We are using STM32H743 and STM32H745 in our product lines and embedded bootloader is used for boot loading. The PB14 pins is used as Debug Uart on USART1. The PA9 pin is left unconnected. Its Not Connected pin. Is there any impact on this upgrade. ...
I am using NUCLEO-F303RE board. I couldn't find ES and E marking in the product information of the datasheet. Does it mean it is not "ES" and "E" marked. can any one please confirm it.
Hi, I'm using the STM32C071K8U6's built-in USB DFU bootloader for one-time production programming. After flashing, PA11/PA12 (USB D+/D-) are used as regular GPIO outputs to control two P-MOSFETs (each with their 100kΩ gate pull-ups to 4.2V). The US...
I am writing code for a system where a STM32F1 communicates with the 8-bit data bus of another CPU (a 65C816). The STM32's GPIO pins are presented to this CPU as memory-mapped registers via a set of latches and bus transceivers. When the CPU attempts...
As I understand, the TSSOP20 version needs an external oscillator instead of a 8MHz crystal connected directly to the MCU pins. Is that correct?I'm asking because I have seen a board on AliExpress using this same processor with a 8MHz crystal.
Building a very interesting platform on U545. It requires Trustzone, will provide PKI stuff, lets see,I.e. ML-DSA stuff.We are so far able to allocate only up to 80kb to the secure world (Trust Zone). Anything over, it bombs.How we get past that? //H...
Hello Everyone,During the operation of my program, there will be an issue of address inversion on stm32f030c8.It occurs approximately every 4 hours, and then it transitions to a "hard fault".For example, I was trying to read from address 0x20000940, ...
G4 ref man says there is 1 (one) FDCAN peripheral:Yet when editing the IOC file I see 2 (two) FDCAN peripherals:I believe the ref man. What's with the IOC file editor?
Hello, ich set up my project with CubeMX for a CAN-FD (1 MBit/s / 4,8 MBit/s) and a Display for communication. Now i have the problem, that the SCK Signal for the communication looks more like a sawtooth signal than a rectangle. Also the SPI-Presca...
