We are using an STM32G491 with TDM audio output active on SAI. When activating the 4 MHz bit-clock on SAI1_SCK_A, Vref and temperature measurement become very noisy, while externally connected ADC inputs are not affected.See attached graph for differ...
Hello every body, It is my first post and I´m newvy with this tecnology. I'm trying to read from adc 1, 2 and 3 values from the DMA (in case of use adc 1 and 2) and the BDMA (case adc3). In the two first cases, the interrupts are generated correctly ...
Hi,A customer is in the process of sending to manufacture a 5V, 15 segments and 8 planes, custom LCD. I wonder whether the STM32L073 mcu is going to be capable of driving such display. Put it in other words: whether 3.3V is going to be good enough fo...
The STM32H573I-DK is now available for order! It is the first kit to support Secure Manager, a turnkey system-on-chip that integrates core security services certified and maintained by ST. The STM32H573I-DK enables developers to explore all the integ...
Hello I have been asked how difficult it will be to create a custom bootloader for the STM32F105.We are for some reason using the 64 pin version of the chip and from the AN2606 i can see """""Workaround• For 64-pin packagesNone. The bootloader cannot...
Hi,We are using the STM32H725VGH6 MCU and are plannign to use the internal SMPS for VCORE.With regards to the connections required for the VLXSMPS pin, I would just like to confirm that a 220pF capacitor is required on this pin in the "Direct SMPS Su...
ADC analog bandwidth tests:--board nucleo-G474re, on-board voltage reference.--sampling rate 2.8 msps, free-run mode, 12-bits, --156 kHz & 19.47 MHz. Approximately at 19 MHz ADC has ENOB < 6 bits, limiting factor seems to be aperture jitter about 12...
Hi, I'm using an STM32F401RE board for a class(programming using MacOS). Right now, I'm using VSCode and make to edit and compile my code, then using stlink to flash it. Now, I'm trying to communicate with an MPU6050 using I2C; however, when I run HA...
Hi all,I am working on a research project for my school that involves me programming a microcontroller, however, the program that I most recently flashed to my board causes the processor to quickly heat up and cause a burning smell. I am unsure if th...
Hi, I designed PCB including STM32F103CBT6 and I have attached schematic here as a reference. I am using SWD with an adapter from (Olimex LTD / ARM-JTAG-20-10) then connect through ST-LINK/VE debugger. After checking all voltage rails on the board, I...
