Hi everyone, I'm using an STM32H755 microcontroller to read 20 temperature sensors (NTC thermistors) via 20 ADC channels for a testing setup. Each thermistor is wired in a simple voltage divider circuit like this: [VCC] -- [NTC] --+-- [Fixed Resistor...
The ref manual (RM0481 page 2585) says: "This circuit has a defined startup time (tSTARTUP specified in the datasheet) during which the behavior of the USB transceiver is not defined.". I searched for USB and tSTARTUP but could not find anything in t...
Referring to RM0444 and DS12232 (referring to STM32G0x1 programming manual and data sheet).In the Low Power section, the RM states that there are five wakeup pins:But in the register section, there is clear mention of WKUP3 (EWUP3 bit in PWR->CR3, WP...
In RM0440, it states that "Generation of a single interrupt request for the DMA1 controller," however looking at the exception vectors indicates that there is a separate interrupt vector for each channel for both DMA 1 and 2. Also the stm32cube libra...
I am currently working on integrating the AFBR-S50 Time-of-Flight sensor with STM32F030CCT6 microcontroller.I have seen that there's an official document and example for AFBR-S50 and STM32F401RE, which includes the whole setup and integration. But I ...
Hello folks,I've been having a weird issue and haven't found anyone else with the same problem, so I figured I'd post here.I have a project for the STM32H735 BLANK. The PCB has an 25 MHz external oscillator (ABM8W-25.0000MHZ-8-D1X-T3) used as the HSE...
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...
