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...
hello everyone im working with stm32f4 nucloe board , i want to implement one wire communication to send data to a microphone but also i need a clock above 40khz to send this data for that im using two timer in master slave mode , one for generating ...
I have written a code for TI above model sensor interfacing with F401RE. Code not working. Pls help me to correct this code.
Hi.I have a big buffer with Chirp data for testing that about 30000 of int16 length and I can not get right result from FMAC IIR filtering operation. The operation configured in polling for read and write.I calculate a bandpass IIR DF1 filter coeff w...
Hello!In my project I'm using STM32L476VCT6. I don't want to connect external voltage reference, only internal. Could I leave floating pins VREF- and VREF +? I saw in the datasheet that these pins could be tied internally to Vdda and Vssa correspond...
