I am attempting to display to an ILI9881C based panel. After successfully initialising and testing the panel using DSI only, I am working on DSI Video mode to pull data from a frame buffer via LTDC.I have the DSI configured as follows static void MX...
I like to use SPI in continous DMA mode together with a SPI-slave that uses the falling-edge of the spi clock (AS5048A: https://ams-osram.com/products/sensor-solutions/position-sensors/ams-as5048a-high-resolution-position-sensor). So, I have to use C...
Hello, I'm using Nucleo H723ZG.In my project, i need to detect a rising edge to trigger a callback. What i have done is that i setup a GPIO as external interrupt, and i verified the code by manually connecting and releasing from 3v3 pin. The actual s...
Split from this thread. Thank you for your previous responses and guidance. We are now planning to move to the STM32H750XBH6 (BGA package) with a 32-bit SDRAM (IS42S32400J-6TLSDRAM ) interface in our custom board design.Our project uses a 12.1-inch d...
Hello stm community. I am working on a project involving STM32H7 series MCU with Raw LCD panel of 24 bits. Since the display has no IC i am using the internal LTDC component to drive the lcd. So i have some questions can i drive the lcd backlight wit...
I'm bringing up a design based off the STM32H573 and I believe I'm having a number of issues that are probably sharing a common thread with bad hardware. I don't usually screw those things up, but I guess I got unlucky this time.1) PC1 when configure...
Hello,another day, another N6 "issue" :)I want to do RAM to RAM copy by HPDMA, but the data never get copied from Src to Dest, Dest always stays unmodified. I have checked the 'DMA_RAMToRAM' example for N6 and went from there, but with no success.DMA...
I'm looking for an ST microcontroller that can do I2S receiving while remaining low power, presumably by keeping the core asleep and using DMA to copy I2S chunks to a buffer. I think I saw a video demo of this at some point somewhere on the website, ...
When using SPI6 in Slave mode with TX DMA in Circular mode, the SPI FIFO is not updated with data from the DMA buffer for the first SPI FIFO size (8 bytes). Both the SPI Master and SPI Slave were debugged: The SPI Master transmits one frame. On ...
Hi all,Im using STM32F410 uart 1 to transmit and receive.I use DMA to transmit bytes. I then use TC interrupt to send a break,then push an event to an event queue to signal that the transmitter is free.void interface_uart_tx_eot_isr(if_uart_t* p) { ...
