Resolved! stm32H753 vs stm32H733
Hi I just wanted to ask which of the two processors is actually more powerful. The H733 seems faster, but according to Google AI, the H753 offers better performance :). What’s your take on it? Thank youBR

Resolved! STM32H723ZG max ADC data transfer rate
Hi,I'm confused about the maximum data transfer of the STM32H723ZG. The overview says:2×16-bit ADC, up to 3.6 MSPS in 16-bit: up to 18 channels and 7.2 MSPS in double-interleaved modeThen the 'AN5354 - Getting started with the STM32H7 Series MCU 16-...
stm32c0 Spurious retransmission of USB IN packets
Hi,I have the stm32c071 and I am running with TinyUSB 18.0 on it using CDC profile. Seems to work nicely but perhaps one in a 1000 IN transmissions the endpoint is re-activated out of the blue. Can't see that TinyUSB is doing something to make this h...
Resolved! STM32N6 SDRAM reference design?
Greetings,We're a small team designing a board around the STM32N6 and need a large external memory (e.g. 64MB of SDRAM). Due to the complexity of routing and configuring timings I wonder if there exists a reference design for such a circuit, or at le...
Resolved! STM32H755 SPI Slave DMA Issue
Hello, I have been stuck on this issues where I cannot get my SPI slave running on the STM32H755 to successfully do full duplex communication. Right now I want the simplest case to work where the SPI master, also an STM32H755, sends a 16 bit data pay...
Resolved! STM32C071RxTxN PD4 power domain
Hello there, I see in the datasheet for the STM32C071Rx that the version N (with VDDIO) marks PD4 as supplied by the pin VDDIO in the figure 10:But the table 12 doesn't marks it as a pin supplied by VDDIO but VDD instead:Which is true? VDD or VDDIO?T...

Resolved! STM32U5A9J-DK1 USB Device question
I'm attempting to implement a USB MSC Device using the USB_OTG_HS on a STM32U5A9J-DK1. I'm using the STM32CubeMX version 6.14.1 and STM32Cube_FW_U5_V1.7.0 to create a USBX stand-alone (without THREADX) MSC device. The project builds and runs, with su...
