First let me say that I think on the onset for a non programmer and people just starting down the path of micro controllers that flowcode is a wonderful product. I have one major issue. Support Support Support Support. If you don't have the documentation you really should consider offering some kind...

Ok scratch that I was looking in the wrong section of the data sheet. I found bit 5 of register address 8ch RCIE in PIE1 is the correct address and enable bit and that bit 5 of Address 0ch RCIF is the correct flag bit. I tryed to put these values in as is with no additional enable code and here what...

Thanks Ben. I took your advice and done some reading through the forum and the data sheet for the F1690 and on page 133 of the data sheet it say that the enable register address is 18h is that what goes in the custom interrupts Enable register? It also say that the enable bit is Bit 7 am I correct w...

Ok I think there are other issues with the FCD. The error's gone but the interrupt's still not working, are there other issues with the 16F690 file. From the beginning the timer1 and timer0 were working. After I had the problem caused by the RB Port change interrupt the timer1 and timer0 stopped wor...

Thanks I'll give it a try.

I also notice that in the Interrupt list there is an RB0 But the data sheet for the 16F690 does not have an RB0
pin. Please help with this.

Ondra

I really need some help on this guys.

Any opinions on this one?

Ondra

I'm using the PIC 16F690. Its a pre-set interrupt.

Good day all. I have a program where I am using timer 1 to maintain a time clock and flash an Led as a status indicator. I also have in main a loop containing an RS232 component receiving data and updating a variable which is then bit banged out at 2400bps. What I noticed is that the RS232 works fin...

Compiler error. Benj or Steve I think this might tie in to what was done in this situation. When I try to use the RB Port change I get this error. The timer 1 is working fine. Ondra C:\E-Tank\flowcode\ElinK\BBRS232.c(397:9): error: unknown identifier 'RBIE' C:\E-Tank\flowcode\ElinK\BBRS232.c(397:9):...

Thanks Benj. It looks a bit much for me right now. I'll work with what I have until I get pressed.
You've been a big help, thanks for your time and patients on this one.

Thanks Benj. I made the change and it works. Another issue though. I got he bit bang Tx and Rx working separately but they don' t work together. Here what I have. In main I have: loop while 1 Data=RS232(0)::receivRS232Char(200) if Data<255 Call macro BB_Tx end if BB_Rx return val = In if In<255 Call...

Ok. Sorry I'm still on this topic, but here's the situation. Using the RS232_RX.fcf example I set the bit delay to delay_10us(41); that's to receive at 2400bps. I set the delay and a half to delay_10us(62); in the decision "In < 255" of the main macro I put an RS232 send macro call with the paramete...

Thank you so much Oh Great wizard of the Flowcode realm.
I'll let you know how I get along.

Hi Benj thanks again for your help and pleaseee don't get tired of my slowness. I'm an electronic hobbiest. I'm an electrician by trade and new to microcontrollers. I've been at this bit bang receive since last Friday. Every day for at least 2hrs a day reading everything I could find on the forum an...

Hello, is anybody out there.

Thanks Benj it's working. I'm not finishes though. I'm now trying to reverse the data flow. I want to receive on the bit bang port and transmit through the RS232 component. Here's what I have. I tried to follow the instructions you gave for bit bang receive. I changed it up many time as it made sens...

Tanks Benj it's working. I'm not finishes though. I'm now trying to reverse the data flow. I want to receive on the bit bang port and transmit through the RS232 component. Here's what I have. I tried to follow the instructions you gave for bit bang receive. I changed it up many time as it made sense...

Ok here's more detail. In a loop I setup an RS232 component to receive into a variable named dataout. I put the bit bang macro in the loop with the RS232 Receive macro with dataout as it parameter. I connect hyper term to both in and out DB9 conn and what happens is that the key press are passed thr...

Thats what I thought, and I did try it. Maybe I'm not understanding how to use it. In the RS232 Receive macro I put for parameters = 1 and for return variable = Data. Is that right? If it is, it didn't work. I even tried to putting the macro call in a loop. No luck. I tried converting the byte data ...

Thanks Benj. I set the code to transmitting at 2400bps and it works fine. To take it further here's what I want to do. I want to use the RS232 component to receive data that I send from Hyper terminal and then bit bang out the data using the Bit bang RS232 Code thats working. I took your advice and ...

Thanks Benj. Two things. 1)In both example you show outputing a single letter. If I wanted to output a word or phrase would it be as simple as Data = "whatever word, phrase or number" or would there be other manippulations needed. 2) What is masking off a single bit. What does "maskdata = data & 0x0...

Thanks Ben. I spent some time over the weekend reading what I could find on the topic of bit banging. I think I understand what's going on but I would like to learn more. I couldn't get the device working. But that may be a device issue. I will talk with the FTDI tech people today. Back to the bit b...

Thanks Ben. I was thinking that the SPI componet would automatly impement the SS pin. i.e I would just connect the SS pins from both units along with the SCK, SDI, SDO and just start sending data with the SPI component handling all the protocol stuff. This is the instructions for using a device that...
