I have an ADC connected to my MCU using I2S. MCU configured in I2S master receive mode. MCU supplying the ADC with 12MHZ MCLK. MCU sampling freq is 48 KHZ(Actual is 46.875 KHZ), Number of slots are 4, Data size is 16bits and I2S standard protocol. Us...
I try to figure out what the correct UCPD clock frequency is.RM0456 in section 74.4.2 UCPD reset and clocks states:"The receiver is designed to work in the clock frequency range from 6 to 18 MHz. However, the optimum performance is ensured in the ran...
STM32L4R9AII6 generates 16 SPI clock pulses when I have selected data size 8 in STM32CubeMX.When I measure the SPI clock when I write a single byte to the SPI1 DR register it outputs 16 clocks.When I debug I can look at the SPI1 registers. The CR2 DS...
Hi guys, Can anyone list out a few steps which need to be followed for bare-metal code generation of using Timer in DMA for PWM generation. Thanks!
Hello,some of our boards do not boot after powering them. We realised that most of the time this happens, the 1.2V at VCAP1 and VCAP2 == 0V. At our boards the BYPASS_REG pin is floating. So there are two questions for us now:1. Could the floating BYP...
I have one of these:NUCLEO-F207ZG - STM32 Nucleo-144 development board with STM32F207ZG MCU, supports Arduino, ST Zio and morpho connectivity - STMicroelectronicsI am wanting to find some example projects with Cube setups for ethernet. Are they out t...
I need to capture 8 x RS422 data and send them to abother unit via TCP/IP. We have designed a custom board for this. My questions are: 1. In terms of software programming side there is no difference between RS232 and RS422 right?2. Which example samp...
I see this: (on NUCLEO-H563ZI board) JTAG chain detection found 2 devices: #0 Id: 0x6BA00477, IRLen: 04, CoreSight JTAG-DP #1 Id: 0x06484041, IRLen: 05, Unknown device What is the device #1 ?
Hi,I using Eval boar : stm3210E-eval (stm32F103ZG6)I want to communicate with an external device vua USB, this device should be communicatre with USB1 gen,I ask if it could be with this eval board?>If not, if I use this MCU stm32f103ZG6 and make a pr...
Hello,I have a test app that starts in wake for 5s (with "high" current and GPIO output high) then enters STOP Mode 2 (with "low" current and GPIO output low). It remains in that mode until the EXTI 1 interrupt is triggered by a button press, which w...
