Hi,My customer wants to design a high speed ADC aquisition system with minimum 100 MSPS rate and 14-bit resolution.The external ADC devices like AD9258 and AD9268 have this capability, which we are proposing.Would it be possible to use a high speed S...
Hi,we would like to add live video playing/streaming to an STM32-based board we are designing that uses MIPI-DSI to drive a touch display, and we are at the stage of choosing the micro.Ideally it would stream from HDMI signal but we can use another i...
I'm working on a custom board with a STM32H723ZG. I'm also using external sd ram part IS42S16400J-6TL found here (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS42S16400J-6TL/2708625). I've followed the excellent s...
Hi,I am using STM32H725REV6 chip in our product. Based on my understanding, since this is 68pin version which doesn't have VREF+ pin, the VREF+ is internally connected to VDDA. If my understanding is correct, I would like to ask if we would like to u...
HiI have implemented ADC1 on a DMA and verified its operation. I then implemented the ethernet stack and verified that it can be pinged. The issue I'm having is that the ADC DMA stops working once the ethernet stack is implemented. I believe the erro...
I have three variables:volatile uint16_t a[20000];volatile uint16_t b[20000];volatile uint16_t c[20000]; However, I only have one DMA channel.Can I use the DMA to transfer these three variables together in circular mode?starting with the first 10,00...
Hi I am using a STM32L433 and have a digital input pin, which is checked on bootup and enables the USB if 3.3v is in the pin. When working in debug mode, it always works, but when I switch to release mode , using stm32CubeIDE , it always reads 0v,...
I used a Nucleo F767ZI dev board to check and write firmware(The IC on the board is STM32F767ZIT6U with the other characters being AA 254 VQ Z on first line and TWN AA 341 on line 2),when I use HSI clock I am able to operate PD7, PG9, PG10, PG11, PG1...
We're running into a really weird situation with a bootloader that copies some code into ITCM. The bootloader initializes various peripherals and clocks and then copies data from the QSPI flash to both the SRAM and to the ITCM memory. Then we use t...
HelloWe are using STM32H563VIT6 in our project. When the PCB was designed, our design team used PB13 and PB14 as TXD1 and TX_EN pins (from what I know, they were using CubeMX when designing the board). When I have started working on the board I was u...
