tip
- SHT36 V2 provides Katapult firmware with USB and CAN connections, you can burn it yourself if needed
- Katapult Firmware Burning
- SHT36 V2 is pre-flashed with Katapult firmware for CAN connection at a rate of 1M
Notes
- SHT36 V2 uses three types of main controllers, please do not burn the wrong one or it will not start
- APM 072 and STM 072 Please see 072CAN Firmware Burning
- STM 103 Please see 103CAN Firmware Burning
Firmware Burning Instructions
- Firmware compilation and firmware burning both require the use of a host computer
- SHT36 V2 can connect to the host computer via CAN
- CAN needs to use
XT30(2+2)-F
for connection - Below is the data cable style of
XT30(2+2)-F
Notice
- Mainboard firmware burning needs to be done through Katapult burning Klipper
- If you are sure that the mainboard has already been burned with Katapult, there is no need to burn the Katapult firmware at the end
CAN Firmware Compilation
- SHT36 V2 can only connect to the host computer via CAN
- STM 103 Please see 103CAN Firmware Burning
- APM 072 and STM 072 Please see 072CAN Firmware Burning
Katapult Firmware Description
tip
Katapult was originally named CanBoot, and later renamed to katapult.
- Katapult firmware is a type of bootloader that can be used in conjunction with Klipper. After burning the firmware using methods like DFU, you can use commands to update the firmware with one click.
- Advantage: Quickly double-clicking the reset button or quickly cutting power twice will enter the Katapult firmware, at which point there will be an LED flashing on the mainboard.
- Katapult firmware can only be used to burn firmware and cannot connect to Klipper!!!
- Katapult firmware supports three connection methods for connecting to the host computer, and the firmwares for these three methods are independent of each other.
- CAN connection
- Advantage: After compiling the KLIPPER firmware, you can directly update the firmware using a command, and it has strong interference resistance.
- Disadvantage: You need to know the firmware compilation rate in advance.
- RS232 connection
- Advantage: After compiling the KLIPPER firmware, you can update the firmware using a command, and it has very strong interference resistance.
- Disadvantage: You cannot use a command to update the firmware with one click; you need to manually enter the Katapult firmware.
- USB connection
- Advantage: After compiling the KLIPPER firmware, you can directly update the firmware using a command.
- Disadvantage: A long data cable is prone to interference, which may lead to disconnection.
- CAN connection
