Resolved! How to configure "Delay between 2 sampling phases" on the STM32G431
板：STM32G431 NUCLEO-64我的目标是在 ADC1 和 ADC2 上实现 4 MSPS 的采样率。通过使用交错采样，我的目标是获得 8 MSPS 的有效采样率。虽然我知道这可能与数据表中针对多通道 ADC作的声明限制不严格一致，但我相信这种差异与我遇到的问题没有直接关系。根据数据表中的图1、ADC 时钟应低于 52 MHz。图 1在我的设置中，我在交错模式下使用 TIM + DMA + ADC，配置如下：定时器触发频率：4 MHzADC 分辨率：12 位ADC 时钟：60 MHz采...
DSI issues driving a SN65DSI86
Dear forum mmebers,I am trying to use an STM32U5G9 MCU to drive a Ti SN65DSI86 DSI to eDP converter with no success.Previously I have evaluated the SN65DSI86 with a Xilinx FPGA as a DSI source where it was working perfectly from 640x480 to 1920x1200 ...
Resolved! STM32F769 VDDUSB
Hello,I'm using in my projects with ports PA10,PA11 (for Logs - uart), and PB14 and PB15 as normal GPIO.They didn't works.After long troubleshooting.... I found out that is because these ports are supply separately by the VDDUSB pin which was disconn...
I2C slave action to depend on 1st byte of unspecified-length message
I2C slave that needs to act differently depending on the first written byte in a write request with unspecified length [1 or 3 bytes]Hi!I am trying to emulate MCU master to I2C slave devices using two "black-pill" MCUs (STM32F411CEU6 @100MHz) and ST...
How to Achieve 0.1 Hz Resolution from 0 to 10 kHz Using STM32 Timer?
Hi everyone,I'm trying to generate output frequencies from 0 Hz to 10,000 Hz using STM32F407VET6 with Timer2 in Output Compare Toggle Mode. The timer clock is 84 MHz.I need to achieve:0.1 Hz resolution up to 10 kHzIdeally, also support 0.001 Hz reso...
Resolved! STM32L031 noisy, even in reset - EDIT: it's not the STM32
EDIT: it's not the STM32, see latest postHeyho,I have some custom miniature PCBs here, the unholy combination of a super-high-impedance-low-noise amplifier (going to a low noise audio input with 24bit ADC, spectra below from that one) and a STM32L031...
ADC Configured 5 channels but when iam commented 4 reading only one, then iam getting incorrect values
iam using STM32L051K8T6 Below attaching the code
Resolved! The program enters HardFault _ Handler, but no valid stack information can be found
Hello, my program runs to the HardFault _ Handler function, I usually use interrupt check whether there is a function variable overflow, but this time the jump function is irregular, I do not know how to judge, please help me, I will provide the rele...
The LPBAM scenario fails to be created after the HAL update.
Hi everyone,We're experiencing an issue with LPBAM after the latest HAL update. We initially reported the problem on the STMicroelectronics GitHub , but after two weeks without any response or activity, we decided to seek help here.In the following ...
