from an oscilloscope. I'm plotting the v...
Sorry to bring up the elephant in the room. I just reviewed the ST Q1 quarterly results from April and was astonished to not find anything related to lead times, shortages, or allocations.My company is in the Musical Instrument space. We work with a ...
Hello everyone!I have started a small journey to try to get started with eMMC memory and are trying to get it working.The end goal is to have a USB HS mass storage device eMMC working with a file system. (32gb or more) My current step that I'm stuck ...
Hi, I'm having a problem with unintentionally splitting a message I'm trying to send over the UART using DMA . I am using one function to send the message:const uint32_t max_value_of_counter_loop = 100; /* in case systick jams */volatile bool was_u1_...
Hi there,We use a STM32F723 controller and want to connect two external RAM devices.Now we have to select a RAM that fits to the FMC. What we can't find in the reference manual RM0431 is, if SDRAM-DDR functionality is provided or only SDRAM without D...
