 Forum: General CCS C Discussion Posted: Fri Feb 04, 2022 2:50 pm Subject: float variable problem |
| Look at the symbol table. (it's in the .SYM file in your project folder)
Notice that 'string' has only 1 byte of memory assigned to it. So when you write to 'string', it's over-writing variables th ... |

| 595s are used to control 16 relays (via ULN2803). Nothing special. Have some 1 I2C sensor, one 4-20 mA sensor and one IR sensor (digital output).
Nothing complex. Root of the problem is that it ... |

| Hi to everyone!
I have a really strange problem. It took me 2 days to find out what is happening, but I still don't know why. MCU: 18F87J11 Compiler version: 5.075 This works. #include ... |

| Hi temtronic,
I only have FT232 and MCP2200 chips on hand. I do not have any problem using them except this XON/XOFF thing in combination with TeraTerm, RealTerm or any other serial port except SI ... |

| That is surprising.
Very! The point about SIOW, is that it turns this on. Remember all the serial programs merrily change the settings while they are running. OK, lets say software (in this ... |

| That would mean there are two problems.
1. MCP2200 driver which doesn't work with XON/XOFF 2. TeraTerm and RealTerm do not work with XON/XOFF I can't believe that Microchip has this kind of pro ... |

| Hmmmm, few new things.
With FTDI chip on its latest drivers I see the difference in comparison with MCP2200. When using MCP2200 DC3 and DC1 are passing through. But, with FT232RL they don't. ... |

| I already have version 2.12.28 from 16.8.2017. Acording to FTDI website it is the latest one for FT232RL.
It does not work with TeraTerm, but with SIOW does. |

| Yes, SIOW handles it on its own.
I just tried to transfer the file to COM port in command prompt. I got the same behavior. So, MCP2200 drivers are the source of the problem. Or it might be OS. ... |

| Already tried CR on receive and transmit in TeraTerm, nothing.
YAT (Yet another terminal) has option to turn this off, doesn't work. I am googling about TeraTerm XON XOFF control and it seams ... |

It is the only thing that can stop the transmission while the programming actually takes place. It handles this internally. Now, ... |
