Ask this at arm.com, but maybe it is STM32U5 specific:I try run an unprivileged application in secure mode and get a strange behavior:STM32U5 has TZ enabled, all application runs in secure mode.1) LR = 0xffff_fff9, CONTROL = 1 => BX LR increments the...
Hello,I'm using the STM32H743BIT6 microcontroller in a project, and I'm interested in utilizing USB_OTG for high-speed data transfer to LabVIEW. I've come across some schematics that involve connecting USB_OTG pins to a USB Micro-AB connector. Howev...
How to enable ADC Oversampling and Averaging in STM32L152RC
Hello,I was just shocked to see that H723 and H735 are NOT pin-to-pin compatible, at least in LQFP-144.Shoot, I thought I could switch between H723 / 725 / 733 / 735 if necessary. I found the list for F4 / F7 / H7 compatibility, is there another list...
Hello,I am looking for advice in using an Infineon S27KS0642 64Mb HyperRAM chip on a STM32L4R5Z and configured via CUBE.I have it working, so I am pretty sure that the hardware is connected correctly and I can read and write successfully to it. Howe...
I'm using an STM32H563. Setup to get ADC captures into a buffer using DMA in circular mode.I have TIM1 triggering an ADC1 conversion of two channels. And a buffer with 16 readings using DMA. The GPDMA is set in Standard Request Mode and Circular enab...
Hello,I'm trying to use the PSSI bus in slave mode to transmit data from a small FPGA. After some time chasing a weird bug (I'm losing 8 32bit words at the end of packet) I decided to use a logic analyzer on the bus and it showed a weird behavior fro...
I have used an example code from STM of CAN loopback mode I have used a CAN transreceiver but i'm not getting how to check the signal as well as the data in CAN bus analyser please help me in hardware connection as well as how to check it in CAN bus ...
we r doing one task how to print hello world in mcu boot using stm 32 board . I KNOW THERE IS CONFIGURATION BUT NOT WORK properly we tried. there is one configuration CONFIG_BOOTLOADER_MCUBOOT=y which connect mcu boot code and application code. when...
So table 54 Vih for 5V tolerant pins is 0.7Vdd. For Vdd 3.3V this is 2.31V.I'm having input capture trigger on signals that only reach 1.8V with 100% consistency on 4 pins.Most stm32f4 the Vih for the same pins is 0.45Vdd + 0.3V, which would be 1.65V...
