TinyBootLoader+ BootLoaders
A bootloader, also known as a boot program or bootstrap loader, is software that loads into the program memory of a microcontroller after start-up. The bootloader permits easy updating of the user program via serial communication, then the bootloader then passes control to the user program.
Developing custom bootloader code can be a complex and a time consuming process. To assist developers the PICKitPlus provides a service that will generate bootloader firmware for your specific microcontroller.
We make it very simple. We have developed automated software that means we can easily configure the bootloader to meet your needs.
What can you change to make it specific for your needs?
The bootloader is a serial bootloader using the USART of the microcontroller.
You can configure the following the parameters.
- Configuration - we provided a guide to make this easy.
- Frequency
- Baud Rate
- Startup Delay
- Serial Ports - either PPS or AFP
To obtain ?
Just drop us an email stating your requirements. Send us the completed form, see below, to pickitplus@anobium.co.uk.
What are the supported microcontrollers?
The table below can be used to identify the correct bootloader for you.
If your specific microcontroller is not listed. Please ask us as we may have omitted. But, to determine the microcontroller requires a USART, internal oscillator and Self-Write capability - most modern Microchip microcontrollers.
| Microcontroller type | Supported microcontrollers | Comments | ||
|---|---|---|---|---|
| Legacy 16F microcontrollers |
PIC16f
|
The bootloader is less than 100 words, uses USART, the internal oscillator | ||
| Advanced 16F microcontrollers |
PIC12f PIC16f |
The bootloader is less than 100 words, supports PPS and HEF or SAF. | ||
