I want to use MODBUS TCP in UC3A1256[AVR32] using FREE RTOS.. Is there any sample code available for that, if it is available and also how to port
with FREE RTOS..
I have worked with TCP/IP with LWIP in AVR32 [UC3A1256] using FREE RTOS. Is there any way to implement MODBUS TCP in LWIP using...
Its better to use timer to produce delay... Run timer for 50 micosec and keep one variable then increment that variable in ISR 19 times, Then set one flag....
As for as LEDs are concerned two things you have to notice it...
1) Minimum Biasing Voltage
RED colour LED [R] -> 1V
GREEN colour LED [G] -> 1.2V
YELLOW colour LED [Y] -> 1.5V
2) Current Rating
For Normal LED [Translucent] -> 10mA...
Two boards i was facing the same problem... I was setting my fuse as internal Rc oscillator [8MHz] then unfortunately i changed into External crystal oscillator [8MHz]... Actually my board doesn't have external crystal for controller... Then i connected external crystal afterwards controller got...
UC3A [32-bit] series from AVR have ethernet and UART... I was using UC3A1512 for UART to Ethernet project... It supports FREE RTOS too... Lot of sample codes and [drivers] Library files are freely available..
some Serial to Ethernet converter is also readily available in the market...
Serial...
Re: RFID embedded system
Its better to start with LF [125kHz] module... HTRC110 [Hitag reader chip] and any one basic controller is enough... Manchester Decoding is required to read the Tag... So, study about manchester decoding [For LF]...
For all RFID [LF, HF, Hitag-s, Mifare, Scosta]...
I am using AVRISPmkII programmer for ATMEGA168... I used to program many times, it was working fine.. But suddenly its started giving problem like this [ISP MODE ERROR].. I am doubting whether controller is gone bad... How to find where the problem is??
hii yadavvlsi... RTOS also hangs if you dont use properly..In my case it happened... I was using FREE RTOS for UC3B0256 [AVR 32 bit]... Due to stack overflow my code hangs.. RTOS never hang up is wrong one...
Measure the voltage at P1.0 [Input]... As per this program logic if input is HIGH, then making output HIGH else output LOW.... Check your circuit connection properly or else put your schematic here...
