I’m using an analog camera with a CVBS output connected to an ADV7280/TVP5150, which interfaces with the DCMI on the STM32H747. However, the LCD display is not showing any image. Previously, I used the OV5640 camera, and it worked fine. void CAM_DMA2...
I get the following error when trying to debug an STM32H757 with SWO enabled. Failed to enable SWV configuration.Failed to execute MI command:-data-write-memory 0x5c003010 x 4 0x77etc...It would seem the debugger (ST-link v2) is not able to read the ...
We want to use the SDADC to measure the temperature of a PT100 sensor. The measurement should have a very high accuracy of +-0.5Kelvin. Therefore, it is important to have a low offset error. The datasheet lists very large values for single-ended mo...
Hi,What I want to implement is to receive the Input Trigger (called Ch1) signal on the rising edge in One Pulse Mode and output a PWM signal through Ch2. At the same time, I want to capture an ICP interrupt on both the rising and falling edges of Ch1...
Hi, I am using STM32L4R9ZIJ6 with power pin connections as following image.On the same design where VREF+ pin is connected to P3V3, if I configure Vrefbuffer for ADC measurements & use Vrefbuf as 2.5V, I observe that current draw from P3V3 goes from ...
Spent two days of trying to see printf via USART1 from U585 and U575 boards. Was trying to load BLE via DFU on B-U585 and get it work but USART1 became silent. (Wrote separate post on B-U585I-IOT2A as documentation nightmare). Problem: USB-C + STLIN...
Hello, I'm working on finding the smallest possible power solution for the STM32N6. The reference boards(STM32N6570-DK and STM32N6 Nucleo-144) uses multiple discrete buck converters and LDO to power the N6. It must be possible to do it smaller. From ...
I’m performing low-power consumption tests using the NUCLEO-U545RE-Q development board. However, after entering STOP2 mode, I observed that the current consumption remains around 23 µA, which is significantly higher than the typical values stated in ...
In the Datasheet, Table 16 specifies TJMAX as 150 °C, but Table 17 indicates the TJ range as -40~130 °C, which one should I refer to?Table 16. Thermal characteristicsSymbol Ratings Value UnitTSTG Storage temperature range –65 to +150 °CTJ Maximum ju...
Hello, I've just received my custom PCB with an STM32H743VIT6 MCU. It has a Samsung eMMC connected to the SDMMC1 interface (MMC 8 Bits Wide Bus) : (I'll link the eMMC datasheet below.) I'm encountering some issues while initializing the device with ...
