I have design pcb for Stm32H723VGT6 ( 100 pins TQFP ) my job is read adc 12 bit and transfer over usb to PC . i have set sysclk to 550 MHz and ADC clock to 64 MHz so i got sample rate to 1.3 Msps but mcu are hot. So i have sysclk to 400 and ADC ...
I am working with STM32 U575/U5A5 and L4 series of STM32 controllers in low power mode. I have programmed the controller to wake for every 10s and blink LED. This issue what we observed is once immediately flashing hex file to controller using STlin...
Good morning,In regards to the current limit placed on the PC13-PC15 pins of the STM32G431VBx3 that is used as the basis of the STSPIN32G4 (and whose datasheet is referred to multiple times in the STSPIN's), the '431 datasheet has the usual low-power...
I have a system of sensors connected to an STM32 chip, all working via I2C and 3.3V.I've created interface libraries for my sensors, specifically the temperature and accelerometer ones. However, when I read the values measured by the sensors, I came ...
Hi AllMaximum input voltage for this series of MCU per Table II of the datasheet is specified to be 4.0 VDC for all pins other than five-volt tolerant. Table 12 specifies the maximum injected current for all pins other than five-volt tolerant to be +...
Hi,I have two MCU communicating with each other via RS485. It's a very simple code one MCU send a data to other and the other is trying to receive this. With MCU2 code everything is fine. It sends data like it should be.Problem is with MCU1 code. Whe...
Hi All,I recently set up a USB CDC application for the first time, using a STM32G431 device.While writing the software (on both Host and Device), I had some problems. Firstwith achieving the expected throughput, then with corrupted (or so it seemed) ...
hello, I have a display configured for FMC but I would like to add a framebuffer to the RAM memory, unfortunately the MCU memory is not enough (the display resolution is 480x800) so I have to add external RAM. My question is how to do it since I am a...
Hello,After reading the following threads:How to program STM32 Option Bytes with the HAL API - STMicroelectronics CommunityWhat are option bytes in STM32 and how do I use th... - STMicroelectronics CommunityProblem with option bytes set from program ...
Hi, I am currently using STM32H5 series, to transmit the RTC register content to an escalator base board. I need to transmit these data in a parallel manner (i.e. MCU act as a slave and the base board act as a master). I studied that STM32H5 seri...
