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...
Hello. Please check if there are any issues with the settings as shown below. PB4 : SPI1_miso PB3 : SPI1_sck PD6 : SPI1_mosi Thank you.
There seems to be a documentation error between DS14053 Rev 4 and RM0492 Rev 3. In the data sheet, section 3.17, table 3, "ADC Features" we see a different set of features compared to the reference manual, section 19.3, table 107. The data sheet cl...
STM32H743VGT6 how to use slave I2C+DMACurrently, this usage is fine. However, when using the DMA function, it will trigger an ER interrupt.HAL_I2C_Slave_Seq_Receive_DMA, How to use it? Are there any examples?// 从机地址匹配回调函数 void HAL_I2C_AddrCallback(I2...
