Also, some of those glue types release fumes when they are drying. The fumes can affect other parts of the circuit.

Use a logical analyzer to see what's coming out of the chip. Compare the output of the SEROUT2 to the output of the HSEROUT2 using the logical analyzer. You might think that your output is 115200,...
You might want to double check that you are setting the hardware communication correctly. I have used the code below to set the HSEROUT/HSERIN for the 18F4550. You might want to check the correct...
I have used hot glue before to secure a Dupont socket onto a header pin. But, even when I don't use the hot glue the connector never moves. Unless there is a lot of vibration, I don't think the glue...
I used Pspice from Orcad back in my school days.
So far it hasn't fail yet with a 9600 baud rate, but I can live with a very low failure rate.
Yes, that explains everything. Unfortunately, I can't use the HSERIN/HSEROUT ports available in the 18F4550 because they are already taken doing the hardware communication. Increasing the baud rate...
The PIC ports with HSEROUT and HSERIN are already taken. Using a baud rate of 9600 instead of 19200 made a difference. It is now working fine. The USB Darrel's interrupt takes micro seconds to...
The sending device has the typical 18F4550 USB setup and it is set to "Define OSC 48". The receiving device is set to "DEFINE OSC 16".
There is probably a little bit of both. I did a search in the forum, but couldn't find anyone having the same issue.
Tumbleweed, I had very strong suspicions that the issues were in the communication lines. I changed the Baud rate from 19200 to 9600 and I haven't got anymore wrong data at the receiver. I remember...
Ioannis, yes I'm doing data validation checks all the time. The first byte of the array is always 174. If this condition is not met, then the reading is discarded.
There is no much code to show here. I know device A is sending the right data because I can see it with a logical analyzer. I know device B, like 1 out of 5 times, is reading some bytes wrong because...
I tried removing the 10k resistor and I'm still having the same problem. The PICs are in two different PCB boards. The serial communication is taking place over a 3ft cable. The cable has 2.5mm mono...
Hi, I have two devices communicating with SERIN2/SEROUT2. Device A, a PIC18F4550, sends data to device B a PIC16F19197. I'm receiving the data at device B using SERIN2, but like 1 out of 5 times I...
I had a PBP project to write to a SD card and it worked. That was many years ago and I don't remember the details of it, but it works. Attached is the sample code that I downloaded from the internet....
Thanks, I will try both of your suggestions.
I sent these 65 bytes every 100 mS. The data rate of the HC-05 seems to be high,
...
No, that space shouldn't be there. There are 64 characters followed by a comma.
I'm using an HC-05 module to send data to a PC or cellphone.
Hmm, how is that going to help? What amount of delay should I use?
The data package looks like this 432551346666666600000000000000000000000000000000CCCCCCCCA98BB79A,. This is just 32 bytes in HEX format followed by a comma. The comma is just to delimit the packages....
Hi, I have an array of 32 bytes. I need to send it to a Bluetooth module in HEX format. The only way I have been able to do it is,
FOR I = 0 TO 31
SEROUT2 PORTC.1,84,[HEX2...
This is not a bug. The programmer should put a RETURN at the end of every SUB routine. There can be some conditional RETURN commands too. You should organize your program such that every SUB routine...
Many car manufacturers canceled their chip orders at the beginning of the pandemic. The chip companies retooled their equipment to make chips for the electrodomestic industry. Many items like tablets...
