Thanks

[@fahimi.saiyed8939]

Can you tell me which software ? And can i Program atmega32 using AVRasp or FT322xx programmer with the Avrdudes application or other?

[@learningmicrocontrollers3561]

mention complete model of microcontroller are you talking about ATmega328p ?

[@JaySubramaniam-u4p]

you have a PIC 3.5 to download the code to the PIC so why use the USB CH340 ?

[@learningmicrocontrollers3561]

@@JaySubramaniam-u4p bcz USB is used for data transfer to PC You cannot use PICKIT to transfer or receive data bcz that use flash method of burning code

[@rajithperera9040]

Can we connect this to an android smart phone instead of a computer and perform this test?

[@learningmicrocontrollers3561]

Yes sure You need an OTG and some serial app There are so many in play store

[@yasirh2004]

Is there any way to burn code on the pic using ttl or using rs to usb cable and max232 ic how they made pickit2 to burn hex using usb then

[@learningmicrocontrollers3561]

For that you need a good pic18 Capable of using HID bootloader in tools from mikroC Crystal must be above 40MHz

[@yasirh2004]

Learning Microcontrollers // i already have one pic18f4550 and i have usb to rs cable and max232 what should i do next

[@learningmicrocontrollers3561]

@@yasirh2004 you need a device like ch340 usb to ttl converter Connect it to pc Install drivers Go to mikroC tools In end you will see usb bootloader Click it Select pic18 Then select code and click on upload If pic you have supports it It will work

[@yasirh2004]

Learning Microcontrollers // i’ll try this method really appreciate your help thank you very much

[@moinshaikh6684]

Can we burn code in PIC16 microcontroller using this CH340 porgrammer which you're using in this video..? Sir please guide...?

[@adhil8918]

Thanks bro

[@ar.mamunhossain9592]

Will it work for PIC16C56A?

[@learningmicrocontrollers3561]

it will not bcz you need a UART port only those PICs which have UART port will work.

[@imranarshad4737]

So. Real... Nice!

[@synth1002]

Tike. Can you make data logger with this. Please make tutorial about connecting PIC to PC and logging temperature data.

[@learningmicrocontrollers3561]

Yes sure Will make a video soon

[@synth1002]

[@shradhas45]

Is it necessary to write UART code to dump using usb 2ttl

[@learningmicrocontrollers3561]

Yes... Because we are using TX and RX pins to send and receive data... Without code PIC wont be able to understand whats comming... there some PIC usb boards for burning they use same device as on board component... they use additional chip which burns this code with everytime we use usb burner to burn... you can do the same but for that you have to permanently burn the uart code in pic yourself. Without uart port initialized PIC cant interface with any UART device. But if you do this then you can use this same device to burn any code in PIC this device is 10 times cheaper then PIC kit 3 or any other board. But require effort.

[@electricalcoder3025]

can we put this pic in a bread board and connect to pc using usb to ttl ...will i be able to upload the code?

[@learningmicrocontrollers3561]

For uploading code using ttl to usb devicr you need a PIC which can support a crystal of 48MHZ or above Mostly PIC18 support this crystal Then you go to mikroC there in tools goto HID bootloader Connect device and ttl to usb device Then press upload code That will do

[@electricalcoder3025]

@@learningmicrocontrollers3561 yeah thanks dude...have ever did it directly without development board or is it successful there less tutorials on internet regarding that

[@learningmicrocontrollers3561]

I will make a video regarding that soon Everything that i show works on breadboard aswell

[@mustaphasabir6685]

Thanks dear

[@hamzouz1229]

Thank you. Can we burn a hex file or read firmware using this module?

[@learningmicrocontrollers3561]

For that you need USB supported pic Having above 40 MHZ crystal
