我们这次购买的芯片上没有ARM标记，右上角的版本号改成了二维码的形式。 请咨询我们的供应商，不同的产地/包装厂/批次会有所不同。但是我们的质量部门不会库存它们。 标记的变化比较大。此标记更改是否有相应的文件？ Translation: There is no ARM mark on the chip we purchased this time, and the version number in the upper right corner has been changed to a QR ...
Hi Team, Currently I am using STM32U58I-IOT02A Board and implementing UART Transmit and receive, I am seeing that it is not printing anything on the PUTTY terminal, Can anyone suggest me how to handle this issue. I have tried to send with HAL_UART_T...
Im using the following code that is part of a metal detector I'm building. Im trying to trigger the ADC based on TRGO of TIM2 (I need dma / adc readings every 10us after the of each TX pulse). I expect the TIM2_IRQHandler interrupt to enter 10us (ADC...
Stm32F746G DISCOMy program was written to accidentally flash a value to be stored in the wrong location. the display would be unresponsive so I'd reboot it without issue. My software still worked normally, it's only when it encounters that line. How ...
I am trying to configure the HS OTG port on the STM32H747I-DISCO dev board, but setting "Use external vbus" seems to be not enough. I can measure 0.8V on the CPEN line (measured from R11) but I don't see anything on the OUT line of the voltage switch...
STM32G473CB has 3 DAC channel outputs. a. Can these three DAC channels output a 100KHz triangle wave signal at the same time? b. In addition to the triangular wave, can the output signal output an irregular 100KHz waveform? thanks
Hello,I'm new to stm32 microcontrollers. I'm trying to figure out how to configure LPTIM1 in counting mode, external clock in using cubeMX. Is there any examples on how to set it up?Is this even possible?Thanks in advance.
Hi, I am using STM32G0B1KC ad usb device. I will show you all the conficuration for USB_DRD_FS and USB_DEVICE middleware.I am using the internal HSI48 for the USB clock.When I connect the device to my PC, the device is not recognized.Can anyone help ...
Will STM32H743BIT6 support only OTG_HS mode? Will it support normal USB operations by disabling OTG option? If yes which pin will control that functionality?
Hi, 1. In order to calculate the values of pull up & pull down resistor, in which section can we find the impedance information?2. Should we use external crystal for OSC_IN & OSC_OUT pins?3. If we are using USB2.0 FS feature what is the reference?Tha...
