Dear al!i need your help, i design PCB use STM32H755ZIT6, i set up mode PWR_SMPS_1V8_SUPLLY_LDO via STM32CubeMX 6.12.1. I expect core M7's clock is 400Mhz, M4's clock is 200Mhz. I measure voltage after L2 is 1.8V, at each Vcap pin is 1.0V, The MCU wa...
Hi everyone, I am encountering a critical issue with the IWDG on an STM32U375 using STM32CubeMX v6.17.0 and a Segger J-Link Base. The scenario: I am testing the Watchdog behavior across Standby cycles. I have configured the Option Bytes via software ...
Hi,I do not plan to use USB or CSI, and the board only receives 1.8V power. So, I asked how to connect the VDD33USB pin, and I was told to just connect it to GND. However, I have two more questions.I currently have the VDDA18USB and VDDA18CSI pins co...
I'm working on a project using the STM32U385 and I'm trying to find a way to detect a specific condition and save data while the device stays in a low-power Stop mode — without waking up the CPU to do the saving.Is there any peripheral combination or...
Hi everybody,I'm working on a STM32F446. I'm using the UART.I've a function with switch/cases which instead of a function number fill a buffer.ex :switch(function) {case 0x00 : Txbuffer[idx_trame++] = 0x00;break;case 0x01 : Txbuffer[idx_trame++] = 0x...
Hello, I wanna use the development board STM32N6570-DK for taking a picture with MB1854B. i am quite new for DCMI and DCMIPP. i just want to read the image through the pipe1 of dcmipp but i dont know how to config the MCU in .ioc file. Can anyone exp...
Split from this post. Thank you for your help, I didn't know this mode and it works well. I did a measure every 5s. I use Timer1 for injected mode and timer3 for DMA mode. I've just a little difference of measure. With the ADC, I have the following v...
Hello everyone, I am working with the STM32H743BIT6 using the LTDC peripheral to drive an RGB display. The display I am using does not have HSYNC and VSYNC signals and operates only in DE (Data Enable) mode. I have attached the display datasheet for ...
Hi team, We have our own customized USBPD board (STM32L562CET6) which support both SPR(100W) and EPR(140W). SPR is working great, now we want to work on 140W using EPR mode. So that initially we have tried to enter EPR mode by following method #defi...
I am planning to do an aging test which need capture the voltage of a net, but i found STM32U585OIY6QTR report a value about 40 while the actual voltage of ADC channel is close to VREF.Then i write a simple ADC demo to verify ADC configuration, and r...
