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...
Hi everybody,I read 15 analog channels with DMA on my STM32f446. It works very well (It's tiggrered by TIM3 every 200ms).So I'd like to add Vbat. First, I've added it as the 16th channel of DMA, it works, but I saw the battery voltage decreases (arou...
Hi ST team,I am seeing what appears to be a silicon-level issue on STM32H563RGV6, revision X, related to the SWAP_BANK option byte.When SWAP_BANK is enabled, a USB OUT endpoint stops being re-armed during a flash mass erase of the inactive bank. The ...
Hi, I have an stm32g473 which use the clock of another system as external clock on PF0 / OSC_IN. This clock is them multiplied by 74 through the PLL. I need to synchronize my code with the external clock (i.e. wait for it to rise). What is the simp...
