PIC16F887 Bootloader (by IngeJacobo)
Would be someone so kind to help me to find a bootloader for PIC16F887? i been looking for it and besides the tinybootloader im unable to find another to directly be loaded in that PIC. any help will be useful. thank you all.

Try winpic800.
PIC16F887 Bootloader (by IngeJacobo)
Thank you Evan, this program is ok and in fact it has 4 bootloaders, unfortunately no one is applicable to the PIC16F887, anyway your help is been thankful.
Im Building a Hardware PLC platform with this PIC and need the bootloader to make life easier at programming it with LDmicro, anyone have done something like this? as soon as i have the board finished , i will post the EAGLE files here....is that possible Jonathan?? Best Regards you all

Hi,
Does someone have a tiny bootloader .hex file for a 16f887 with 20 mhz xtal Thanks

Hi IngeJacobo !
I made a similar project with 16 input (analog or digital) and 14 output (1 PWM)... basicaly the CPU board is just a 4" x 4" pcb with pinheader for input and output card, so i could mix all kind of input and output card (exemple, 4-20ma input, 120VAC opto input, 12VDC input, 12VDC relay output, 120VAC opto output...) -Programmable with all kind of language -Onboard max232 for rs-232 communication -ICSP for pickit -Bootloader with tiny bootloader (reset CPU with DTR or RTS line) -Onboard Status led -Reset switch -Single sided PCB -20 MHZ xtal I made the IO headers compatible with the old GE FANUC PLC card, because I got a truck load of them... and I neaded a solid platform to do all kind of automation If you are interested I could post the eagle files and picture here Thanks Pornchai, I will guive it a try... By the way I asked the hex file for this project Thanks

Please Max will You do it.

I will post it as soon as everithing is 100% functional... but for now I got some trouble getting the bootloader to work
Pornchai>> did you try the (16F887_20.hex) file... What is the speed ? I`m not able to get tinybld.exe to communicate with the PIC, more investigation is neaded !!!

Pornchai>>
Hi, this is confirmed, 16F887_20.hex is not working... I have tried to change the fuses configuration, but it just won't work It work perfectly with the code that came with tiny booltoader... 4 mhz internal and 8 mhz internal, but I want to use my 20 mhz xtal
MAXPLC (by Max)
Finaly I decided to modify the bootloader code myself, and that was the best thing to do... This is the (MAXPLC) project, feel free to use it or modify it if you need
In Eagle hit RASNET before printing the PCB (Ground plane) (please refer to tiny bootloader web site for software help and term of use) Feature -14 Input Analog or digital (No pull up or pull down resistor) -16 Output (500ma sink) -Programmable with all kind of language -Onboard max232 for rs-232 communication -ICSP for pickit -Bootloader with tiny bootloader (reset CPU with DTR or RTS line) -Onboard Status led -Fused input (range from 7 to 30 VDC) -Reverse polarity protection -Single sided PCB -20 MHZ xtal -Pin headers for input and output (pin compatible with old GE Fanuc PLC IO card)
