ES and E marking on NUCLEO-F303RE
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.

Resolved! Is it safe to reuse USB D+/D- (PA11/PA12) as GPIO after one-time DFU programming?
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...
Is a delay required between a write to EXTI_PR and a WFI or WFE instruction?
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...
Resolved! STM32G030F6P6 TSSOP20 crystal oscillator?
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.
STM-U545 - memory allocations?
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...
STM32F030C8 HardFault with 1 bit flipped address access
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, ...
Resolved! How Many G4 FDCAN Peripherals
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?
Resolved! Issue with the display with ILI9341 over SPI
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...
Resolved! Confirm my STM32G070RBT6 SPI1 configuration ?
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.
STM32H503 ADC1 DS14053 Rev 4 vs. RM0492 Rev 3
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...
