| Hi,
I've this problem: In the past I read the DataEE during debug (ICD-U40 and PIC18LF4525). Now I've installed a new PC because my old pc is broken and during debug session I see the EEPROM at ... |

| The question is, why the zero between brackets?
I'm using 3 PIC 18LF4525 and the I2C bus. I've no problem for the I2C write operations on the 2 "slaves" chips, but I've an issue in the ... |

| Hi, it wasn't clear what Ttelmah said to me.
I didn't modify the Cypress firmware because I was sure the firmware was right (I use these routines with a lot of I2C ICs in my design); So I supposed ... |

| Hi,
I'm working on I2C protocol to connect a Cypress 68013A (MASTER) and a 18LF4525 (SLAVE). I did a lot of test and now I can read the I2C write operation only with a polling in the main: w ... |

Forum: General CCS C Discussion Posted: Thu Jan 26, 2012 8:39 am Subject: Float performance |
| Good,
I've improved a lot the polling rate, but in some cases the RS232 is blocked by an over-rate. Is there a way to reset/flush the buffer or port? |

I've a firmware on which I need to normalize some result. The firmware has a polling structure and the float division use a lot of time. I don't need a particular precision. When the firmwa ... |

| Thx!
I found the software serial port, but your notes about slow and blocked connection lead me to a different solution. I will introduce a DPDT to swap the connection outside the uC with a use of o ... |

I'm using a 16LF88; in the datasheet the BROWNOUT voltage reset for LF or F version is 3.65V. But if I use a 16LF88 at 3.3V, why is the reset voltage greater than the Voltage supply?????? Am ... |
