In the RM for the H743 there is little information about using IO cell compensation aimed at reducing noise on VDD and EMI radiated.Posts show the following calls to active:-__HAL_RCC_CSI_ENABLE();__HAL_RCC_SYSCFG_CLK_ENABLE();HAL_EnableCompensationC...
Hi, I am evaluating the STM32H7R7Z8J6, intended to working with a TFT-LCD which is working in parallel RGB interface with DE mode only. The HSYNC and VSYNC signals are not connected. Both AN4861 (Introduction to LCD-TFT display controller (LTDC) on S...
Hi everyone,I am working on an STM32H7A3ZI and I'm trying to to exchange audio data with an SGTL5000 audio codec. Because i want to both send and receive data from the codec i configured the I2S peripheral on the STM32 to Full-Duplex Master mode in C...
Sorry, I'm very new to microcontrollers in general and was wondering if I would need more SRAM or if I could successfully just write to the display driver's memory and not worry about a big frame buffer. I hope to use LVGL to control a 320x240 16 bit...
Hi all! AGENDA: Need to verify the external QSPI flash (AT25Q128A) all sectors Write, Read and Comparing with STM32L496ZG-P using driver code. APPROACH: For write, I am have created a buffer which comprises of page size of 256, and I am using two "fo...
Hi, Please help me sort this out.I am trying to port a custom bootloader originally written for the SAMD21 Arm chip to the STM32U385VGT6. We are upgrading our current product with an STM32 Chip. I am having problems with switching from the bootloader...
I have a problem I can't solve.In a previous project, I used an STM32L4A6 and set the PC8 and PC9 lines high before entering the system bootloader. After starting the system bootloader, these lines remained high. They were used to maintain power to t...
Apologies if this is the wrong group for this query. I have implemented a library from scratch which performs the host side of a DFU upgrade (avoids the dependencies in CubeProgrammer_API.dll, for which I could not find source). The code works just f...
The Raspberry Pi Pico 2W is a dual-core Cortex-M33 processor. It has 16 DMA channels per bus. While I'm not sure if the exact number represents all DMA channels, there's only one path each for the master and slave. Therefore, if three modules occupy ...
Hello everyone,I’m facing an issue with an STM32L4-based design where the USB FS Device stack (CDC) sporadically fails to start correctly. Maybe someone has seen similar behavior or can point me to potential root causes. System overview / setupMCU: S...
