I have a 3byte unique ID number for chip. I want to read this unique chip number and convert it to 2byte and assign this same chip a new 2Byte ID. I know that it is not logical to fit 3byte info in 2 byte, but I want to know if any mathematical way available where I can convert most 3byte...
Hello,
I am trying to design a simple regulator circuit using LM5576
Datasheet Link : Link
Input : 12 to 60V
Output : 12V
Nominal Current : 0.5A (I am using 5576 because 5574 or 5575 not in stock)
Ripple current : 100~200mA
It has a COMP pin. connected to output of error amplifier. Can some...
int main has nothing to do with this.
I suggest you replace the char pointer with float pointer and run the program and see what does not work.
We can help you if you have clear problem statement.
I believe you want to read data from sensor which output values serially at the rate of 600kbps. If this is the case, you should be able to configure your micro to receive serially at this baudrate. Your micro tm4c supports upto 10Mbps.
However to visualize the data on a PC, you will need a...
Hi
Thanks everyone for suggestions. Here are my updates. Today partial solution is found.
1. The culprit was D2 and D3 gate diodes. While testing I removed these and suddenly the noise on 3.3V line shown in my image in #1 is gone and controller no longer resets and works fine. I have no idea...
Hello,
I am designing a battery discharger that can discharge upto 200A on 100V. I want to allow user to configure discharge current configurable using pushbutton and LCD.
Here is my plan:
I plan to use tube resistors of 1200W,10ohm each in parallel so that for 100V it is capable to dissipate...
I guess this error might be due to the fact that the HAL_UART_Receive_IT function takes pointer to non-volatile variable. The error/warning might get resolved by using cast
HAL_UART_Receive_IT(&huart2, (uint8_t*)&inData, 1);
that's good. But personally I would always use volatile as in future...
Hi,
As @FvM mentioned, you can just pass address of a uint8_t variable as shown below:
volatile uint8_t inData; /*make sure this is a global volatile variable, as the address of this variable will be used in ISR*/
HAL_UART_Receive_IT(&huart2, &inData, 1);
Also I hope you know how to use these...
I am designing RS232 communication chip using SP3232 chip
Datasheet - SP3232
Datasheet typical circuit is as below :
I am having question about the capacitor used. These are all electrolytic. Why?
When I googled for example ciruits I found it is being used both ways polarised and...
Hello,
I am very new to audio processing & I want to understand how does the audio communication work in high rise buildings?
Let's say I want to build a system which puts a microphone and a speaker in each floor of a 100-floor high rise buiding, and one central microphone, speaker at a...
Hello,
One of my customer asks a lot of question about current and voltage passing through individual components in the schematic. This causes me a lot of problem when working on a new project and have to change the schematic more than 3-4 times. Because every-time I change a component/topolgy...
