    Atmel UC3C, Ring Buffer--> write TCR-register during PDCA active

    Dear all, I'm just trying to understand UC3C ring buffer functionality. One question I got is whether it's possible to write TCR register during PDCA channel is active... From datasheet TCR register is generally read/ write-able. But in PDCA text it only states that the register is readable at...

    MMC problem - library functions are not working

    mmc_fat_init problem since I'm not fimilar with the board you mentioned, here just a rough summary of the obstacles I had to overcome before the MMC worked. I'm using the FATfs-module which i adapted from PIC24 to PIC18F6722: 1. MMC only accepts clock frequencies up to 400kHz during init. ->...

    Time accuracy problem with DS 1307.

    Hi, have you considered the layout rules in the datasheet? They clearly pointing out, that digital circuits near the DS1307 can stray into the clock generation. If you have it on a module that just try to put it away form the rest of the circuit.

    Orcad Layout: panelization

    Hi, thanks for your reply.... No, I don't want to gibe my PCB to a board fabricator. More or less I want to reduce my effort when I have small size circuits which I need rather often. Therefore also my need to keep the drill holes open. It's simply easier to drill them by hand... The tools...

    What does 64*8 mean in DS 1307 datasheet?

    Re: Regarding RTC Hi Viswanath, I'm not fimilar with this controller but I had to programm a 8051 in the past. Internal or external just make a difference in accuracy of the clock frequency. Since I2C is a synchronous bus a tolerance in the clock speed of SCL(if it not exceeds the upper...

    What does 64*8 mean in DS 1307 datasheet?

    silabs rtc internal oscillator Hi, 64 bytes with 8 bits. 8 of these bytes (adress 00h to 07h) containing the time information. The rest of them are non volatile SRAM. Closer information you'll find in the datasheet. regards reiniheini

    Orcad Layout: panelization

    Hi guys! can anyone of you tell me how to panelize and board out of Orcad?? Since I need to have the drill holes open, the standard gerber tools which I've found (gerbtool and gc-preview) are not an option. Thanks in advance! regards Reini

    buck converter using LM3477A

    Hi there, i built an dc-dc converter using a LM3477A. In generous I used the components similar to that which are mentoned in the datasheet application. The main difference in my design is that the output voltage should be adjustable. But murphys law means: Everything else is swinging but not...

    glas coating for diodes or resistors

    Hi there, i need to know how diodes or resistors (including NTC´s and PTC´s) are surrounded with glas! I´m even not sure if this is real glas or if its some kind of epoxy. Please be so kind and give me some hints about the production process. Thanks in advance. best regards reiniheini

    using the QEI of a PIC18F2331 with CCS

    qei ccs HI everyone, does anyone of you have experience in programming the quadratur encoder interface with the CCS Compiler? I´m using the version 3.148 of the compiler. CCS say´s on there Homepage, that the actual version supports the device? Are there functions to setup the QEI ? Thanks...
