✅ Chip Enable Program Error - SOLUCIÓN. Usbasp con progISP

Summary of the Video’s Technological Solution

The video explains how to fix a “chip enable program error” encountered when using a USBasp with progISP to program a microcontroller. Even if progISP shows success initially (green status), the error can appear once the chip is inserted and a Read / auto-detect is triggered.

Root Cause (as described)

• The issue is likely due to the programming frequency being too high for the target chip’s configured clock/fuse settings.
• The datasheet indicates there is a jumper setting for frequencies lower than 1.5 MHz.
• Based on the fuses, the chip appears to be running with a divider set to ~1 MHz.

Fix / Tutorial Steps

1. Use a jumper wire to connect the board’s two specific jumper pins that correspond to < 1.5 MHz operation.
2. Insert the chip and click Read.
3. Verify that the tool reports “read successfully” and that programming can proceed normally.
4. The presenter demonstrates that:
   • With the jumper installed (low-frequency mode): reading works.
   • Without the jumper (higher frequency mode): reading fails again with “chip enable program error.”

Additional Guidance

For this particular setup (“this delivery” / board configuration), the presenter recommends leaving the jumper in place, since it allows reliable operation without the error.
