# PCB reflow firmware
|
|
|
|
|
This firmware is for the PCB reflow hotplate designed by Spatz.
|
|
|
|
|
|
|
|
|
|
It has the following features:
|
|
|
|
|
- reflow profiles
|
|
|
|
|
- OLED display
|
|
|
|
|
- profile PID tracking
|
|
|
|
|
- temperature setpoint tracking
|
|
|
|
|
- safe voltage calculation
|
|
|
|
|
- memory validation
|
|
|
|
|
|
|

|
|
## Build and load process
|
|
|
|
|
to build and load, you need a UDPI programmer and core definitions for the Atmega4809.
|
|
|
|
|
|
|
|
|
|
If you don't have a UDPI programmer you can use another arduino like in this link:
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
You can download the Atmega4809 definitions here:
|
|
|
|
|
https://github.com/MCUdude/MegaCoreX/tree/master
|
|
|
|
|
|
|
|
|
|
Make sure the DallasTemperature and Adafruit display libraries are installed.
|
|
|
|
|
|
|
|
|
|
build and load through the arduino IDE as normal. Select the Atmega4809 as the target
|
|
|
|
|
and make sure the correct programmer is selected.

2022-05-31 22:57:08 +02:00
|
|
|
- Needs a good amount of cleanup and refactoring
|
2022-05-31 22:54:43 +02:00
|
|
|
- Has a hack estimation for minimum PWM, need to find a way to improve this
|
2022-05-31 22:57:08 +02:00
|
|
|
- should switch buttons to bounce2
|
|
|
|
|
- if there's no current sense, write a function to approximate resistance based on temperature
|
|
|
|
|
- validate temperature estimation function is correct across multiple boards
|
