Resolved, AbhijitR and Benj thanks for helping me. Thankful and no more.

hello to everyone I would like to use the internal Eeprom of the chip with flowcode 6, I write very well at address 0 with the value 10, but when I restart the Chip I always read it starting at 0. Can someone please help me ?? I remember having already done a project with Flowcode 5 using the intern...

What I presume is the keyboard Emulator he is still in operation even when the PC is off and when you restart Windows keyboard emulator program is stopped at another point of the main routine. Recoloquei already boot icon in the main routine and also did not work.Any tip and thank you very much .

Hello to everyone. Once more i ask for help to welcome the team of the Matrix.I am emulating a keyboard USB HID WITH THE PIC 18f14k50 and 18f2550. But when i turn off the PC(Computer) the keyboard Emulator is still powered by the USB port of the PC and is in operation. Therefore, restarting the PC o...

I even desabilitei driver signing of Windows 10 and not solved .
will be that someone can pass any site or article for which I can understand why does not work.
Thank you

Hi everyone !!! Always when my Hardware Connector to USB IN WINDOWS 10 is giving is message &Quot;request failed device descriptor " as in the image below. Therefore, on Windows XP and Windows 7 is the operation OK . Will that hid the FLOWCODE USB does not work with Windows 10 .Someone can ...

Hello to all i am having a problem if anyone can help me I am grateful .i did a program with pic 18f14k50 using the USB HID and works very well in WINDOWS XP AND WINDOWS 7.If I use Windows 10 the same program does not work.Anyone can take this question.Please

Hello Benj thank you for answer me.In that case I create a macro to make a positive sweep.

Hello all welcome .I would like to know if i edit the component Keypad to change the logic of the PullDown for Pullup.If it is not possible to make directly in the component .Thanks to all

s it possible to emulate a USB HID Keyboard to work also in the bios of the Motherboard ? Anyone can take this doubt thank you .

Hello everyone I emulei HID Keyboard with pic 18f14k50,but the same does not function in the BIOS.Put another USB keyboard manufactured and works normal . Can someone help me with some explanation .Thanks to all

Hello Benj for me meet my project did an improvisation since my project does not need to be as accurate as well.Then created a flag state when the breakpoint is enabled retrieves this value and when it returns to the MAIN routine he compares if the state flag is true ,just so he enters in the USBHID...

Hello Benj i did test on the hardware with this simple program with the PIC 18F14K50 and 18F13K50 and noticed only with these gives this bug .Noto which returns the interruption normally for the main diagram (main),but he continues to write in the USBHID. Just to add also did testing with the PIC 18...

Thank Benj once more.I could here the project concludes that needed.

Hello everyone, I have reported a bug with the pic 18f14k50 and 18f13k50. When you use an external interrupt (INT0, INT1 and INT2) and inside the interrupt you send a letter through the USB HID, repeating that same letter without stopping. In the flowcode the simulation works fine, however I did tes...

Hello Benj i did test with crystal of 48MhZ model HS trying to use modulo USB and not worked ,but seeing the datasheet vi that can work with crystal of 48mhz but has to be the model EC of 4 pins.There in the datasheet is so CRYSTAL 6Mhz EC/HS CRYSTAL 12Mhz EC/HS CRYSTAL 48Mhz EC Passing on this info...

Returning to the topic to pass on information that I took on another site.To work with crystal of 48Mhz crystal JV has to be complete. As shown in table 2.4 of http:// http://ww1.microchip.com/downloads/en/D ... 41350C.pdf datasheet . CRYSTAL EC

Seeing the datasheet of the pic 18f14k50 can be used in Crystal of 6mhz,12mhz or 48mhz to USB mode.Is it actually permitted use CRYSTAL 48Mhz with NODIV?

Hi I am sorry to resurrect this topic.But now I need to use it with external 48mhz crystal without needing to use the PLL (x 4) has already made several attempts .But i am not able to make USB works with crystal of 48mhz .Windows does not recognize .

Is it possible i implement this serial communication I2C IN SOFTWARE mode between two pic 16f628A?i already used this icone I2C Master FLOWCODE to read and send an EEPROM and works well ,but i don't know if it will work between the pic 16f628A. Then why this doubt

Hello LeighM thanks again.actually have a few pins to saida /entry,why must be serial communication so i use a little door.But thanks for the tip.

Hello thank LeighM the tip above very good .But a doubt,in the programs above uses pic 16f1937 that already comes with I2C and dedicated embedded already.is that with PIC 16F628A which does not have dedicated I2C programs that works ??Can I make this announcement by SOFTWARE?

Hello everyone I have a transmission with the serial communication I2C MASTER ,but i doubt how to receive this data and treats it in I2C SLAVE.Someone can explain me how it works the I2C SLAVE or has some example how to use it ?

Hello i come once more humbly ask for help to Foristas .i'm thinking about implementing a project that consists in communicating two pic 16f628A by serial communication.Because i thought in use via RS232 it would be very easy ,but one of the pic is already using RS232 for another communication with ...

After the tip of the master Benj, I was able to solve and understand what was happening for the non-operation of the Pic 18f14k50 with USB. I actually made my Hardware putting external crystal of 24mhz and with this will not work.Simply this pic 18f14k50 in case you want to use USB will only work wi...
