I am using STM32F051K6U7 HAL_GetTick()

Hi ,I am using STM32F051K6U7 for one of our project.For Timing the HAL_GetTick() is low accuracy .every 240 seconds there are 1 to 2 seconds off .I am using a f0discovery board, so I am using internal RC occilator. Is this expected or is there an er...

Someone has ported the libtwolame or other MP2 encoder library to STM32 series?

My idea is to use the I2S input and encoder a stereo pair in MP2. Someone have successfully ported the libtwolame (or other MP2 encoding library)? The STM32F4 or F7 CPU is fast enougth to accomplish this task?

How to send ATR commands in STM32L0x?

I have connected ISO 7816 to my STm32L011G4u7. I am new to programming. Can you please temm me how to initialize smart card and send the ATR commands?

aci_gatt_update_char_value returns undocumented error code

Modified the BLE_Throughput example to use indication characteristics instead of the notification.I also set the interval to 1 second for debugging purposes because I saw that only 1 IND is read by the client per connection interval.I see that SendDa...

Maximum frequency of DAC's external trigger

Hello, my NUCLEO-H723ZG is running at 550 MHz and using maximum 137.5 MHz TIM for DAC triggering but I want triggering faster than this so, can I use external clk with frequency more than 137.5 MHz?

Filtering after DAC Output

Hello, my DAC can output various of symbol rate from 100ksps - 2 Mbps then I want to filter the signal at the output for removing the steps. Which filter should I consider (maybe tunable filter?), Is there any better way to do this?

Help with understanding pin layout for stm32f030f4p6.

Hello, we are college students from the University of Texas at Tyler and are looking for help in furthering our understanding the functions of each of the pins in a stm32f030f4p6 microcontroller. We intend to use this as the microcontroller to develo...

stm32g031 problem DMAMUX module

Good afternoon!I have a problem with the operation of the DMAMUX module with synchronization from EXTI on STM32G031.my task is as follows:1) start reading SPI data after receiving EXTI event.2) after SPI data reading is finished, start sending data v...

STM32 CAN-FD

Hello,I have no CAN experience, but I have to decide soon if we can use the STM32 (prob. H7) with its CAN-FD interface.To me with my limited CAN knowledge it looks like it supports all hardware necessities, like "old & slow" CAN and the newer, faster...

I am designing hardware using STM32H7. I would like to connect three power monitor devices to SPI4 of MCU as slave devices, but SPI4 has only one NSS(slave select) pin. How should I connect these multi slave devices to SPI4 of MCU?
