Bootloaders

USB Boot Loader

hi,

Looking for a boot loader that will work as following:
I will copy a hex file to a USB stick.
Then The USB stick will be attached to the USB host connector of my board.
On power up the boot loader will detect the existence of the hex file on the USB stick and will program it to the MCU.
if no hex file found the boot loader will switch and run the existing application.

comments:
1. MCU: PIC32MX7xx
2. Since the application switches ( application settings) could not be changed in the program, it should match the switches of the boot loader code.Thus, source of such a boot loader will be very appreciated.
3. it is OK to assume that only a single hex file is on the USB stick and that it is located in the root directory. it is also OK to assume that the file name format is 8.3 (DOS naming format) and if needed you can assume that the hex file will be always named App.hex

Thanks,
M. Hooper

MAX11802 Touch Panel SPI Routines

Hi All,

I would like your help for some SPI routines for the above touch panel controller (initialise, read touch coordinates etc). This controller is featured on the displaytech INT043BTFT-TS TFT display which also uses the Solomon SSD1961 display controller.
Also does anybody know if I can use the SSD1963 library routines in MikroC Pro PIC32 compiler and Visual TFT to control this TFT display.

C code for I2C 20X4 LCD with PIC16F1826

If someone could assist me with a code example for using a 20x4 LCD on I2C bus on a small PIC16 I'd appreciate it. I can't find examples of this anywhere.

Thanks,

Internal MCU modules

hardware UART and hardware/software IC2 on PIC16F1618/PIC16F1708

I am trying to get UART and I2C work on PIC16F1618 and PIC16F1708, one at a time.
I could not get it working on pic16f1618, so I tried on pic16f1708. but couldn't get it working on that either.
I have worked on hardware uart with pic18f45k22..
I need sample code for hardware UART, hardware I2C and software I2C.
I am using "MikroC for PIC", which has all the libraries built in, but somehow they aren't working for me., or I am doing something wrong this time. I got software UART working, but not hardware UART, hardware I2C and software I2C.
Also, I don't know how to use "remappable" functions.

I will be very grateful if someone can post a sample code for the above mentioned PICs.

Thanks.
