@FvM Thanks dear for your response.
I tried the code and it seems ok to me.
The tool which they send me have the same response as of my microcontroller program.
for example if I send command ^P003ID from their tool then the CRC is AB 6D.
and response of microcontroller is also AB 6D
if I send...
Dear @Aussie Susan Thanks for your reply.
Could you tell me how many types of algorithm are there? How to identify this?
I have received the CRC routine from vender side. Could you tell me about this.
INT16U cal_crc_half(INT8U far *pin, INT8U len)
{
INT16U crc;
INT8U da;
INT8U far...
Hi Guys
I am working on some project and want to communicate microcontroller with the device.
Commands will be send through the device.
for example the command I send will be
it will calculate CRC internally and be like that
Here CRC are (AB and m6D).
I want to know how to calculate CRC of...
Hi Guys
I am trying to simulate a simple circuit called Dimmer Circuit. I wrote some lines for PIC16F877A microcontroller. I want to swtich Triac based on microcontroller output. Partially it is working fine. Negative portion of AC source is operating as desired but Positive portion of AC source...
hi
I can see clearly from the PCB that these points are short.
No
Basically i have a damaged 50KW Three Phase On-Grid Inverter and just seeing what is the circuit and how does it works for my knowledge.
I have seen all the circuit and understand it but this portion i am unable to...
OK fine. now the scenario is that i am reverse engineering an circuit, its circuit is something like
The portion which i have marked Red are short. Now how does this works? any idea
Hi Guys
I want to know about the operating of IGBT. Does it is same as i mentioned in diagram or this will not be the scenario
IGBT # is 10-FY12NMA160SH01-M820F18
if not then what would be the flow?
Thanks and best regards
Hi guys
I have made videos of signals going to LCD.
can anyone tell me how to start decoding the signals?
The Blue waveform is at WR pin of LCD and yellow waveform is at DATA pin of LCD.
Thanks
You are right bitwixt its on LCD glass itself. The LCD is being used in UPS that's why it has custom icons. I also want to use it in the same scenario that's why i have choose this LCD.
Hi guys
I have an LCD, see the attached files. I want to interface it with microcontroller, but i don't have its datasheet nor it has any model no or company name. Currently it is connected with some circuit, which is driving it. What i come to know is that it's 3 pins are connected to...
I have buy FRDM-KE02Z freedom kit form freescale. Can anyone give me some sample programs written in keil like blinking an LED as i am new to this platform.
Hi guys,
I want to write programs for micro-controller MKE02Z64LVD4 from freescale..suggest me free compiler for writing programs as i am new to this microcontroller. I programmed PIC microcontrollers using CCS compiler.
