hi, i am trying to implement SNMP v3 using PIC32 with harmony stack of TCPIP. i am getting error of invalid engine ID.
what can be the reason of this error. I am using manage engine MIB brwoser.

hi,
initially i was using 128x128 image(32768 bytes of data). first i stored that in RAM through DMA then transmit it over USART. it works fine.
now i am shifted to 640x480 image. I have data stream of 614400 bytes coming from camera. the RAM did'nt support such a large buffer. image is comming...
thanks. no, i am not using hand shake or flow control. simply STM32F4 transmitting the DATA and PC is receiving it. there is no problem on STM32 side, AS if i would communicate between 2 controllers it will be done exactly on speed i calculated... but with PC it slows down. in matlab same...
hi:
i am interfacing STM32 at 115200 bit per sec baud rate with PC. I have data of 32768 bytes.
32768x (8/115200) =2.27
theoretically data should transmit in 3 sec approx at MAX. but I have received data in 2 to 3 min...
1-why is that so?
I also interface with matlab. but same...
hi:
I am interfacing 7670 to PIC. and I have got data in two formats yuv422, rgb565. after reconstructing image in matlab but i didn't get good image. i have attached image and text data file... is there problem with my reconstruction or with the data?
thanks
Hello:
i am using ov7690 with at91sam usin MCK at 12.3MHz. but for testing purpose i am using I2C at 153KHz from atmega2560 for SCCB. I can read anyregister from ov7690 but I can't write to any register. the response iscorrect i.e. status register of TWI of atmega2560 depicts correcr...
hi;
i want to send data over GPRS between two GSM based WSN nodes. what would be the way of doing that? DO i need a server?
please refer me to GOOD data. {its like communicating between two mobiles over GPRS , how would i do it?}
Hi;
I am interfacing SAMBA (GSM Device with USB interface and audio in/out) with PC. I want to receive audio from SAMBA.
1- I made the audio output of SAMBA as input to PC MIC. But when I receive audio it is noisy.
2- But when I listen audio output directly from head phone it is clean...
hi:
i AM using SBC with xlinux. i attach PS2 keyboard and check all the signals waveforms. on the basis of that i have devloped avr based keyboard. so that i can send commands from my avr through PS2. all is well.
But the issue is after some time PS2 of SBc freez even if attache original...
hi
i have used SPI on atmega16 with sd-card and it works fine. now i am shifted to 2560. the MASTER_INIT() function as describe in datasheet of 2560 , i used the same function. when i SIMULATE the code in avr-studio, the SPE ,MSTR and SPR0 is set. but as soon as program cursor step out side the...
HEllo:
wat will happened if external interrupt occurs during I2C Or SPI comunication with slave device?
for example my program is in the I2C communication with RTC or EEPROM and in mean time an external interrupt occurs and i consume 10 clock cycle in ISR, then what will happened to I2C...
