Hello, I had the BX24 working great with the LCD+ and a GEMINI telescope mount using com3. When I added a third device on com3 things went to pot. LCD+ inpin=5, outpin=6 GEMINI inpin = 7, outpin = 8 Pic-Servo inpin = 9, outpin = 10, tried on 11, 12 as well. I

I'm working on a project where I'm trying to navigate a 4WD skid-steer bot using data from a gps. I have a BX-24p in a Lynxmotion mini atom bot board. Pin 20 is connected through a level shifter to the rs-232 interface of a handheld gps (Garmin Legend). The gps streams data in standard 4800 81N nmea format over the serial link. I use com3 on pin 20 to read the se

I have configured 2 pins for com3 to communicate with a Siemens C35 using its RX,TX pins so far so good i can communicate with the cellphone, but in order to the cellphone don't loose its network signal the voltage in the RX pin must be limited to 3V to communicate with correctly and without the phone loose its network signal. How can i make the voltage come down from 5v(comp3 RX) to 3V(cellpho...
Define two simultaneous serial ports with DefineCom3

Using a BX-24, I need to define two simultaneous serial ports using DefineCom3. Com1 is already used for another task, so I can not use it. For example, I could use pins 9&10 for my first serial port and pins 11&12 for my second serial port. To switch between ports, I would need to close Com3, use DefineCom3 to change the I/O pins, open Com3. T

Hello, I'm a new user of Bx24 and I have ploblems with the instruction CpuSleep. In my program I am using com1, and com3, and 2 pins are ADC. I would like to call CpuSleep after a time without any change. I have seen an example (Low_power_App_Note_Bx24), but when I use it in my program, it is became hung up. Please, I need help.

Well, I think this will be pretty easy. I think that you are saying you need to send the SSC-II the command 255, followed by the servonumber, followed by the position in ascii. So you need to define com3 at a certain baud rate, with a certain input and output pin. To do this you will need input and output queues. Maybe 10 bytes in each queue unless you

Has anyone ever tried use Bx-24 to control an Appdig Ocelot??? I've tried, but no results. I used the Com3 and a TTL signal converter. The communication parameters are correct (9600,1 stop bit, no parity, no handshake). The communication protocol is correctly implemented !! I tested everything with a serial protocol spy!

Hi all, Hoping to get some help which may be of interest to everyone. I want to use a BX-35 to maintain two RS-232 ports. I have com3 working without difficulty, talking to the LCD+. I want to be able to load my program, disconnect from my PC, and then connect com1 to another piece of hardware that wants to talk to an RS232 interface. I know that piece of hardware works, because I ...

Hi all, Here is an example of some code that reads two buttons to increment two variables i and j and display their values on the LCD via com3. You can really upset this program with quick or slow botton presses and it will reset at different stages. Any ideas
