Issues with PDM mono microphone with I2S
Dear all,I have some trouble setting up the correct acquisition of the MEMS microphone over I2S.Consider the STM32F401RE Nucleo board connected to the IMP34DT05 PDM microphone with L/R to GND.Through Mx, the I2S peripheral is configured as follows:Th...
Resolved! STM32F412 I2C slave that may be required to transmit or receive (non blocking with interrupt) without knowing it first?
On a STM32F412 I need to have an I2C slave that may be required to transmit or receive data without knowing it first.The problem is that we have two separate functions:HAL_I2C_Slave_Receive_IT to receive data from the master, but the driver will hang...
STM32F407VGT6 configuration for PHY LAN8720A using STM32CubeIDE
Hi, i'm using a STM32F407VGT6 mcu and i'm trying to make a basic ethernet connection with the phy 8720A. I set a basic configuration using the STM32CubeIDE with ETH perihperal (without DHCP) and LWIP. Still, i can't get the board respond to a ping.I ...

freemodbus poll question
hello every oneWe are developing a device with LwIP2.1.2 and FreeRTOS.We used Comm Operator to test freemodbus and run an endurance tests with a polling modbus every 0.1 second.but if we use both of them in same time(refresh the web and read data via...
how write hex file in flash, using own bootloader(eg: usb host msc class firmware upgrade)
I am write the bin file in my flash using own bootloader(eg: usb host msc class firmware upgrade) it's working properly without any problem.Same thing i did using hex file it is not working what i do?
Using ADC in interrupt mode, using callback HAL_ADC_ConvCpltCallback() to read values from two channels. But I am getting OVR error.
I place a break point in the callback HAL_ADC_ConvCpltCallback() and the first time it is entered EOC, EOS, OVR are all set. So I have already missed reading a conversion. How are mulitple values read using interrupts. After reading through the doc...
How to integrate uIP stack on stm32?
Hi,I am working on stm32 device which is interfaced to LAN9250 using SPI.i want to integrate the stack(i am not considering the lwIP due to very less RAM available on MC.)Has anyone ported uIP stack on stm devices? i want to send UDP packets from MC ...
I am using stm32f746g discovery board. I am tried "usb host msc class firmware update" I segregate my internal flash, 0x08000000 to 0x0804000 - USB boot application 0x08040000 to 0x0810000 - USER application
Prior to this i am trying to jump the user application from boot application, but it is not working. After change the linker file script in my user application it's working properly.My application run at 0x0804000.Now my problem is everything i am do...
