I've seen decoupling capacitors on Nigel's tutorial about the Wireless board. I've seen a lot of applications around the web and they are not using any capacitors. It is also low cost in addition to its high clock speed. This also make it code extremely efficient, allowing the PIC to run with typically less program memory than its larger competitors such as 8081 based microcontrollers. I might still encounter problems not on PIC part since this is a big project so you still might see me posting for new threads in the succeeding days.ĮDIT: Do I need to place capacitors on the RX and TX pins of the PIC? I don't have any idea about this. This unit consists of microcontroller, which uses PIC 16F877A microcontroller due to its reduced instruction set computer design. Now we can show this to our exhibit which is 3 weeks away. ![]() Next time I'll encounter this problem, I'll always go for hardware connections first than going right away to my program code. Sorry for the headache I gave to the two of you. ![]() I figured out that the problem is on 1st side, the RF Transceiver's tx pin is loose. I had a trial and error to figure out which pin is right to achieve a successful transmission. Although I'm quite confused with table 1 the circuit for transmission works now. I'm so thankful to have two guys willing to help on solving my problem.
