I have bought one board from Ti which is a launchXL F28379D delfino board. I have gone through several videos from TI's tutorial to YouTube videos, but matter of fact all the references are not streamlined enough to make sense altogether. Is there any book that is similar to Mohammad Ali...
Dear learners,
Can someone guide a step-by-step method to get started working on TI uC like TMS320F28xxx series of controllers as a beginner, I find it a little difficult to understand the way I need to create a blank project adding libraries and start to use those libraries to work on my...
Can anyone suggest a few reference manuals to understand the in-depth Embedded File system and FAT and Network protocols? It would be a great help.
Thank you.
I agree, but the problem is I cannot dig inside the fopen or any other file APIs, I think Keil itself is restricting the action. I can only get the return code. And also have no idea how these file APIs are pointing to the drivers. The File configuration file itself doesn't provide sufficient...
Yes, the return values of the function are given bellow as an example
FILE *myfile;
myfile = fopen("xyz.txt","w");
Here the myfile is giving NULL.
And while I am not able to open any file, it going to Hard fault while using read or write instruction.
When I use mkdir to create a directory...
Hello everyone,
I am trying to program lpc4357 for filesystem management. I am using mcb4300 development board for programming. And I am using drivers provided by keil. When used the example code for microSD card it is working fine. when I am changing the configuration for NOR memory, the...
I had used 9-35V to 5V isolated buck converter where I have isolated the ground. And 11.1V to 12V isolated power supply. Both are by mornsun. But still not working. Getting same fluctuation.
Hi, I have observed some voltage fluctuations in the power side, when the Green Led of RPI fluctuate there is a voltage minor voltage drop of around 0.5V max and the it is frequently happening. I have put one 1000uF cap, but not able to reduce the voltage fluctuations. The noise is at audible...

Hi Barry, the shield is there at microphone cable and I have extended that shield till the input of microphone. And shield is connected to ground of microphone and negative terminal of battery.

Hi Andre, I am not using any digital filter. I have used completely analog circuit...
Hi Barry,
I have tried the ground part, that is connecting both the Audio ground and RPi ground to Battery negative(-). But same noise is coming.
In the oscilloscope, the power I have checked across the battery. It is smooth.
Ferrite bead I don't have right now. But can you tell me what is...
Hello everyone,
I have a doubt regarding power line noise in my audio. The audio circuit and Raspberry Pi are power by Li-ion battery pack of 11.1V
I am using 5V buck converter to power RPi and 11.1V for audio circuit. When I power ON the system, I have observed that RPi when starts the noise...
Hello everyone,
There is one issue, when I connect a system of having Ethernet interface to a router and when pinged from a pc it is working fine. But when other devices in the network is turned ON the ping of my device goes down and some time fails to ping(request time out). The router is...
Thanks for the response. I found the problem which was in the software only. Since it was a internal EEPROM so I have seen just the power supply and oscillator connection on hardware. The issue in software was setting up the clock for eeprom. The calculations was based on 375kHz and according to...
