Hai,
When I was unable to drive the pin just like other pins, I thought it is an open-drain output.
So, I tried using a 10k pull up resistor,but it didn't worked.
Then I've made it open drain by setting ODCAbits.ODA4 = 1; and enabled the internal pull up by setting the corresponding CNPUE1...
Hai,
Thanks for the reply.
I have already set it as digital output using TRIS register, and this pin is not multiplexed with analog input. It is multiplexed with these ,PGC3/SOSCO/T1CK/U2CTS/CN0/RA4, but I am not using any of these peripherlals.
Hai,
I am trying to use RA4 pin of PIC24F16KA101 as digital output.It is connected to one of the segments of the 7-segment display. But it is always giving a constant voltage of about 800mv. I am not able to drive this pin.
I checked the datasheet to know if it is an open drain, but that is not...
Hai,
I know this is a very late reply. I'm just posting it to share what I found out.
In sim300, client and server cannot be active simultaneously. One should change the configuration when needed.
So, I used sim900 which support multiple client- server connections and both client and server can...
Hai,
I found out the exact problem. It was my own fault.
The weather station has RS 422 OUTPUT. I'm converting it to TTL output (5V) .
I've taken the RS422+/- signals from the converter IC in reverse.
i.e,RS422+ to the -ve pin and viceversa.
Thanks
Hai,
Are you getting +CMGS response after sending message and are you able to send more than one message?
I think you have to send 0x1a, not "0x1a" to end the message.
Also, if you use AT+CNMI=2,2,0,0,0, Sim 900 will send the message directly to the device instantly on reception.
Hope this helps,
Re: HOW to receive string using uart on pic18
Hai nick703,
What I understood from the post is that you want to receive a string through Uart, but you don't know the length of the incoming string or they are coming randomly. If the string doesn't ends with a particular character such as CR or...
Hai,
Thank you for the reply.
In the datasheet of ADC, it says that it can wake up the Mcu on interrupt if CPU priority is less than ADC interrupt priority.
and
But I am afraid that as I am sampling continuously, ADC will give interrupt every time, even when the input is zero.
Thanks
PIC wake up on ADC trigger (NOT Duplicate post)
Hai Experts,
I am using PIC24F16KA101 for reading ADC. Adc signals will be coming randomly, so I am putting the Mcu in sleep mode.
I like to wake up the mcu, when the signal crosses a threshold value.
When I googled this, I found many topics...
Hai,
Ok, so the code is compiler generated. I was searching for the source code of builtin functions in the compiler installed directory. Now,I saw the assembly code in Disassembly listing.
Thank You
Hai everyone,
I am asking this just out of curiosity.
I am using Microchip C30 compiler to develop EEPROM driver code for PIC24F.
During this I used C30 builtin functions such as
__builtin_tblwtl(), __builtin_tbloffset etc.
How can I find the location of builtin functions? From Wiki I found...
