I have two Sainsmart STM-5045 4.5a stepper drivers that i would like to get running, i had a pretty tough day last week with my machine and had to put this aside for a bit but i would like to see if i can salvage either of them today.The order of eve...
Could someone help to understand the better value to use at frequency deviation, considering at bellow specs: #define BASE_FREQUENCY 916000000 //Hz #define MODULATION_SELECT MOD_2GFSK_BT05 #define DATARATE 38...
HiI am developing RF transceiver with S2-LPQTR, frequency range 413-479 MHz. Also I bought BALF-SPI2-02D3 which applies to 433MHz impedance matched balun filter. Based on the mentioned details, I referred to the following schematics for designing the...
Hello,I'm trying to set the voltage to 3.3V on my STEVAL-USBI2CFT adapter, but I'm unclear on how to do this. The user manual (UM3226) mentions setting the voltage via soldering jumper JP4. However, my board has seven solid pads labeled J8, J4, J5, J...
We are using the STUSB4700 in our PD implementation as a source. We have encountered an issue where it seems like the output is constantly switched on/off/on/off with about 500ms on, 200ms off timing.Below is the schematic which connects to a USB typ...
Actually I’m interfacing emmc . when I 'm working with sd card it detects sd card , but when comes to emmc it doesn’t detects emmc card , so how to solve these issues and how to power up this emmc module and emmc doesn’t have card detect pin, so how ...
Good morning,In a university project we are using an nRF24L01 chip to produce a signal, which is then split and modulated by means of other devices.The final stage of each of the split signals is a AD8341 chips which has a 50ohms differential output....
Hello, I am trying to test out my TIMEKEEPERS square wave output. I set my frequency, then enable. However, I do not get a signal out. The SNAPHAT is attached to the IC, so I am not sure what is wrong. Do I need to read after every write, re...
I want to use the WiFi module IDW01M1 and/or IDW04A1. In both quick-Start-Guides I get the tip to download the "X-Cube-WiFi1 expansion software package for STM32Cube". Unfortunately all the Links for this file are broken/dead.Is this package compatib...
Good Morning,I downloaded the zip file for the 2N2907AHR SPICE model, but Windows complains that the folder is empty and cannot be extracted. Can someone else confirm this behavior, and if so would it be possible to post a working copy?Thank you,Jon
