LVDS display interacting with STM32 LTDC
I am trying to interface a 7" LCD-TFT screen that uses LVDS for its interface. I was wondering if the LTDC on the STM32F439 or STM32F469 could be used with the LVDS interface?

MISRA compliance report needed
Hi ST, Can I request the MISRA compliance report for STM32H747? Or where can we download the relevant document? Thank you.
Resolved! STM32H723VG SPI TransmitReceive sometimes works and sometimes does not, based on Delay length
Hello,I have developed my own board using the STM32H723VG and two equal sensors connected separately via SPI1 and SPI2.I have underclocked the MCU to 300MHz. The SPI clock is 48MHz while the communication frequency for both sensors is 24MHz. As CS I ...
How do I set the NUCLEO-L476 to Low power mode
I need to use the energy collection mode of ST25 to wake up L4. The software used now is En.X-Cub-NFC7. How can I modify the example code to set L4 to low power mode and wake up L4 only through the energy of ST25?
Resolved! Uart receiver pb
i have established communication with a BLDC (Brushless DC) controller. Initially, i send a message to the controller using the function void sendParameter(uint8_t parameter). Following this transmission, the BLDC controller is expected to respond w...
Resolved! NUCLEO-144 H723ZG "Can not connect to the target!"
Hi there,I received a new out of the box NUCLEO-144 H723ZG board which I can not connect, but getting the "Can not connect to the target!" message (see below)What I've done so far:- checked the Jumper as described in user manual UM2407 section 5 >> a...
Resolved! NUCLEO F411RE, interrupt preemption priority is not available.
I am trying to set up a multichannel ADC and following YouTube tutorials to create it. However, the STM32 IDE will not allow me to set preemption priority to 1. Similarly, I cannot set the clock prescaler as divided by 2. I need to make a multichann...
Resolved! Where are the schematics for NUCLEO-H743ZI2
Hello,I have here two Nucleos with an H743 on it. If it is rev Y, it is the "old" 144pin Nucleo board with the break-off ST-link board on top. For this there is a schematics in appendix A of the user manual. But if it is rev V, it is NUCLEO-H743ZI2 ,...
stm32 dma request synchronization settings
Hi,I have an external SPI 8 channel ADC which is connected to the STM32,one of timers would generate a 32KHz 50% pwm signal which is connected to the ADC convert pin, the ADC has a busy pin which is connected to the EXTI0 of the MCU.The plan is to us...
Resolved! STM32H743 - ADC wrong sampling rate
Hi STM32-Community, I'm using an STM32H743 with ADC3 in circular DMA mode. ADC has a clockfrequency of 48 MHz. I'm using 8 channels within this ADC3 and also configured the DMA with said channels each with a sampling time of 64.5 cyles. I'm using an ...
