When I'm using a low-power (5V , ~10 mah) external trigger source my PIC wont "See" the interrupt. I tested with the logic-analyzer and the rising edge generated by the external trigger is t ...

Problem solved. The problem was FTDI latency time option. Once I set that to 1ms in the FTDI driver ( Default 16) it worked as it should. Hope to help someone today. Thank you Temtronic for your input ...

Hello, I have the folowing question/problem. I'm communicating with 2 18F PICs ( each to another) via UART. The communication is going just fine. But when I put the computer between them (com-to-com s ...

Hi , thank you, the 100R resistor did not work , however with a 2KOhm resistor it works , no more parasitic power , yey Very Happy

thank you again

Hi , I`m having a problem with parasitic power on my 18f PIC. I have a power switch to turn ON/OFF the circuit but it wont work because with a PL2032 USB/UART converter the PIC gets parasitic power an ...

Hi again. After 2 weeks of strugle..no..I did not solve it..:| How Is possible when I print from a buffer created by INT_RDA2 and put the character on Uart1 and then get it back(echo prevent), to get ...

Sorry Asmboy , but I dont understand this part "never known the code " Embarassed

..could you please rephrase...I`m not such a fine english user.

I understand. I`m gonna use the TXSTA TRMT flag to check if the character has been shifted. Hope will work. Thank you very much

Hi , at each UART is this :

Hi , the UART1 TX/RX are connected together via a open collector buffer , UART2 the same, the purpose is acting like a 1 wire databus , preventing the echo getting in the receive buffer.

Hello , I`m trying to clear the UART incoming buffer but It just wont work...I look on the forum and looking on the 18f25k22 datasheet I come up with this code but it still wont work...

How do I send 9 bits char? Using 2 stop bits?

Thank you for all your inputs. The incoming burst is relativ small ( 100 chars) so it could be easy managed by a buffer. The problem is that when I output the characters with a 50 us delay( needed as ...

Hi. Using 18F25k22 ( 2 UART) I'm trying to get data from one UART With a 57600 bps, and send it over the other UART with 9600 bps. The problem is that the data comes too fast from the 57600, and the 9 ...
