HI,I am working on a board using STM32H573V and have a working solution with UCPD detecting an inserted memory stick and running the MSC class. In an other part of the software I am using PC9 as an GPIO push-pull, low speed output and as soon as I se...
I'm working with an STM32F411 and trying to run two I2S master-receiver interfaces (I2S1 and I2S2) at the same time, each receiving data from a pair of PDM microphones using DMA circular transfers.However, I found a very strange and extremely hard-to...
Hello everyone, I’m new to STM32 and I’m currently stuck with using timers.I’m working with an STM32F303RE, and the goal of my project is to generate 6 signals at 100 kHz (high time between 100 and 500 ns), each phase-shifted by 60°. These signals wi...
Pls cross TI part number TMP75AIDGKR (Temperature Sensor With I2C and SMBus Interface) Previously there's a Cross Reference tool in ST website but it's gone. I use it regularly. I hope it can be reinstated.
Hi, I need a little explanation about what is wrong behind my reasoning..I am using STM32F411. reading, two inputs of ADC in scan mode over circular DMA triggered via TIM2 update event.TIM2 is triggering ADC at 100KHz, so I have 50Khz sample rate per...
The STM32H743XGH6 is specified to have 1 MB of Flash memory.However, it seems that the following 2 MB address ranges are writable:BANK1: 0x08000000 to 0x080FFFFFBANK2: 0x08100000 to 0x081FFFFFIf the device really has only 1 MB of Flash, I would expec...
I have strange DMA problem with a F303 application, in particular a STM32F303K8 (a STM32F303x6/8 variant).The concept is relatively straightforward.A configured ADC sequence is triggered by timer, the ADC in turn triggers DMA transfers of the convers...
Hi, For STM32F446RET6, I want to use the DAC function of it. But I have some question. 1. If I don't use the output buffer, what is the output range? From the datasheet I think it should be 0.5mV to 3.3V±1LSB？2. If I use the output buffer, what is th...
I am using STM32WB55 and entering STOP2 mode for low-power operation.RTC Wakeup timer is configured, and the interrupt works correctly in RUN mode,but the MCU does not wake up from STOP2 mode when the RTC wakeup interrupt is expected.Configuration:- ...
Hello dear ST forum.I need again you precious help.I am working on a data acquisition device, and need to get 14bit data from a parallel ADC connected on DCMI pins,at 48MHz, and move it to a 32MB SDRAM (W9825G6KH-6I) till almost full. The MCU is STM3...
