Hello, I want to design a PCB with STM32H743VIT6 MCU. But I am not sure how can I choose crystal and capacitors properly. In STM32H743VIT6 datasheet there is one section about this topic;according to this information should I take the Cstray value as...
Hello,I'm new to this STM32 products. We designed custom module with STM32F103CBT6TR. We are facing issue with serial boot loader.I'm using CH340 UART to USB converter module. CH340 MOD TX --> Our Module's RXCH340 MOD RX --> Our Module's TXCH340 MOD ...
From the ES0335 errata there are two errata that look pretty significant for dual bank boot (which I'm planning to use as the basis of field firmware update):2.2.8 Dual-bank boot not working when the boot in flash memory is selected by BOOT0 pinDesc...
I have an I2C device that only operates with 1.8V logic (Pins are not 3.3V tolerant) that I want to connect to the STM32N6. I don't want to add an I2C redriver if I can avoid it. I want to keep as many of my I/O pins on the STM32N6 powered from 3.3...
I am encountering an issue with ADC readings on a custom board based on the STM32H533CET6.Hardware Setup: I have a simple analog filter connected to the ADC input. I have verified the input signal with a multimeter, and it correctly varies from 0V to...
Hello, I’m trying to transmit data at 2.5 Mbps (2500000 baud), but I’m not receiving any output. The same code works correctly at 2 Mbps, so the issue only appears when using 2.5 Mbps.I tested both 64 MHz and 40 MHz clock configurations for the UART....
Both in the manual and in CubeMX, it is shown that my microcontroller, has the ability to configure the FMC, for an asynchronous muxed PSRAM interface.However, in the manual I can only find the timing description for the asynchronous NOR Flash and fo...
I'm trying to drive a display controller and have found it trickier than I anticipated, and I hope you can kindly help. My microcontroller is the STM32U545. My display controller is the UltraChip UC1628c_A, as part of a custom 160x160 monochrome LCD....
Hi allI'm pretty sure this was already a topic, but i haven't found a solution yet. Since i'm a beginner i definitely need some help here.I'm sending UDP data with LWIP and FreeRTOS. It works, but after some (random) time the code gets stuck at co...
Hello,I’m developing a USB composite device on STM32 that combines RNDIS and CDC interfaces.The device works perfectly the first time it’s connected to a Windows 10 PC — both RNDIS and CDC functions operate normally.However, after I reset the MCU or ...
