USB VCP Packet Loss with STM32L4R and Windows
Hello, I have an STM32L4R9ZI controller connected to a computer running Windows 10. I have a custom protocol where the computer sends a command and my controller responds. I am using VCP to achieve this. The communication is established and operation...
Resolved! PC3_C as input
I use PC3_C pin as an GPIO_Input, but when i debug it is flickering between 1 and 0 even without any connection to the pin. anyone knows what happened?this is the setup i useGPIO_InitStruct.Pin = Emergency_Pin;GPIO_InitStruct.Mode = GPIO_MODE_INPUT;G...
Resolved! 1.8V Power Supply on STM32H735
Hello, I'm designing a board based on the STM32H735IGK3 microcontroller in which I want to include two HyperBus / OctoSPI memories in multiplexed mode. For this kind of memories there is more avaiblity on 1.8V power supply, but reading the documentat...
Resolved! STM32L4 - are pullups during reset active when RDP level is 2?
Citing from the STM32L431 manual:The debug pins are in AF pull-up/pull-down after reset:• PA15: JTDI in pull-up• PA14: JTCK/SWCLK in pull-down• PA13: JTMS/SWDAT in pull-up• PB4: NJTRST in pull-up• PB3: JTDO in floating state no pull-up/pull-downLet's...
Issues Communicating with MLX90393
I'm currently using a STM32 Nucleo-G071RB, I am trying to connect to a DAC (MCP4725) and also to a MLX90393 both using I2C, the DAC is connecting fine, but I am getting nothing from the MLX90393, has anyone used this device and been able to get anyth...
STM32F2xxx data send/receive stop working after sometime over TCP LWIP
Hi,STM32F2xxx data send/receive stop working after sometime over TCP.Ping also stop at same time and goes into hard fault error.Is it because of any memory or buffer size limitation? in KEY options of LWIP.Please suggest to resolve the issue.
Resolved! STM32G0B1CET6 vs STM32G0B1CET6N
Hi everyone,I am not sure what is the difference between GP and N version of the chip. What I can find in the datasheet is that N version has additional VDDIO2 and VSS pins. If that is the only difference, what changes do these pins bring?Thanks!
Issue with reading PDM data from digital MP34DT06J microphone using SAI
I am currently working on a project that involves reading PDM (Pulse-Density Modulation) data from a digital MP34DT06J microphone and converting it to PCM (Pulse Code Modulation). However, I am encountering difficulties when attempting to read data f...
Use of SPI ADC (AD4131-8) on OctoSPI (in standard SPI Mode) on STM32U585
Hello,is it possible to use octoSPI interface in "normal" (3wire or 4wire) SPI Mode to control and read-out external SPI ADC like AD4131 on STM32U585?I only found information, that memory devices can be used on octoSPI in standard SPI mode.Is this a ...
