Greetings,I'm using a low power microphone and would like to turn it off when not in use. That is done by turning off the clock to microphone, which is generated in ADF as output clock. Stopping sample acquisition (either by TRGO using window mode ac...
Hello all,When I run the code, it works as expected, but when I unplug and then plug-in again, the system halts and when I debug it, it is like the USB_IRQHandler() is being called in succession very fast as if the IRQ pending bit is not reset. The v...
I'm currently using a stm32f767 board and I'm going to try lcd this time.I need to use spi 9bit to write my lcd, but I set the data size to 9bit in the settings window.I want to implement it as ST7701.Below is the mode and code I set.Please check if...
Hey, I'm using the STM32H743ZI device.I have an odd issue, but I will explain the setup first.we have 2 SPI channels with DMA that receive lots of data at a high rate from an external device.the STM receives the data from the SPI and does a small con...
We have a very weird behavior in a battery powered IoT device. We should have a very low STOP mode current draw of 1.4 uA @ 3 VCC. The problem is, as soon as we use the RTC Alarm just once and although the alarm already fired during NORMAL operation,...
Hello, I am using the NUCLE-F103RB and the STM32CubeIDE for developing and testing code. After my latest code change the program does not return form the below call of HAL_TIM_Base_Start_IT(&htim3)."TEST1" is printed to the terminal, but "TEST2" is n...
I am using the stm32f4 discovery board and writing bare-metal drivers for the embedded flash memory.I am facing a strange problem when writing to flash memory, to save you time for reading code and when the error happens, here is the status:Before Er...
Hello all,I'm using STM32F407 ADC1 with DMA enabled for sampling on 4 channels at same time, the configuration for these 4 channels are all same with DIV4 clock and 12Bit Resolution, but only 3 of them are working fine, and one channel always returns...
ST example uses 400MHz / 4 = 100MHz for SDRAM. What should the SDRAM clock be when the system is running at 480MHz? If we use 480/4 then it is 120Mhz for SDRAM, but datasheet shows max of 100MHz for SDRAM! Are we stuck running SDRAM at 60Mhz? Or run ...
Hello.I would like to use the STM32G0B0RE to write and read about 1KB of text data from an STM microcontroller to a USB memory device.When I looked for sample code to do this, I could not find any.So is there some kind of beginner's guide for writing...
