Dear ST Community,I am currently migrating my Firmware from STM32H723VG to STM32H563VI. I have problem with Internal Temp Sensor. Based on Reference Manual on both MCU reading temperature is the same, but it doesn't work as it should.When on STM32H7 ...
Hello,I want to change for boot to use XSPI1 interface, but I am not sure about OTP bits, there in description some bits is not very clear, what OTP bits to set to switch if it's possible ?Additionally if I will use SD card for boot I can set OTP11 v...
Say I am operating as master with CPOL=1. Because the NSS pin seems to lag the enable bit (SPE) slightly, my logic analyzer always barfs on the first SPI packet because the clock is in the wrong state.So, I set the GPIO to have a pullup on the clock...
I'm working on a design with an STM32L072CZT6TR, where I want to calibrate my main timebase. That main timebase is TIM6, which counts 16,000. The HSE is 16MHz, so there's an interrupt evey 1ms. Calibration is done by counting the number of HSE cycles...
Hello,I’ve recently started using ST products and the IDE with CubeMX, which is why I’m asking for your help. I’ve just begun developing a communication system using a Nucleo H743ZI2; my goal is to set up a UART and a CAN bus.The UART is done; I used...
For STM32H7, if the FMC data lines and SDRAM data lines are cross-connected (not D0 to D0), and address lines are also cross-connected (not A0 to A0), can SDRAM work properly? My PCB is about to be manufactured, but due to the hardware engineer’s des...
According to the PD 3.1 requirements (also PD 3.0), I need to connect UCPD1_CC1 and UCPD1_CC2 to USB-C CC1 and CC2 to communicate and request the desired voltage. But STM32G0B1KBU6 has only UCPD1_CC1 available. Is there any way to connect STM32G0B1K...
Hello,the SPI does work with NSSP(Negative Slave Select Pulse-Mode), but it does not work if I disable NSSP. As someone pointed out the SPI NSS(P) may only work if the Pulldown of that pin is enabled, but I’m not 100% sure on that one, but it seems t...
Hi,is there any HW guidelines to configure a USB OTG port with STM32H563VIT6 with VBUS detection?
Hello.I recently experienced an unusual MCU Problem and need to analyze it. Please help me. The FW program download to the MCU is successful, but it does not operate after a reset. I performed a short circuit test after disconnecting the power(Batter...
